1.2 Key Properties of TPEs Affecting Masterbatch Processing
TPEs have unique properties that distinguish them from traditional plastics, and these properties directly affect the formulation of masterbatch and the selection of extrusion equipment. The key properties to consider in masterbatch processing are as follows:
1.2.1 Elasticity and Flexibility.
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. Bu chòir gum biodh co-chòrdalachd math aig neach-giùlan an masterbatch leis an TPE, agus bu chòir don neach-sgaoilidh dèanamh cinnteach à sgapadh èideadh de pigmentan gun a bhith a’ cruthachadh agglomerates a dh’ fhaodadh cuideam cuideam adhbhrachadh agus sùbailteachd a lughdachadh.

2. Masterbatch for TPEs: Composition, Formulation and Processing Requirements
Masterbatch for TPEs is a concentrated mixture of pigments/dyes, luchd-giùlain, agus stuthan cur-ris, designed to color TPEs and impart additional functions (such as flame retardancy, antistatic, antibacterial) while maintaining the material’s inherent elastic and processing properties. The formulation and processing of TPE masterbatch are more demanding than those for traditional plastics, due to the unique properties of TPEs. This section details the composition, formulation principles, and processing requirements of TPE masterbatch.
2.1 Core Composition of TPE Masterbatch
Like traditional masterbatch, TPE masterbatch consists of three basic components: pigments/dyes, luchd-giùlain, agus stuthan cur-ris. Tha taghadh agus co-roinn gach pàirt air an dèanamh freagarrach don t-seòrsa TPE agus na riatanasan tagraidh aige.
2.1.1 Lòin/Dathan.
Is e pigmentan/dathan na prìomh phàirtean a bheir dath dha TPEn, cunntasachd airson 10%-70% den sgrìobhadh masterbatch (a rèir dèinead dath agus seòrsa TPE). Is e na prìomh riatanasan airson pigmentan / dathan ann am masterbatch TPE:
- – Frith-aghaidh teas: Feumaidh iad seasamh ri teòthachd giollachd an targaid TPE (150℃-290 ℃) gun lobhadh no dath air. Airson TPE aig teòthachd àrd (TPC, TPA), Is fheàrr pigmentan organach àrd-teodhachd no pigmentan neo-organach.
- – Co-fhreagarrachd: Feumaidh a bhith co-chòrdail ris a’ mhaitrix TPE gus imrich a sheachnadh, fo bhlàth, no elasticity nas lugha. Tha pigmentan le polarity coltach ris an TPE nas freagarraiche (m.e., pigmentan polar airson TPU, pigmentan neo-polar airson TPS).
- – Dispersibility: Feumar a bhith air a sgapadh gu furasta anns a’ mhaitrix TPE gus dèanamh cinnteach à dath èideadh agus gus spotan dath a sheachnadh, sreathan, no nas lugha de fheartan meacanaigeach. Pigmentan mìn (20-40 mogal) Is fheàrr le cruinneachadh ìosal.
- – Càirdeas àrainneachdail: Feumaidh coinneachadh ri inbhean dìon àrainneachd cruinneil (leithid REACH, RoHS) gus stuthan puinnseanta no cronail a sheachnadh (leithid meatailtean trom) a dh’ fhaodadh buaidh a thoirt air slàinte dhaoine agus an àrainneachd.
Am measg nam pigmentan cumanta a thathas a’ cleachdadh ann am masterbatch TPE tha: pigmentan neo-organach (titanium dà-ogsaid airson geal, carbon dubh airson dubh, iarann ocsaid airson dearg/buidhe), agus pigmentan organach àrd-teòthachd (phthalocyanine gorm / uaine, quinacridone dearg).
2.1.2 Luchd-giùlain.
Is e luchd-giùlan am matrix den masterbatch, cunntasachd airson 20%-80% den sgrìobhadh, agus tha prìomh phàirt aca ann a bhith a’ sgapadh pigmentan agus a’ cumail ri matrix TPE. Feumaidh co-chòrdalachd sàr-mhath a bhith aig an neach-giùlan leis an dà chuid na pigmentan agus an targaid TPE, oir faodaidh droch cho-chòrdalachd leantainn gu imrich pigment, dath neo-chothromach, agus lùghdachadh ann an coileanadh TPE. Tha taghadh an neach-giùlain stèidhichte air an t-seòrsa TPE:
- – Airson TPS (SBS, SEBS): Cleachd TPS no PP mar an neach-giùlain, aig a bheil co-chòrdalachd math agus fluidity giollachd.
