TPU's soft section can use a variety of polyols, which can be roughly divided into two types of polyether and polyester systems. 　　Polyether (Ether): high strength, hydrolysis resistance and high resilience, good low temperature performance.

Generally, when designing a plastic mold, after determining the mold structure, the detailed design of each part of the mold can be carried out, i.e., determining the dimensions of each template and part, cavity and core dimensions, etc. This will involve the main design parameters such as material shrinkage. This will involve the main design parameters such as the shrinkage of the material. Therefore, the dimensions of each part of the cavity can only be determined if the shrinkage rate of the molded plastic is specifically known. Even if the selected mold structure is correct, but the parameters used are not appropriate, it will not be possible to produce quality plastic parts.

　　TPE,TPR covered ABS products have met a lot of people's needs in life, it provides a lot of convenience and comfort for people's lives, it has a great impact on people's lives. In life, we often see the figure of wrapped products, such as sports equipment, electronic appliances, and luggage accessories and so on.

Due to the diversity of TPE types, and the complexity of some TPE species blending system determines the uncertainty of TPE density, the specific gravity of the main TPE, briefly listed below.

TPE (Thermoplastic TPE (Thermoplastic Elastomer) is a thermoplastic elastomer material, with high strength, high resilience, injection molding processable characteristics, a wide range of applications, environmental protection, non-toxic safety, excellent coloring TPE usually refers to the SEBS, SBS base material blend of modified elastomers. This kind of TPE general shrinkage rate is large, so how much is it? The following will follow the plastic Bo plastic uncle together to understand.

TPE, TPV and TPU belong to the same category, collectively known internationally as thermoplastic elastomer, abbreviation: TPE

SEBS is a linear triblock copolymer with polystyrene as the terminal segment and ethylene-butene copolymer obtained by hydrogenation of polybutadiene as the intermediate elastic block.SEBS does not contain unsaturated and double bonds, so it has good stability and aging resistance.
