Description
Product Description
General Purpose Polystyrene：
GPPS is a thermoplastic resin, colorless,odorless, tasteless and lustrous, transparent bead-like or granular solid.
It has a density of 1.04~1.09, a transparency of 88%~92%, and a refractive index of 1.59~1.60. Under stress, it produces birefringence, which is known as the stress-optical effect. The melting temperature of the product is 150～180℃, the thermal decomposition temperature is 300℃, the thermal deformation
temperature is 70～100℃, and the long-term use temperature is 60～80℃. In the lower heat deflection temperature 5 ~ 6 ℃, after annealing treatment, the stress can be eliminated, so that the heat deflection temperature is increased.

Our Advantages
Features of GPPS particles:
GPPS has good rigidity, light transmittance, corrosion resistance, electrical insulation property and dyeability.
It features low shrinkage rate, good molding and processing properties and short molding cycle time. In addition, it allows high-speed injection molding and products made from it have excellent dimensional stability.
Application
GPPS can be used to make daily necessities,electrical instrument shells, toys, lamps, cosmetic containers, decorations, optical parts (such as triangular prisms and lens),auto headlights, telecom accessories, capacitor films, highfrequency insulating materials, waveguide tubes, chemical vessels,structural foam products, etc.
Package, Storage and Transportation：
1.The resin is packaged in internally film-coated polypropylene woven bags. The net weight is 25Kg/bag.
2.The resin should be stored in well-ventilated and dry warehouses and away from fire and direct sunlight. It should not be piled up in the open air.
3.During transportation, the material should not be exposed to strong sunlight or rain and should not be transported together with sand, soil, metal, coal or other contaminants.
4.Transportation together with corrosive or flammable substance is strictly prohibited.
