TPV
Thermoplastic vulcanizate (English as Thermoplastic Vulcanizate), referred to as TPV, thermoplastic
vulcanizate in Chinese referred to as thermoplastic rubber (English Thermoplastic Rubber), referred
to as TPR, but this name is easy to be confused with other types of thermoplastic elastomers
(Thermoplastic Elastomer in English) Together, because thermoplastic elastomers are usually called
thermoplastic rubbers, especially styrene elastomers, at least in China, it seems that "TPR" has
become its proper name. When it comes to TPR, it refers to SBS, SEBS, etc. Styrenic elastomers are
thermoplastic elastomers as base materials, which are inseparable from the large consumption of
styrenic elastomers in the fields of civil and final consumer goods. TPV is mainly composed of two
parts, one is plastic as a continuous phase, and the other is rubber as a dispersed phase. Usually
rubber needs to be combined with softening oil or plasticizer. Vulcanizing agent and some auxiliary
additives are also essential. In addition, some inorganic fillers will be added in order to reduce costs
or improve performance in certain aspects.
