Elastomère tèmoplastik (TPE), pafwa refere yo kòm Thermoplastic Rubbers (TPR), se yon klas copolymers oswa melanj fizik polymères—tipikman yon plastik ak yon kawotchou—ki konbine pwopriyete tèrmoplastik ak elastomè.. Konbinezon inik sa a pèmèt TPE yo trete tankou tèrmoplastik (atravè ekstrizyon, bòdi piki, kònen bòdi, elatriye.) pandan y ap kenbe Elastisite a ak fleksibilite nan kawotchou. Kontrèman ak kawotchou vulkanize tradisyonèl yo, TPE yo ka fonn epi trete plizyè fwa san pèt enpòtan nan pèfòmans, fè yo plis zanmitay anviwònman an ak pri-la efikas. Kòm demann lan pou lejè, fleksib, ak materyèl resikle ap grandi atravè endistri tankou otomobil, elektrik, konstriksyon, ak byen pou konsomatè, TPE yo te vin de pli zan pli popilè, kondwi devlopman nan masterbatch espesyalize ak teknoloji extrusion pwepare a kondisyon pwosesis inik yo.
Masterbatch, kòm yon materyèl kle pou koloran ak modifikasyon fonksyonèl nan TPEs, jwe yon wòl enpòtan nan amelyore pèfòmans ak elaji sijè ki abòde aplikasyon an nan pwodwi TPE. Pwosesis la nan TPE masterbatch mande pou kontwòl egzak nan melanje, dispèse, ak paramèt tanperati, kòm TPE yo gen viskozite espesifik, rezistans chalè, ak karakteristik elastisite ki diferan de plastik tradisyonèl yo.

Akòz kontni segondè polyolefin yo, Pwosesis TPO masterbatch mande pou extruders ak bon kapasite melanje asire dispèsyon inifòm nan pigman ak aditif..
1.1.3 Vulkanizat tèmoplastik (VAT, TPE v).
TPV se yon melanj dinamik vulkanize nan polyolefin (anjeneral PP) ak elastomè (anjeneral EPDM). Pandan pwosesis la, se faz elastomèr la vulkanize nan ti patikil ak inifòm gaye nan matris la polyolefin, sa ki lakòz elastisite ekselan, konpresyon mete rezistans, ak rezistans chalè. TPV yo gen pi bon pwopriyete mekanik ak estabilite dimansyon pase TPE tradisyonèl yo, epi li ka kenbe tèt ak alontèm ekspoze wo-tanperati (jiska 150 ℃).
Pwosesis TPV mande pou kontwòl tanperati egzak ak fòs taye fò pou asire vulkanizasyon inifòm ak dispèsyon. Tanperati pwosesis la varye ant 170 ℃ ak 240 ℃, ak materyèl la gen gwo viskozite pandan pwosesis la, ki mete kondisyon segondè sou koupl la ak rezistans mete nan extruders jimo-vis.

TPA se lajman ki itilize nan eleman otomobil (tankou angrenaj, bi), konektè elektrik, ak kawotchou endistriyèl.
1.2 Pwopriyete kle nan TPE ki afekte pwosesis Masterbatch
TPE yo gen pwopriyete inik ki fè distenksyon ant yo ak plastik tradisyonèl yo, ak pwopriyete sa yo dirèkteman afekte fòmilasyon an nan masterbatch ak seleksyon an nan ekipman extrusion. Pwopriyete kle yo konsidere nan pwosesis masterbatch yo jan sa a:
1.2.1 Elastisite ak fleksibilite.
TPEs have high elasticity and flexibility, which means that the masterbatch must be compatible with the TPE matrix to avoid reducing the material’s elastic performance. The carrier of the masterbatch should have good compatibility with the TPE, and the dispersant should ensure uniform dispersion of pigments without forming agglomerates that could cause stress concentration and reduce flexibility.
1.2.2 Heat Resistance.
Different TPE categories have different heat resistance (processing temperature ranges from 150℃ to 290℃). Masterbatch pigments and additives must have heat resistance matching the TPE processing temperature to avoid decomposition, discoloration, or performance degradation during extrusion. Pou egzanp, TPC ak TPA mande pou pigman ki reziste wo-tanperati ak estabilize chalè.
1.2.3 Viskozite ak Processability.
TPE yo gen diferan viskozite pandan pwosesis la (TPV ak TPC gen pi wo viskozite, pandan ke TPS gen pi ba viskozite). Sa a afekte fòs la taye ak transmèt kondisyon nan extruder la jimo-vis. TPE ki gen gwo viskozite mande pou extruders ak gwo koupl ak gwo kapasite melanje, pandan y ap TPE ki ba-viskozite mande pou kontwòl egzak sou vitès ekstrizyon pou evite materyèl debòde.
