Thermoplastic Elastomer (TPE) bụ polymer na-agbanwe agbanwe nke njirimara ya bụ nke metụtara nrụgide nke ihe ahụ n'onwe ya (sitere na Shore A ruo Shore D) yana njirimara ya na gburugburu ebe dị iche iche ma ọ bụ ọnọdụ ọrụ. Enwere ike ịkekọrịta ihe TPE n'ọtụtụ ụdị.
1. Polyether ngọngọ amide (PEBA)
Ọ bụ elastomer polyamide dị elu nwere ezigbo ihe onwunwe dị ka elasticity, mgbanwe, mgbake okpomọkụ dị ala, nkwụsị abrasion na nguzogide kemịkal. Kwesịrị ekwesị maka ngwa dị na ngwaahịa ọgbara ọhụrụ.
2. Styrene thermoplastic roba (SBS, SEBS)
Ọ bụ styrenic thermoplastic polymer. A na-ejikarị SBS na SEBS elastomers emepụta ngwaahịa dị iche iche chọrọ nro, mmetụ dị nro na aesthetics. Ha na-adabara ojiji na omenala formulations mere maka kpọmkwem ngwaahịa. N'iji ya tụnyere SBS, SEBS na-arụ ọrụ nke ọma na ụfọdụ ngwa ụfọdụ akọwapụtara n'ihi na ọ ka mma na-eguzogide oxidation nke ụzarị ultraviolet, na ọnọdụ ọrụ ya nwere ike iru 120 Celsius; SEBS nwere ike imeghari ya na thermoplastic (PP, SAN, PS, ABS, PC-ABS, PMMA, PA) iji mezuo ihe ndi choro nke aesthetics ma obu oru.
3. Thermoplastic polyurethane (TPU)
Ọ bụ polima nke ndị polyester (polyester TPU) na ezinụlọ polyether (polyether TPU). Ọ bụ elastomer nwere akwa akwa nguzogide, abrasion eguzogide na bee eguzogide. ). Ikike ngwaahịa ahụ nwere ike ịdị site na 70A ruo 70D Shore. Na mgbakwunye, TPU nwere nnagide magburu onwe ya ma nwee ike ijigide njirimara ọma ọbụlagodi n'okpuru oke okpomọkụ.
4. Thermoplastic vulcanizate (TPV)
Ihe mejupụtara nke polymer gụnyere elastomer vulcanized roba (ma ọ bụ obe-njikọ vulcanized roba). Usoro nkwuputa a / njikọ njikọta na-eme ka TPV nwee ezigbo nrụpụta ọkụ, nrụpụ na mgbanwe.
