Thermoplastic elastomers TPR resin have a variety of possible structures. The most fundamental one is that there are at least two mutually dispersed polymer phases. Under normal use temperature, one phase is a fluid (making the temperature higher than its Tg-glass transition temperature) The other phase is solid (the temperature is lower than its Tg or equal to Tg), and there is an interaction between the two phases. That is, a polymer material that shows rubber elasticity at normal temperature and can be plasticized at high temperature. It has mechanical properties and performance similar to rubber, and can be processed and recycled as a thermoplastic. It is built between plastic and rubber. A bridge. Therefore, thermoplastic elastomers can process rubber products as quickly, efficiently, and economically as thermoplastics. In terms of processing, it is a plastic; in terms of nature, it is also a rubber. Thermoplastic elastomers have many advantages over thermosetting rubber. Elastomer is a kind of artificial thermoplastic elastomer with unique properties, which has a very wide range of uses. TPR resin's excellent product applicability comes from the adjustability and controllability of its special molecular structure, thus showing the following excellent performance: Excellent physical properties: good appearance texture, mild touch, easy to color, uniform color tone, stable ; Adjustable physical properties provide a wide product design space; Mechanical properties are comparable to vulcanized rubber, but no vulcanization cross-linking; Wide hardness range, adjustable from SHORE-A 0 degrees to SHORE-D 70 degrees; Excellent tensile resistance, resistance The tensile strength can be up to a dozen Mpa, and the elongation at break can be up to more than ten times; the long-term temperature resistance can exceed 70 ℃, the low temperature environment performance is good, and it can still maintain good flexure at -60 ℃ temperature; good The electrical insulation and voltage resistance characteristics. It has outstanding anti-skid performance, abrasion resistance and weather resistance performance □ superior chemical properties and resistance to general chemicals (water, acid, alkali, alcohol solvents); can be processed in a solvent, can be immersed in a solvent or oil for a short time; non-toxic; Good anti-ultraviolet radiation and anti-oxidation performance of TPR resin can be used in outdoor environment; good adhesion performance, suitable adhesive technology can be directly adhered to the surface of synthetic leather or artificial leather.
