I-Thermoplastic Elastomer (TPE) iyi-polymer e-elastic enezici zemishini ezihlobene kakhulu nobulukhuni bento uqobo (kusuka ku-Shore A kuye ku-Shore D) kanye nezimpawu zayo ezindaweni ezihlukile noma ezimeni zokusebenza. Izinto ze-TPE zingahlukaniswa ngezinhlobo eziningi.
1.I-Polyether block amide (i-PEBA)
Kuyi-elastomer esezingeni eliphakeme ye-polyamide enezinto ezinhle ezifana nokuqina, ukuguquguquka, ukululama kwezinga lokushisa okuphansi, ukumelana nomhuzuko nokumelana namakhemikhali. Ifanele izinhlelo zokusebenza kumikhiqizo ephezulu.
2.I-Styrene thermoplastic rubber (SBS, SEBS)
I-polymer ye-styrenic thermoplastic. Ama-elastomers we-SBS ne-SEBS asetshenziswa kakhulu ukukhiqiza imikhiqizo eyahlukahlukene edinga ukuqina, ukuthinta okuthambile nobuhle. Zikulungele ukusetshenziswa ekwakhiweni okwenziwe ngokwezifiso okwenzelwe imikhiqizo ethile. Uma kuqhathaniswa ne-SBS, i-SEBS isebenza kangcono ezinhlelweni ezithile ezithile ngoba imelana kangcono ne-oxidation yemisebe ye-ultraviolet, futhi ukushisa kwayo okusebenzayo kungafinyelela ku-120 ° C; I-SEBS inganqotshwa futhi i-thermoplastic (i-PP, i-SAN, i-PS, i-ABS, i-PC-ABS, i-PMMA, i-PA) ixubene ukuhlangabezana nezidingo zokwakhiwa kobuhle noma ukusebenza.
3.I-Thermoplastic polyurethane (TPU)
I-polymer engeye-polyester (i-polyester TPU) nemindeni ye-polyether (i-polyether TPU). I-elastomer enokumelana okukhulu nezinyembezi, ukumelana nomhuzuko kanye nokumelana nokusika. ). Ubulukhuni bomkhiqizo bungaba kusuka ku-70A kuye ku-70D Shore. Ngaphezu kwalokho, i-TPU inokuqina okuhle kakhulu futhi ingagcina izici ezinhle noma ngaphansi kwamazinga okushisa kakhulu.
4.I-Thermoplastic vulcanizate (TPV)
Ukwakheka kwe-polymer kufaka irabha le-elastomer vulcanized (noma irabha ehlanganisiwe ehlanganiswe). Le nqubo ye-vulcanization / crosslinking yenza i-TPV ibe ne-thermoplasticity enhle kakhulu, ukuqina kanye nokuguquguquka.
