Overview
PS injection molding grade 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
PS injection molding grade can be used to make shells of cassette boxes, videotape boxes and disk boxes , TV sets and recorders, liners of refrigerators, parts of washing machines, lamp shades, food plates, cups, instrument shells, optical instrument surface, parts of electrical appliances, foaming products, etc.
Package, Storage & Transportation
The resin is packaged in internally film-coated polypropylene woven bags. The net weight is 25Kg/bag. 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.
