Polycarbonate (PC) is also known as PC plastic. It is a high molecular polymer containing carbonate group in the molecular chain (aromatic polycarbonate has been industrialized). Due to the particularity of polycarbonate structure, it has become the fastest growing general engineering plastic among the five engineering plastics.It is a strong and tough thermoplastic resin with excellent comprehensive mechanical, thermal and electrical properties. The impact strength reaches 44kj /m2 and the tensile strength is >60MPa.It has good heat resistance and can be used for a long time at -60~120ºC.Its melt viscosity is much higher than that of general thermoplastic. Polycarbonate has excellent electrical properties. Its volume resistivity and dielectric constant are equivalent to those of polyester film, which are 5×1013Ω·m and 2.9 (106 Hz). It also with good light transmittance, the light transmittance is 85% ~ 90%.Its water absorption is low, only 0.16%.Excellent weather resistance;Good colorability;The flame resistance complies with the standards of 94 VL and 94 V-2 of UL specifications. It is a self extinguishing resin. Polycarbonate has excellent oil resistance. After soaking in natural gas for 3 months or in lubricating oil at 125 ºC for 3 months, the product size and quality basically remain unchanged. Polycarbonate mainly used in the field of high transparency and high impact strength. For example: As an optical material, optical disc material is one of the main uses of polycarbonate.Used as the shell of electrical tools, such as the shell of electric hand drill. In terms of safety and medical treatment, it can be used as safety helmet, aerospace helmet, explosion-proof glass, protective glasses and medical surgical utensils that can be disinfected at high temperature. In aviation, transportation and optical machinery, it can be used as windshield glass, seat window cover, lampshade, sunglass glass, optical disc, optical and mechanical parts of camera, etc. In construction and agriculture, it is widely used as window glass and glass greenhouse with high impact strength, which has high safety and decoration.In the textile industry, it can make all kinds of weft tubes, yarn tubes, wooltubes, hemp tubes, etc. Packing:25kg/ bag,
