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
HIPS
HIPS are widely used in many appliances and industries because of their ease of manufacture and low cost. Major industries and markets include packaging, disposables, appliances and consumer appliances, toys and entertainment, construction products and decorations.

HIPS has good fluidity, high rigidity, good heat resistance, superior molding performance and easy coloring. Application
Application:
HIPS can be used to make shells of electrical household appliances, refrigerator lining, plates, TV sets, recorders, telephone body cases, stationary, toys, packaging vessels,daily necessities, dishware, etc.
Package, Storage and Transportation:
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. 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.Transportation together with corrosive or flammable substance is strictly prohibited.
