Plastik Granule Virgin Ps Plastic Granules GPPS 525

Product Description Cheap Price Plastik Granule Virgin Ps Plastic Granules Lanhua GPPS 525 High transparent, heat-resistant and impact resistant household electrical materials GPPS-525 polystyrene (PS) refers to the polymer synthesized by free radical addition polymerization of styrene monomer. It is a colorless and transparent thermoplastic with a glass transition temperature higher than 100. Therefore, it is often used to make various containers that need to withstand the temperature of boiling water, as well as foam lunch boxes. The glass transition temperature of polystyrene is 80 ～ 105, the amorphous density is 1.04 ～ 1.06g/cm3, the crystal density is 1.11 ～ 1.12g/cm3, the melting temperature is 240, and the resistivity is 1020 ～ 1022 Ω · cm. Thermal conductivity: 0.116 W/(m · K) at 30h. Generally, polystyrene is amorphous random polymer, which has excellent thermal insulation, insulation and transparency. The long-…
