Application of plastic ball in industry
2021-01-06Hollow plastic ball has the advantages of durability, corrosion resistance and elasticity. Precision hollow balls are made of high density polyethylene, polypropylene, polytetrafluoroethylene (PTFE) or heat-resistant polyvinylidene fluoride (PVDF). Made of high density and low density polypropylene (HDPE and LDPE) for outdoor use. Polypropylene (PP) hollow plastic balls have corrosion resistance. PVDF or PTFE plastic balls are recommended for high temperature applications. Used in industry, manufacturing and cosmetics industry, hollow
Solution of plastic ball in industrial seal valve production
2021-01-05Now in today's automation industry, the plastic ball is often widely used in the production of industrial seal valve. In the product design, such as electronics, electrical appliances, valves, sanitary ware, faucets and other products, the plastic ball plays the role of sealing and leak proof. The plastic ball is a product with a little hardness. When it is matched with another product, the material of the other product is better, which is metal, rubber and silica gel. Either the hardness is higher or lower than the plastic ball, only in this way can the plastic ball play a better role
Classification of main materials of plastic balls and common terms for plastic balls
2021-01-05Plastic balls can be roughly divided into two types: "thermosetting plastic balls" and "thermoplastic plastic balls". According to heat resistance, thermoplastic balls are divided into three categories: general plastic balls, general engineering plastic balls and super engineering plastic balls. In addition, according to the distribution degree of polymer chain, it can be divided into "crystalline plastic ball" and "non crystalline plastic ball". Thermosetting resin plastic ball is softened by heating and cured by chemical reaction in the molding process. Even if heated later
