韩国SK TPEE G155D--The development of thermoplastic elastomermaterials is relatively late, so its output is not particularlylarge. However, because the output of thermoplastic materials suchas PVC is very large, and it is also relatively low, it occupies agreat advantage. More importantly, it is difficult to burn. It hasgood corrosion resistance for materials with various chemicalproperties, Therefore, the research on TPEE elastomer materials hasincreasingly attracted the attention of researchers at home andabroad. At present, the United States has a position in the R& D and production of TPEE elastomer materials in theworld. It can be said that it is the main producer and consumer ofTPEE materials in the world. TPEE thermoplastic elastomer hasexcellent thermal stability, plastic under normal operatingconditions and will not produce toxic gas, Without plasticizers andalmost no additives, problems such as viscosity changes are reducedto a certain extent. Tpc-et elastomers are hygroscopic (like allpolyesters), and will absorb moisture in the air if exposed. Thetemperature is much higher than the melting point. Excessive water(all moisture is greater than 0.1%) causes the hydrolyticdegradation of the polymer. This degradation will not show asvisual defects, but lead to poor physical properties, brittlenessand poor performance. Especially at low temperature, low-density orhigh-density polyethylene resin can be used to clean TPEEelastomer.
