Note: Izinto ze-TPE zingahlulwa zibe ziindidi ezininzi.

I-Thermoplastic Elastomer (TPE) yipolymer e-elastic eneempawu zoomatshini ezinxulumene ikakhulu nobunzima bezinto ngokwazo (ukusuka kwiNxweme A ukuya kwiNxweme D) kunye neempawu zayo kwiindawo ezahlukeneyo okanye iimeko zokusebenza. Izinto ze-TPE zingahlulwa zibe ziindidi ezininzi.


1. Ibhloko le-Polyether amide (PEBA)
I-elastomer ephambili ye-polyamide eneepropathi ezilungileyo ezinje ngothamba, ubhetyebhetye, ukubuyela kwimeko yesiqhelo kubushushu obuphantsi, ukumelana ne-abrasion kunye nokumelana neekhemikhali. Ilungele usetyenziso kwiimveliso zobugcisa obuphezulu.


2.Istabha se-thermoplastic rubber (SBS, SEBS)
I-polymer ye-styrenic thermoplastic polymer. I-SBS kunye ne-SEBS elastomers zihlala zisetyenziselwa ukuvelisa iimveliso ezahlukeneyo ezifuna ukuqina, ukuthamba okuthambileyo kunye nobuhle. Zilungele ukusetyenziswa kwimixube yesiko eyilelwe iimveliso ezithile. Xa kuthelekiswa ne-SBS, i-SEBS isebenza ngcono kwizicelo ezithile ezithile kuba iyamelana ngcono ne-oxidation yemitha ye-ultraviolet, kwaye iqondo layo lokusebenza linokufikelela kwi-120 ° C; I-SEBS inokugqithiswa kunye ne-thermoplastic (i-PP, i-SAN, i-PS, i-ABS, i-PC-ABS, i-PMMA, i-PA) ixutywe ukufezekisa iimfuno zoyilo lobugcisa okanye ukusebenza.


3. I-Thermoplastic polyurethane (TPU)
Yipolymer yepholiyesta (ipholiyesta ye-TPU) kunye ne-polyether (i-polyether TPU) yeentsapho. Yinto elastomer kunye nokumelana iinyembezi eliphezulu, ukumelana lingonakali kunye nokumelana cut. ). Ubunzima bemveliso bunokuvela kwi-70A ukuya kwi-70D Shore. Ukongeza, i-TPU inokomelela ngokugqwesileyo kwaye inokugcina iimpawu ezintle nangaphantsi kwamaqondo obushushu aphezulu.


4.I-Thermoplastic vulcanizate (TPV)
Ukwenziwa kwepolymer kubandakanya i-elastomer irabha eyenziwe ngerabha (okanye irabha enqamlezileyo). Le nkqubo ye-vulcanization / ye-crosslinking yenza ukuba i-TPV ibe ne-thermoplasticity egqwesileyo, ukuqina kunye nokuguquguquka.
