TPV feem ntau muaj ob yam: ib theem yas, uas ua hauj lwm raws li cov matrix tas mus li, thiab cov roj hmab theem, uas ua raws li cov theem dispersed. Feem ntau, cov khoom siv roj hmab yuav tsum tau sib xyaw nrog cov roj softening lossis plasticizer. Curing agents thiab ntau yam auxiliary additives kuj tseem yog qhov tseem ceeb. Tsis tas li ntawd, txhawm rau txo cov nqi lossis txhim kho cov yam ntxwv ntawm kev ua tau zoo, inorganic fillers feem ntau suav nrog.
Thaum TPVs tuaj yeem ua raws li kev xav tau tsim los ntawm ntau hom yas thiab roj hmab sib xyaw ua ke, tsuas yog xaiv ob peb qhov sib xyaws -tshwj xeeb yog cov uas raug rau cov vulcanization dynamic - muaj cov khoom siv siv tau. Cov piv txwv muaj xws li PP/PE/EPDM, PP/NBR, PP/ACM, thiab PS/SEBS. Nyob rau hauv phau ntawv *Thermoplastic Elastomers* (tshaj tawm los ntawm Chemical Industry Press), ib qho kev tshuaj ntsuam xyuas tau ua tiav ntawm 99 qhov sib txawv ntawm cov roj hmab / yas sib xyaw los ntawm 11 hom roj hmab sib txawv thiab 9 hom yas. Kev tshawb fawb xaus tias kom ua tiav cov roj hmab dynamically vulcanized / thermoplastic sib xyaw nrog kev ua haujlwm zoo, cov xwm txheej hauv qab no yuav tsum tau ua raws: (1) lub zog saum npoo ntawm ob lub polymer cov khoom - cov yas thiab cov roj hmab - yuav tsum tau sib xws; (2) cov roj hmab tivthaiv yuav tsum muaj qhov luv luv molecular saw entanglement ntev; thiab (3) lub crystallinity ntawm cov yas yuav tsum tshaj 15%. Nyob rau hauv cov xwm txheej uas muaj qhov sib txawv tseem ceeb hauv polarity lossis lub zog saum npoo ntawm cov khoom yas thiab roj hmab, kev sib koom ua ke ntawm cov khoom sib xyaw tsim nyog ua ntej dynamic vulcanization tuaj yeem ua rau cov khoom sib xyaw ua kom pom cov khoom zoo heev.