- – Airson TPO/TPE-o: Cleachd PP no PE mar an neach-giùlain, a’ maidseadh co-phàirt polyolefin den TPO.
- – Airson TPV/TPE-v: Cleachd PP mar an neach-giùlain, a tha co-chòrdail ri matrix PP an TPV.
- – Airson TPU: Cleachd TPU mar an neach-giùlain, a’ dèanamh cinnteach à co-chòrdalachd le matrix TPU agus a’ seachnadh hydrolysis.
- – Airson TPC/TPE-E agus TPA/TPE-A: Cleachd TPC no TPA mar an neach-giùlain, fa leth, gus a bhith a rèir riatanasan giollachd àrd-teòthachd agus co-chòrdalachd.
Bu chòir gum biodh fileantachd giullachd math aig an neach-giùlain cuideachd, with a melting point and processing temperature consistent with or slightly lower than the target TPE, to ensure uniform mixing and avoid TPE degradation.
2.1.3 Cur-ris.
Additives are auxiliary components added to improve the processing performance, dispersibility, and functional performance of TPE masterbatch, cunntasachd airson 1%-10% den sgrìobhadh. The type and dosage of additives are determined by the TPE type and application requirements:
- – Dispersants: The most important additive for TPE masterbatch, used to reduce pigment surface tension, prevent agglomeration, and ensure uniform dispersion in the TPE matrix. Common dispersants include polyethylene wax, polypropylene wax, stearic acid, and maleic anhydride grafted waxes. For high-viscosity TPEs (VAT, TPC), high-efficiency dispersants with strong compatibility are preferred.
- – Compatibilizers: Used to improve compatibility between pigments and TPEs, and between masterbatch and TPE matrix. Mar eisimpleir, maleic anhydride grafted PP is used as a compatibilizer for TPO masterbatch, and polyurethane wax is used for TPU masterbatch.
- – Heat Stabilizers: Used to prevent pigment decomposition and TPE degradation during high-temperature processing. Common heat stabilizers include organic tin stabilizers (for TPU), hindered phenol antioxidants (for TPS, TPO), and phosphite antioxidants (for TPC, TPA).
- – UV Stabilizers and Antioxidants: Used to improve the weather resistance and aging resistance of colored TPE products, preventing color fading and performance degradation under sunlight and oxygen. For outdoor applications (such as automotive exterior parts), UV absorbers and hindered amine light stabilizers (HALS) are added.
- – Bealaidh: Used to reduce friction between materials and extrusion equipment (sgread, baraille, ceann bàs), leasachadh fluidity giollachd, agus seachain stuth a’ cumail ri uidheamachd. Tha bealaidh cumanta a’ toirt a-steach searbhag stearic, stearate calcium, agus ola silicone. Airson TPU agus TPA, Is fheàrr leann le imrich ìosal gus nach toir e buaidh air coileanadh toraidh.
- – Cur-ris gnìomhach: Air a chur ris gus gnìomhan sònraichte a thoirt do TPEn, leithid lasraichean-aghaidh (airson uèirichean agus càbaill), riochdairean antistatic (airson co-phàirtean dealain), agus riochdairean antibacterial (airson innealan meidigeach agus bathar luchd-cleachdaidh).
2.2 Prionnsabalan cruthachadh TPE Masterbatch
Feumaidh cruthachadh masterbatch TPE buaidh dath a chothromachadh, coileanadh giollachd, agus feartan gnèitheach TPE. Tha na prìomh phrionnsabalan mar a leanas:
2.2.1 Co-fhreagarrachd an toiseach.
An neach-giùlain, pigmentan, agus feumaidh stuthan cur-ris a bhith co-chòrdail ris an targaid TPE gus nach lughdaich e elasticity an stuth, sùbailteachd, agus feartan meacanaigeach. Mar eisimpleir, Le bhith a’ cleachdadh inneal-giùlain neo-polar airson TPU polar thig droch cho-chòrdalachd agus imrich pigment.
