Product Description
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
Application
1.Food packaging.
2.Electrical industrial, instrumentation, communications equipment industry and other various instruments has been widely used as a shell, lamp, optical parts, equipment parts, transparent windows mirror, transparent model, acid, chemical storage tank, acid tank transport, telecommunications components, high frequency capacitors, high frequency insulation pads, brackets, inserts and frozen insulating materials.
3.All kinds of daily necessities,such as Plastic Cutlery, Toys.
Note:As the various of types,if you have any requirement,please tell me your reqirement about the product,the MFI and your specific application,then we could supply you the right product and best price,also we could produce follow your demand.
Storage
