TPE
Thermoplastic elastomer, referred to as TPE or TPR, is the abbreviation of Thermoplastic rubber. It is a kind of
elastomer that has the elasticity of rubber at room temperature and can be plasticized at high temperature. The
structural feature of thermoplastic elastomers is that different resin segments and rubber segments are composed of
chemical bonds. The resin segment forms physical cross-linking points by virtue of interchain force, and the rubber
segment is a highly elastic segment that contributes to elasticity. The physical crosslinking of the plastic segments is
reversible with temperature, showing the plastic processing properties of thermoplastic elastomers. Therefore,
thermoplastic elastomer has the physical and mechanical properties of vulcanized rubber and the processing
properties of thermoplastics. It is a new type of polymer material between rubber and resin, and is often referred to as
the third-generation rubber. Thermoplastic elastomer is a new type of polymer material between rubber and resin,
which can not only replace part of rubber, but also modify plastic. Thermoplastic elastomers have the dual properties
and broad characteristics of rubber and plastic, so that they are widely used in the rubber industry to manufacture
rubber shoes, tapes and other daily necessities and rubber hoses, tapes, rubber strips, rubber sheets, plastic parts and
adhesives, etc. Various industrial supplies. At the same time, thermoplastic elastomers can also be widely used in the
modification of general thermoplastic resins such as PVC, PE, PP, PS, and even engineering plastics such as PU, PA,
and CA, instead of rubber, which has brought a new situation to the plastics industry.
