ʻO TPR kahi ʻano polymer palupalu me nā waiwai modulation.E like me nā koi like ʻole o nā mea kūʻai aku, hāʻawi nā mea hoʻolako i ka TPE a me ka TPR material formula system a me nā hoʻonā noi.He mea koʻikoʻi ka ikaika o ka mana R&D e loiloi i ka ikaika piha o nā mea hana TPE a me TPR.
No ke aha ka nui o nā mea hana pāʻani holoholona e koho i ka mea TPE ma kahi o ka mea PVC, ʻo ka mea mua ka pale ʻana i ke kaiapuni.ʻAʻole loaʻa i ka TPE a me ka TPR ka phthalate plasticizer a me ka halogen, a ʻo ka puhi ʻana o TPE a me TPR ʻaʻole hoʻokuʻu i ka dioxin a me nā mea ʻino ʻē aʻe.
No ka paʻakikī o nā mea pāʻani holoholona, ʻo ka ʻāpana paʻakikī o PVC he p (i hōʻike ʻia e ka mea o ka plasticizer), a ʻo ka ʻāpana paʻakikī o TPE a me TPR he (ana ʻia e ka ʻikepili i ana ʻia e ka mea hōʻike paʻakikī kahakai a).P a me a, ʻelua ʻano paʻakikī, loaʻa kahi pilina hoʻololi.
ʻO ka mea maʻamau, ʻoi aku ka maikaʻi o ka wai o TPE a me TPR ma mua o ka PVC.ʻOi aku ka kiʻekiʻe o ka plasticizing a me ka hoʻoheheʻe ʻana o ka TPE a me ka TPR ma mua o ka PVC (TPE, TPR plasticizing wela ʻo 130 ~ 220 ℃, PVC plasticizing wela he 110 ~ 180 ℃);ʻO ka mea maʻamau, ʻo ka shrinkage o PVC palupalu he 0.8 ~ 1.3%, ʻo TPE a me TPR he 1.2 ~ 2.0%.
ʻOi aku ka maikaʻi o ka pale wela haʻahaʻa o TPE a me TPR ma mua o PVC.ʻAʻole paʻakikī ʻo TPE a me TPR ma - 40 ℃ a e paʻakikī ka PVC ma - 10 ℃.
Hiki ke hoʻoheheʻe ʻia ʻo TPE a me TPR no nā mea pāʻani holoholona e ka hoʻoheheʻe ʻana, extrusion a me ka hoʻoheheʻe ʻana, ʻoiai ʻo PVC hiki ke hoʻoheheʻe ʻia e ka injection, extrusion, lining a me ka hāʻule ʻana.