2.2.2 Match Resistance Teas.
The pigments and additives must have heat resistance matching the TPE processing temperature. Mar eisimpleir, TPC masterbatch uses high-temperature resistant pigments (heat resistance ≥280℃) to avoid decomposition during processing.
2.2.3 Optimize Dispersibility.
The pigment content and dispersant dosage are adjusted to ensure uniform dispersion. High-concentration masterbatch (pigment content 50%-70%) requires more dispersants and better mixing capabilities, while low-concentration masterbatch (10%-30%) focuses on compatibility.
2.2.4 Minimize Impact on TPE Properties.
The masterbatch should not significantly affect the TPE’s elasticity, compression set, or abrasion resistance. Mar eisimpleir, excessive dispersants or lubricants may reduce the TPE’s mechanical strength.
2.2.5 Environmental Protection Compliance.
The formulation must meet global environmental protection standards, avoiding toxic or harmful substances (leithid meatailtean trom, phthalates) that could restrict market access.
2.3 Processing Requirements of TPE Masterbatch
TPE masterbatch processing is mainly carried out using twin-screw extrusion technology, which requires strict control of raw material pretreatment, premixing, extrusion parameters, and post-processing to ensure product quality. The key processing requirements are as follows:
2.3.1 Pretreatment Stuth Raw.
TPEs (especially TPU, TPA) tha sùghadh uisge àrd aca, so all raw materials (TPE carrier, pigmentan, stuthan cur-ris) feumar a bhith air a thiormachadh gu mionaideach mus tèid a ghiollachd. The drying temperature and time are determined by the material type: TPU/TPA is dried at 100-120℃ for 6-8 uairean, TPS/TPO is dried at 80-100℃ for 3-5 uairean, and pigments are dried at 60-80℃ for 2-4 uairean. The moisture content of dried raw materials should be controlled below 0.1% (0.05% for TPU/TPA).
A bharrachd air, pigments with large particle sizes or agglomerates should be crushed and sieved (20-40 mogal) gus sgaoileadh a leasachadh, agus neo-thruaillidheachd (mìrean meatailt, duslach) bu chòir a thoirt air falbh gus caitheamh air uidheamachd eas-tharraing agus uireasbhaidhean ann am masterbatch a sheachnadh.
2.3.2 Premixing.
Na stuthan amh tioram (pigmentan, neach-giùlain, stuthan cur-ris) air am measgachadh ann am measgadair àrd-astar a rèir co-mheas na foirmle gus measgachadh tòiseachaidh èideadh a chruthachadh. Tha na paramadairean premixing air an atharrachadh a rèir an seòrsa TPE: astar measgachadh 800-1200 rpm, measgachadh ùine 5-10 mionaidean, teòthachd measgachadh 40-60 ℃. Airson masterbatch àrd-dùmhlachd no luchd-giùlan TPE àrd-slaodachd, tha an ùine premixing air a leudachadh, agus bidh luchd-sgaoilidh air an cur ris an toiseach gus na pigmentan a chòmhdach, a' leasachadh sgapadh.
2.3.3 Smachd Parameters Extrusion.
Is e eas-tharraing dà-sgriubha am prìomh cheum ann an giullachd TPE masterbatch, agus na prìomh pharaimearan (teòthachd, astar sgriubha, cuideam eas-tharraing, astar beathachaidh) feumar smachd mionaideach a chumail air an t-seòrsa TPE:
- – Smachd Teòthachd: Tha am baraille air a roinn na 4-6 earrannan smachd teothachd (roinn beathachaidh, earrann leaghaidh, earrann measgachadh, roinn homogenizing, roinn ceann bàs). The temperature of each section is adjusted according to the TPE processing temperature. Mar eisimpleir, 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.
- – Luas sgriubha: 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.
- – Extrusion Brùthadh: 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. For high-viscosity TPEs, 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 (particle size 2-5mm), screened (to remove unqualified particles), and packaged (sealed and moisture-proof packaging). For moisture-sensitive TPE masterbatch (TPU, TPA), the finished product is dried again before packaging to prevent moisture absorption.
