1. O prezentare generală a elastomerilor termoplastici (TPE-uri)
Elastomeri termoplastici (TPE-uri), uneori denumite cauciucuri termoplastice (TPR-uri), sunt o familie diversă de materiale care prezintă caracteristicile duale ale termoplasticului și elastomerilor. Spre deosebire de cauciucurile tradiționale reticulate, care sunt infuzibile şi insolubile odată vindecate, TPE-urile pot fi topite și reprocesate folosind metode standard de prelucrare a materialelor termoplastice, cum ar fi extrudarea, turnare prin injecție, și suflare, menținând în același timp o excelentă recuperare elastică și flexibilitate la temperatura camerei. Această dualitate unică provine din structura lor moleculară: TPE-urile sunt de obicei fie copolimeri (polimeri formați din două sau mai multe unități monomerice diferite) sau amestecuri fizice de o componentă din plastic și o componentă de cauciuc, unde faza plastică formează o matrice continuă care se înmoaie și curge la încălzire, iar faza de cauciuc oferă elasticitate și rezistență.
Avantajele cheie ale TPE-urilor față de cauciucurile și materialele plastice convenționale au determinat adoptarea lor pe scară largă în producția modernă.. Aceste avantaje includ: procesabilitate excelentă (permițând producție de mare viteză și geometrii complexe ale pieselor), reciclabilitate (reducerea deșeurilor materiale și a impactului asupra mediului), rezistență chimică bună, proprietăți mecanice superioare (cum ar fi rezistența la tracțiune, alungirea la rupere, si rezistenta la abraziune), și capacitatea de a fi colorat, texturat, sau modificate pentru a îndeplini cerințele specifice aplicației. În plus, TPE-urile oferă economii de costuri în producție datorită timpilor de ciclu mai scurti, consum redus de energie, și eliminarea etapelor de întărire necesare pentru cauciucurile tradiționale.
Ca cererea de ușoare, durabil, iar materialele durabile continuă să crească, TPE-urile au devenit din ce în ce mai importante în industrii precum cea auto (pentru ușurare și reducerea zgomotului), electronice (pentru componente flexibile și durabile), și bunuri de larg consum (pentru produse confortabile și ergonomice). Pentru a valorifica pe deplin beneficiile TPE, producătorii au nevoie de echipamente de procesare care să poată face față provocărilor unice ale acestor materiale, inclusiv sensibilitatea lor la temperatură, rata de forfecare, și uniformitatea amestecării.

2. Cele șase categorii generale de TPE comerciale
TPE-urile comerciale sunt clasificate în șase categorii principale în funcție de compoziția lor chimică, structura moleculara, și caracteristicile de performanță. Fiecare categorie are proprietăți unice care o fac potrivită pentru aplicații specifice, și seria de extrudere Zhuoyue sunt proiectate pentru a face față cerințelor de procesare ale fiecărui tip, asigurând rezultate optime de amestecare. Mai jos este o prezentare detaliată a fiecărei categorii, inclusiv structura lor, proprietăți, și aplicații tipice:
2.1 Copolimeri bloc stireni (TPS, TPE-uri)
Copolimeri bloc stireni (TPS), cunoscut și sub denumirea de TPE-s, sunt cea mai utilizată și versatilă categorie de TPE, reprezentând o cotă semnificativă din piața globală de TPE. Sunt compuse din blocuri alternante de stiren (un monomer termoplastic rigid) și o dienă (un monomer elastomeric flexibil), de obicei butadienă, izopren, sau derivații lor hidrogenați. Cele mai comune tipuri de TPS includ Stiren-Butadienă-Stiren (SBS), Stiren-Izopren-Stiren (SIS), SBS hidrogenat (SEBS), și SIS hidrogenat (SEPS).