1.2.4 Absòpsyon imidite.
Gen kèk TPEs (tankou TPU, TPA) gen gwo absòpsyon dlo, ki ka lakòz bul, idroliz, ak lòt defo nan masterbatch la. Matyè premyè yo (TPE, pigman, aditif) yo dwe byen seche anvan pwosesis la, ak extruder la ta dwe ekipe ak yon aparèy echapman vakyòm yo retire imidite ak sibstans ki sou temèt.
1.2.5 Konpatibilite ak aditif.
TPEs often require functional additives (such as antioxidants, estabilize UV, grès machin) to improve their performance. Masterbatch la ta dwe fòmile pou asire ke aditif yo konpatib ak tou de pigman yo ak matris TPE la, evite reyaksyon chimik ki ka afekte kalite pwodwi.
2. Masterbatch pou TPEs: Konpozisyon, Kondisyon pou fòmilasyon ak pwosesis
Masterbatch pou TPEs se yon melanj konsantre pigman/koloran, transpòtè, ak aditif, fèt pou koulè TPE yo ak bay fonksyon adisyonèl (tankou reta flanm dife, antistatik, anti-bakteri) pandan w ap kenbe pwopriyete elastik ak pwosesis nannan materyèl la. Fòmilasyon ak pwosesis TPE masterbatch yo pi egzijan pase sa yo pou plastik tradisyonèl yo, akòz pwopriyete inik TPE yo. Seksyon sa a detaye konpozisyon an, prensip fòmilasyon, ak kondisyon pwosesis nan masterbatch TPE.
2.1 Konpozisyon debaz TPE Masterbatch
Tankou masterbatch tradisyonèl yo, TPE masterbatch konsiste de twa konpozan debaz: pigman/koloran, transpòtè, ak aditif. Seleksyon ak pwopòsyon chak eleman yo adapte ak kalite TPE ak kondisyon aplikasyon li yo.
2.1.1 Pigman/Colorants.
Pigman/koloran yo se eleman debaz yo ki bay koulè TPE yo, kontablite pou 10%-70% nan konpozisyon masterbatch la (depann sou entansite a koulè ak kalite TPE). Kondisyon kle yo pou pigman / koloran nan masterbatch TPE yo se:
- – Heat Resistance: Dwe kenbe tèt ak tanperati pwosesis TPE sib la (150℃-290℃) san dekonpozisyon oswa dekolorasyon. Pou TPE-wo tanperati (TPC, TPA), pigman òganik ki reziste wo-tanperati oswa pigman inòganik yo pi pito.
- – Konpatibilite: Dwe konpatib ak matris TPE pou evite migrasyon, fleri, oswa Elastisite redwi. Pigman ki gen menm polarite ak TPE yo pi konpatib (pa egzanp, pigman polè pou TPU, pigman ki pa polè pou TPS).
- – Dispersibilite: Dwe fasil dispèse nan matris la TPE asire koloran inifòm epi evite tach koulè, tach, oswa redwi pwopriyete mekanik. Fine-patikil pigman (20-40 may) ak aglomerasyon ki ba yo pi pito.
- – Zanmitay anviwònman an: Dwe satisfè estanda pwoteksyon anviwònman mondyal yo (tankou REACH, RoHS) pou evite sibstans toksik oswa danjere (tankou metal lou) ki ka afekte sante moun ak anviwònman an.
Pigman komen yo itilize nan masterbatch TPE yo enkli: pigman inòganik (diyoksid Titàn pou blan, nwa kabòn pou nwa, oksid fè pou wouj / jòn), ak segondè-tanperati rezistan pigman òganik (ftalosyanin ble/vèt, quinacridone wouj).
2.1.2 Transporteurs.
Pòtè yo se matris la nan masterbatch la, kontablite pou 20%-80% nan konpozisyon an, epi jwe yon wòl kle nan dispèse pigman ak konfòme yo ak matris la TPE. Konpayi asirans lan dwe gen ekselan konpatibilite ak tou de pigman yo ak TPE sib la, kòm pòv konpatibilite ka mennen nan migrasyon pigman, koloran inegal, ak redwi pèfòmans TPE. Seleksyon an nan konpayi asirans lan baze sou ki kalite TPE:
- – Pou TPS (SBS, SEBS): Sèvi ak TPS oswa PP kòm konpayi asirans lan, ki gen bon konpatibilite ak pwosesis likidite.
