Thermoplastic Rubber-TPR, tseem hu ua Thermoplastic Elastomer (TPE), yog cov khoom siv sib xyaw ua ke ntawm cov roj hmab thiab cov thermoplastics. Thermoplastic elastomers muaj ntau yam kev teeb tsa. Qhov tseem ceeb tshaj plaws yog qhov yuav tsum tau muaj tsawg kawg yog ob qho kev sib koom ua ke ntawm cov txheej txheem polymer. Ntawm qhov kub ntawm kev siv ib txwm, ib theem yog cov kua dej (ua kom kub siab tshaj nws Tg-iav hloov kub). Lwm theem yog ib qho khoom (kom qhov kub thiab txias qis dua nws Tg lossis sib npaug rau Tg) thiab muaj kev cuam tshuam ntawm ob theem. Ntawd yog, nws nthuav tawm cov roj hmab elasticity ntawm qhov kub thiab txias, thiab tuaj yeem ua plasticized thiab tsim rau hauv cov khoom siv polymer ntawm qhov kub thiab txias. Nws muaj cov khoom siv kho tshuab thiab kev ua haujlwm zoo ib yam li roj hmab, thiab tuaj yeem ua tiav thiab rov zoo raws li cov thermoplastics. Nws yog tsim los ntawm cov yas thiab roj hmab. ib tug choj. Yog li, thermoplastic elastomers tuaj yeem ua cov khoom siv roj hmab kom sai, ua tau zoo, thiab kev lag luam zoo li cov thermoplastics. Hais txog kev ua, nws yog ib hom yas; nyob rau hauv cov nqe lus ntawm xwm, nws yog ib hom roj hmab. Thermoplastic elastomers muaj ntau yam zoo dua cov roj hmab thermoset.