Structura bloc unică a TPS le conferă proprietățile lor caracteristice: blocurile de stiren se formează greu, domenii sticloase la temperatura camerei care acționează ca legături încrucișate fizice, oferind rezistență mecanică și stabilitate a formei, în timp ce blocurile diene se formează moi, domenii cauciucate care conferă elasticitate și flexibilitate. Când este încălzit peste temperatura de tranziție sticloasă a blocurilor de stiren (de obicei, în jur de 100°C), domeniile dure se înmoaie și curg, permițând ca materialul să fie prelucrat ca un termoplastic; când este răcită, domeniile dure se reformează, restabilirea proprietăților elastomerice.
Proprietățile cheie ale TPS includ flexibilitate excelentă, rezistență bună la tracțiune, densitate scăzută, procesabilitate superioară, și compatibilitate cu o gamă largă de aditivi (precum plastifianții, umpluturi, și stabilizatori). De asemenea, prezintă o rezistență bună la apă, uleiuri, și substanțe chimice, deși TPS hidrogenat (SEBS, SEPS) oferă o rezistență îmbunătățită la oxidare și căldură în comparație cu tipurile nehidrogenate (SBS, SIS).
Aplicațiile tipice ale TPS includ: componente auto (burlane, garniturile usii, ornamente de bord, si amortizoare), bunuri de consum (jucării, prinderi, mânere, și tălpi de încălțăminte), dispozitive medicale (tubulatura cateterului, piston de seringă, și sigilii medicale), și adezivi și etanșanți (adezivi topibili la cald, adezivi sensibili la presiune). Extruderele lui Zhuoyue sunt optimizate pentru procesarea TPS, cu control precis al temperaturii și capacități eficiente de amestecare pentru a asigura o dispersie uniformă a aditivilor și proprietăți consistente ale materialului.
2.2 Elastomeri poliolefinici termoplastici (TPO, TPE-o)
Elastomeri poliolefinici termoplastici (TPO), sau TPE-o, sunt amestecuri fizice ale unei poliolefine (de obicei polipropilenă, PP) și un elastomer (de obicei monomer etilen-propilen-dienă, EPDM). Spre deosebire de TPS, care sunt copolimeri, TPO-urile sunt amestecuri eterogene în care poliolefina formează o matrice continuă, iar elastomerul formează domenii cauciucate discrete. Proprietățile TPO pot fi adaptate prin ajustarea raportului dintre poliolefină și elastomer, precum și tipul și cantitatea de aditivi (precum materiale de umplutură, antioxidanti, și stabilizatori UV).
TPO-urile oferă o combinație unică de proprietăți, inclusiv rezistență excelentă la intemperii, rezistență chimică bună (mai ales la acizi, bazele, si alcooli), densitate scăzută, rezistență ridicată la impact, și procesabilitate bună. Ele sunt, de asemenea, rentabile în comparație cu alte categorii de TPE, făcându-le o alegere populară pentru aplicații de volum mare. În plus, TPO-urile sunt reciclabile și pot fi amestecate cu alte poliolefine pentru a îmbunătăți performanța sau a reduce costurile.
Unul dintre avantajele cheie ale TPO este rezistența lor excelentă la radiațiile UV și la ozon, ceea ce le face ideale pentru aplicații în aer liber.

2.3 Vulcanizate termoplastice (CUVĂ, TPE v)
Vulcanizate termoplastice (CUVĂ), cunoscut și ca TPE-v, sunt un subset de TPO care suferă un proces de vulcanizare dinamică în timpul combinării. Vulcanizarea dinamică implică încălzirea amestecului de poliolefină și elastomer la o temperatură peste punctul de topire al poliolefinei, în timp ce se adaugă simultan un agent de vulcanizare (cum ar fi sulful sau peroxidul) pentru a reticula faza elastomerului. Rezultatul este un material în care faza de elastomer este complet reticulat (vulcanizat) în particule discrete, dispersat într-o matrice continuă de poliolefină.
Procesul de vulcanizare dinamică conferă TPV-urilor proprietăți superioare în comparație cu TPO-urile convenționale, inclusiv o elasticitate mai mare, rezistență la compresie mai bună, rezistență la tracțiune îmbunătățită, și rezistență sporită la căldură, uleiuri, și substanțe chimice.