- – Pou TPO/TPE-o: Sèvi ak PP oswa PE kòm konpayi asirans lan, matche konpozan polyolefin nan TPO a.
- – Pou TPV/TPE-v: Sèvi ak PP kòm konpayi asirans lan, ki konpatib ak PP matris TPV la.
- – Pou TPU: Sèvi ak TPU kòm konpayi asirans lan, asire konpatibilite ak matris TPU a epi evite idroliz.
- – Pou TPC/TPE-E ak TPA/TPE-A: Sèvi ak TPC oswa TPA kòm konpayi asirans lan, respektivman, matche ak kondisyon yo pwosesis wo-tanperati ak konpatibilite.
Konpayi asirans lan ta dwe tou gen bon likidite pwosesis, ak yon pwen k ap fonn ak tanperati pwosesis ki konsistan avèk oswa yon ti kras pi ba pase TPE sib la, asire melanje inifòm epi evite degradasyon TPE.
2.1.3 Aditif.
Aditif yo se eleman oksilyè ajoute pou amelyore pèfòmans pwosesis la, dispèsibilite, ak pèfòmans fonksyonèl nan masterbatch TPE, kontablite pou 1%-10% nan konpozisyon an. Kalite ak dòz aditif yo detèmine pa kalite TPE ak kondisyon aplikasyon an:
- – Dispersan: Aditif ki pi enpòtan pou TPE masterbatch, itilize diminye tansyon sifas pigman, anpeche aglomerasyon, epi asire dispèsyon inifòm nan matris TPE a. Dispèsan komen yo enkli sir polyethylene, sir polypropylène, asid stearik, ak anidrid maleik grefon sir. Pou TPE ki gen gwo viskozite (VAT, TPC), yo pi pito dispèrsan segondè-efikasite ak konpatibilite fò.
- – Konpatibilite: Itilize pou amelyore konpatibilite ant pigman ak TPEs, ak ant masterbatch ak matris TPE. Pou egzanp, se anhydride maleik grefon PP yo itilize kòm yon konpatibilite pou TPO masterbatch, epi yo itilize sir an poliyiretàn pou masterbatch TPU.
- – Estabilizatè chalè: Itilize pou anpeche dekonpozisyon pigman ak degradasyon TPE pandan pwosesis wo-tanperati. Estabilize chalè komen yo enkli estabilize fèblan òganik (pou TPU), anpeche antioksidan fenol (pou TPS, TPO), ak antioksidan fosfit (pou TPC, TPA).
- – UV Stabilizer ak antioksidan: Itilize amelyore rezistans move tan ak rezistans aje nan pwodwi TPE ki gen koulè pal, anpeche koulè manyak ak degradasyon pèfòmans anba limyè solèy la ak oksijèn. Pou aplikasyon deyò (tankou pati eksteryè otomobil), UV absòbe ak estabilize limyè amine anpeche (HALS) yo ajoute.
- – Lubrifyan: Yo itilize pou diminye friksyon ant materyèl ak ekipman extrusion (vis, barik, mouri tèt), amelyore likidite pwosesis, epi evite materyèl kole ak ekipman. Lubrifyan komen yo enkli asid stearik, stearat kalsyòm, ak lwil oliv silikone. Pou TPU ak TPA, grès machin ak migrasyon ki ba yo pi pito pou evite afekte pèfòmans pwodwi.
- – Aditif fonksyonèl: Te ajoute pou bay fonksyon espesyal TPE yo, tankou rezistan flanm dife (pou fil ak câbles), ajan antistatik (pou konpozan elektrik), ak ajan anti-bakteri (pou aparèy medikal ak machandiz konsomatè).
2.2 Prensip fòmilasyon TPE Masterbatch
Fòmilasyon TPE masterbatch dwe balanse efè koloran, pèfòmans pwosesis, ak pwopriyete nannan TPE. Prensip kle yo jan sa a:
2.2.1 Konpatibilite Premye.
Konpayi asirans lan, pigman, ak aditif yo dwe konpatib ak TPE sib la pou evite diminye elastisite materyèl la, fleksibilite, ak pwopriyete mekanik. Pou egzanp, lè l sèvi avèk yon konpayi asirans ki pa polè pou TPU polè ap mennen nan konpatibilite pòv ak migrasyon pigman.
2.2.2 Koresponn ak rezistans chalè.
Pigman yo ak aditif yo dwe gen rezistans chalè matche tanperati pwosesis TPE. Pou egzanp, TPC masterbatch itilize pigman ki reziste wo-tanperati (rezistans chalè ≥280℃) pou evite dekonpozisyon pandan pwosesis la.
