Thermoplastic Elastomer (TPE) ndi polima yotanuka yomwe makina ake amakhudzana kwambiri ndi kuuma kwa zinthu zomwezo (kuyambira ku Gombe A mpaka ku Gombe D) ndi mawonekedwe ake m'malo osiyanasiyana kapena momwe amagwirira ntchito. Zipangizo za TPE zitha kugawidwa m'mitundu yambiri.
1. Polyether chipika amide (PEBA)
Ndi zotsogola polyamide elastomer yokhala ndi zinthu zabwino monga kusinthasintha, kusinthasintha, kutentha pang'ono, kukana kumva kuwawa ndi kukana mankhwala. Oyenera ofunsira mankhwala zina zamakono.
2. Styrene thermoplastic mphira (SBS, SEBS)
Ndi styrenic thermoplastic polima. SBS ndi SEBS elastomers amagwiritsidwa ntchito kwambiri popanga zinthu zosiyanasiyana zomwe zimafunikira kukhathamira, kukhudza kosavuta komanso kukongoletsa. Ndizoyenera kugwiritsidwa ntchito popanga makina omwe amapangidwira zinthu zina. Poyerekeza ndi SBS, SEBS imagwira bwino ntchito zina chifukwa imakana bwino makutidwe ndi cheza cha ultraviolet, ndipo kutentha kwake kogwira ntchito kumatha kufika 120 ° C; SEBS itha kugonjetsedwa ndipo thermoplastic (PP, SAN, PS, ABS, PC-ABS, PMMA, PA) imasakanizidwa kuti ikwaniritse zofunikira pakapangidwe kazokongoletsa kapena magwiridwe antchito.
3. Thermoplastic polyurethane (TPU)
Ndi polima ya polyester (polyester TPU) ndi polyether (polyether TPU) mabanja. Ndi elastomer wokhala ndi kulira kwakukulu, kukana kumva kuwawa ndi kukana. ). Kuuma kwa mankhwala kumatha kukhala kuchokera ku 70A mpaka 70D Shore. Kuphatikiza apo, TPU imakhala yolimba kwambiri ndipo imatha kukhalabe ndi makhalidwe abwino ngakhale kutentha kwambiri.
4. Thermoplastic vulcanizate (TPV)
Zomwe zimapangidwira zimaphatikizapo mphira wa elastomer (kapena mphira wolumikizidwa wopingasa). Njira yolumikizira / yolumikizayi imapangitsa TPV kukhala ndi kutentha kwambiri, kusinthasintha komanso kusinthasintha.
