Thermoplastic Elastomer (TPE) waa polymer laastik ah oo aaladaha farsamaysan ay inta badan la xiriiraan adkaanta maaddada lafteeda (oo ka bilaabata Shore A ilaa Shore D) iyo astaamaha ay ku leedahay deegaanno kala duwan ama xaalado shaqo. Qalabka TPE waxaa loo qaybin karaa noocyo badan.


1. Polyether block amide (PEBA)
Waa elastomer polyamide horumarsan oo leh sifooyin wanaagsan sida dabacsanaanta, dabacsanaanta, soo kabashada heerkulka hooseeya, iska caabinta abrasionka iyo iska caabinta kiimikada. Ku habboon codsiyada alaabada tiknoolajiyada sare.


2. Caag kuleylka kuleylka leh (SBS, SEBS)
Waa polymer heerkulbeeg leh oo heerkulbeeg leh. SBS iyo SEBS elastomers ayaa inta badan loo isticmaalaa in lagu soo saaro badeecooyin kala duwan oo u baahan dabacsanaan, taabasho jilicsan iyo qurux. Waxay ku habboon yihiin in loo isticmaalo qaabab u gaar ah oo loogu talagalay alaabooyin gaar ah. Marka loo barbardhigo SBS, SEBS waxay sifiican ugu shaqeysaa codsiyada qaaska ah maxaa yeelay waxay sifiican uga hortageysaa oksijiinta shucaaca 'ultraviolet rays', heerkulkeeduna wuxuu xitaa gaari karaa 120 ° C; SEBS waa la dhaafi karaa oo heerkulbeegga (PP, SAN, PS, ABS, PC-ABS, PMMA, PA) waa la isku qasan yahay si loo buuxiyo shuruudaha naqshadeynta qurxinta ama shaqeynta.


3. Polyurethane kuleylka leh (TPU)
Waa polymer ka tirsan polyesterka (polyester TPU) iyo polyether (polyether TPU) qoysaska. Waa elastomer leh iska caabin ilmo sare leh, iska caabin abrasion iyo iska caabin la gooyey. ). Adkaanta badeecaddu waxay u dhaxeysaa 70A ilaa 70D Shore. Intaa waxaa dheer, TPU waxay leedahay adkeysi aad u fiican waxayna ilaalin kartaa astaamo wanaagsan xitaa heerkulka ba'an.


4. Dumarka kuleylka kuleylka leh (TPV)
Waxyaabaha ay ka kooban tahay polymer-ka waxaa ka mid ah caag elastomer ah oo jilicsan (ama caag iskutallaabta oo isku xiran). Nidaamkan foosha xun / iskutallaabta ayaa ka dhigaysa TPV inay leedahay heer-kul-kulmeed heer sare ah, dabacsanaan iyo dabacsanaan.