2.2.3 Optimize dispersibilite.
Kontni pigman an ak dòz dispersant yo ajiste pou asire dispèsyon inifòm. Masterbatch ki gen gwo konsantrasyon (kontni pigman 50%-70%) mande plis dispersant ak pi bon kapasite melanje, pandan y ap ba-konsantrasyon masterbatch (10%-30%) konsantre sou konpatibilite.
2.2.4 Minimize Enpak sou Pwopriyete TPE yo.
Masterbatch la pa ta dwe siyifikativman afekte elastisite TPE a, seri konpresyon, oswa rezistans abrasion. Pou egzanp, dispèsan twòp oswa grès machin ka diminye fòs mekanik TPE a.
2.2.5 Konfòmite Pwoteksyon Anviwònman.
Fòmilasyon an dwe satisfè estanda pwoteksyon anviwònman mondyal yo, evite sibstans toksik oswa danjere (tankou metal lou, ftalat) ki ta ka limite aksè nan mache.
2.3 Pwosesis Kondisyon pou TPE Masterbatch
Pwosesis TPE masterbatch se sitou te pote soti lè l sèvi avèk teknoloji extrusion twin-screw, ki mande kontwòl strik nan pretretman matyè premyè, premelaj, paramèt ekstrizyon, ak post-pwosesis asire bon jan kalite pwodwi. Kondisyon kle pwosesis yo jan sa a:
2.3.1 Pretretman materyèl kri.
TPEs (espesyalman TPU, TPA) gen gwo absòpsyon dlo, se konsa tout matyè premyè (TPE konpayi asirans, pigman, aditif) yo dwe byen seche anvan pwosesis la. Tanperati a siye ak tan yo detèmine pa kalite materyèl la: TPU/TPA se cheche nan 100-120 ℃ pou 6-8 èdtan, TPS/TPO seche nan 80-100 ℃ pou 3-5 èdtan, ak pigman yo seche nan 60-80 ℃ pou 2-4 èdtan. Kontni imidite nan matyè premyè sèk yo ta dwe kontwole anba a 0.1% (0.05% pou TPU/TPA).
Anplis de sa, pigman ak gwosè patikil gwo oswa agglomere yo ta dwe kraze ak tamize (20-40 may) pou amelyore dispersibilité, ak enpurte (patikil metal yo, pousyè) yo ta dwe retire pou evite mete sou ekipman extrusion ak domaj nan masterbatch.
2.3.2 Premixing.
Matyè premyè sèk yo (pigman, konpayi asirans, aditif) yo melanje nan yon mixer gwo vitès dapre rapò fòmil la pou fòme yon melanj inifòm preliminè. Paramèt premixing yo ajiste ki baze sou kalite TPE: vitès melanje 800-1200 rpm, tan melanje 5-10 minit, tanperati melanje 40-60 ℃. Pou mètr ki gen gwo konsantrasyon oswa transpòtè TPE ki gen gwo viskozite, se tan an premix pwolonje, ak dispersant yo ajoute premye nan rad pigman yo, amelyore dispèsibilite.
2.3.3 Kontwòl paramèt extrusion.
Twin-screw extrusion se etap debaz nan pwosesis TPE masterbatch, ak paramèt kle yo (tanperati, vitès vis, presyon ekstrizyon, vitès manje) dwe kontwole jisteman pou matche ak kalite TPE:
- – Kontwòl Tanperati: Se barik la divize an 4-6 seksyon kontwòl tanperati (feeding section, melting section, mixing section, homogenizing section, die head section). The temperature of each section is adjusted according to the TPE processing temperature. Pou egzanp, TPS masterbatch: feeding section 100-120℃, melting section 160-180℃, mixing section 170-190℃, homogenizing section 160-180℃, die head section 150-170℃; TPC masterbatch: feeding section 150-170℃, melting section 230-250℃, mixing section 240-260℃, homogenizing section 230-250℃, die head section 220-240℃. The temperature control precision should reach ±1℃ to avoid TPE degradation and pigment decomposition.
- – Vitès vis: The screw speed ranges from 200-800 rpm, adjusted based on TPE viscosity. High-viscosity TPEs (VAT, TPC) require higher screw speed (500-800 rpm) to generate sufficient shear force for pigment dispersion; low-viscosity TPEs (TPS) use moderate speed (300-500 rpm) to avoid material overflow.
- – Presyon extrusion: The pressure ranges from 5-12MPa, kept stable (fluctuation ≤±0.5MPa) to ensure uniform mixing and shaping. High-viscosity TPEs require higher pressure, while low-viscosity TPEs use moderate pressure.
