General Purpose Polystyrene GPPS resin
General Purpose Polystyrene is a kind of thermoplastic resin, is a colorless, odorless, tasteless, shiny, transparent beaded or granular solid. Density is 1.04 to 1.09, transparency is 88% to 92%, refractive index is 1.59 to 1.60. In the stress function, resulting in birefringence, the so-called stress - optical effect. Product of the melting temperature is 150 to 180 ° C, thermal decomposition temperature is 300 ° C, the heat distortion temperature is 70 to 100 ° C, long-term use temperature is 60 ~ 80 ° C
Physical properties
GPPS is colourless, odourless, tasteless and shiny, transparent particles. Qualitative light, cheap, low water absorption, good color, good dimensional stability, electrical products, transparent, easy processing.
Application:
1, GPPS can be used for daily necessities, electrical, instrument shell, toys, lamps, household appliances, stationery, cosmetics containers, indoor
2, also can be used in outdoor decoration, fruit tray, optical components, such as prism, lens) lens window glass and molding, headlights, telecom accessories, electric frequency capacitor films,
Storage
It should avoid damp, contaminated and direct sun light during transport. And should be stored in ventilated and dry place. Do not put it with flammable and corrosive substances together, and away from the fire
