TPR yog ib yam ntawm cov mos mos polymer nrog cov khoom ua haujlwm.Raws li cov kev xav tau sib txawv ntawm cov neeg siv khoom, cov neeg muag khoom muab cov phiaj xwm TPE thiab TPR cov qauv txheej txheem thiab cov kev daws teeb meem.Lub zog ntawm R & D muaj peev xwm yog ib qho tseem ceeb rau kev ntsuam xyuas lub zog ntawm TPE thiab TPR manufacturers.
Vim li cas ntau tus tsiaj cov khoom ua si xaiv cov khoom siv TPE es tsis txhob siv cov khoom siv PVC, thawj zaug yog kev tiv thaiv ib puag ncig.TPE thiab TPR tsis muaj phthalate plasticizer thiab halogen, thiab TPE thiab TPR combustion tsis tso tawm dioxin thiab lwm yam khoom tsis zoo.
Rau qhov hardness ntawm cov khoom ua si tsiaj, lub hardness unit ntawm PVC yog p (qhia los ntawm cov ntsiab lus ntawm plasticizer), thiab hardness unit ntawm TPE thiab TPR yog ib tug (tsim los ntawm cov ntaub ntawv ntsuas los ntawm ntug hardness tester a).P thiab a, ob hom hardness, muaj kwv yees li kev hloov dua siab tshiab kev sib raug zoo.
Feem ntau hais lus, fluidity ntawm TPE thiab TPR yog phem dua li ntawm PVC.Lub plasticizing thiab molding kub ntawm TPE thiab TPR yog siab dua li ntawm PVC (TPE, TPR plasticizing kub yog 130 ~ 220 ℃, PVC plasticizing kub yog 110 ~ 180 ℃);Feem ntau hais lus, qhov shrinkage ntawm mos PVC yog 0.8 ~ 1.3%, TPE thiab TPR yog 1.2 ~ 2.0%.
TPE thiab TPR muaj qhov ntsuas kub zoo dua li PVC.TPE thiab TPR yuav tsis tawv ntawm - 40 ℃ thiab PVC yuav harden ntawm - 10 ℃.
TPE thiab TPR rau cov khoom ua si tsiaj tuaj yeem tsim los ntawm kev txhaj tshuaj molding, extrusion thiab tshuab molding, thaum PVC tuaj yeem molded los ntawm kev txhaj tshuaj, extrusion, hauv ob sab phlu thiab xa rov qab.