- – Feeding Speed: Adjusted to match the screw speed and extrusion speed, ensuring stable and uniform feeding. Pou TPE ki gen gwo viskozite, a forced feeding device is used to avoid material accumulation.
2.3.4 Post-Processing.
After extrusion, the strip-shaped masterbatch is cooled (water tank cooling, 20-30℃), granulated (gwosè patikil 2-5mm), tès depistaj (pou retire patikil ki pa kalifye), ak pake (anbalaj sele ak imidite-prèv). Pou imidite-sansib TPE masterbatch (TPU, TPA), se pwodwi a fini cheche ankò anvan anbalaj yo anpeche absòpsyon imidite.
3. Jaden aplikasyon TPE Masterbatch ak Matching Zhuoyue Extruder Solutions

4. Zhuoyue’s Full Series Extruders: Professional Solutions for TPE Masterbatch Processing
Zhuoyue has long been engaged in the research, development, and production of high-performance twin-screw extruders, and has accumulated rich experience in TPE masterbatch processing. Based on the unique processing characteristics of TPEs (high viscosity, temperature sensitivity, moisture absorption) and the diverse needs of manufacturers (different TPE categories, production scales, application fields), Zhuoyue has launched a full series of extruders suitable for TPE masterbatch processing, including HTS BASIC, HTS PLUS, HTS SUPER, ZTE, and HTE series. Each series has targeted performance advantages, providing personalized and efficient processing solutions for TPE masterbatch manufacturers of different scales.
4.1 Core Advantages of Zhuoyue’s Extruders for TPE Masterbatch Processing
Zhuoyue’s extruders are specially optimized for TPE masterbatch processing, with the following core advantages to meet the strict requirements of TPE processing:
4.1.1 Excellent Mixing and Dispersing Effect.
TPE masterbatch requires uniform dispersion of pigments and additives to avoid affecting the material’s elasticity and mechanical properties. All Zhuoyue’s twin-screw extruders adopt an intermeshing co-rotating structure, with a reasonable screw pitch, lead, and compression ratio design. The intermeshing and rotating of the twin screws generate strong shear force and kneading force, which can fully break pigment agglomerates and ensure uniform dispersion of pigments, transpòtè, and additives in the TPE matrix. The mixing uniformity reaches more than 95%, which is far higher than that of ordinary extruders.
Anplis de sa, the screws adopt a modular design, which can freely combine different screw elements (transmèt, melanje, taye lenn) according to the TPE type. Pou egzanp, high-viscosity TPV/TPC masterbatch requires more mixing and shearing elements to enhance dispersion; low-viscosity TPS masterbatch uses more conveying elements to improve production efficiency.
4.1.2 Precise Temperature Control, Avoiding TPE Degradation.
TPEs are sensitive to temperature, and excessive temperature or temperature fluctuation can lead to material degradation (such as TPU hydrolysis, TPC chain scission). All Zhuoyue’s extruders adopt an advanced intelligent temperature control system, avèk 4-6 independent temperature control sections, temperature control precision of ±1℃, and real-time temperature monitoring and alarm functions. The barrel adopts a double-layer jacket design, realizing rapid heating and cooling, and improving temperature response speed. The die head is equipped with an independent temperature control device, ensuring stable shaping of the masterbatch strip.
4.1.3 High Wear Resistance and Corrosion Resistance.
Some TPE masterbatches (such as TPA, TPC) contain high-hardness pigments or additives, which can wear the screw and barrel. Zhuoyue’s extruders use high-quality wear-resistant materials and advanced manufacturing technologies: HTS PLUS/SUPER/HTE series screws and barrels are made of imported wear-resistant alloy steel, undergoing bimetallic composite or laser cladding treatment, surface hardness ≥65 HRC (HTS SUPER series ≥70 HRC), service life 2-3 times that of ordinary extruders; HTS BASIC/ZTE series screws and barrels are nitrided, surface hardness ≥60 HRC, meeting the needs of ordinary TPE masterbatch processing.
4.1.4 Vacuum Exhaust and Moisture Removal Capabilities.
TPEs such as TPU and TPA have high water absorption, and moisture can cause bubbles and defects in the masterbatch. All Zhuoyue’s mid-to-high-end extruders (HTS PLUS/SUPER/HTE) are equipped with a vacuum exhaust device, which can effectively remove moisture, sibstans ki temèt, ak lè nan materyèl la, asire dansite ak bon jan kalite masterbatch la. Degre nan vakyòm se reglabl (0.06-0.09MPa), adapte a diferan kondisyon kontni imidite.
