[GPPS ](General Purpose Polystyrene GPPS Granules)
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.
[Using]Because polystyrene is transparent and has excellent rigidity, electrical properties and printing properties, especially good hygiene and low price, it has broad application prospects in food packaging. In the electromechanical industry, instrumentation, communication equipment industry has been widely used in a variety of instrument shell, lampshade, optical parts, instrument parts, transparent window mirror, transparent model, chemical acid storage tank, acid conveyor tank, telecommunications parts, high frequency capacitors, high frequency insulation liner, bracket, insert and frozen insulation materials. Also widely used in a variety of daily necessities, such as bottle caps, containers, decorations, buttons, combs, toothbrushes, soap boxes, cigarette boxes and toys.
[Molding processing] Polystyrene has good fluidity, good processing performance, easy coloring and good dimensional stability. It can be processed into various parts by injection molding, extrusion, blow molding, foaming, thermoforming, bonding, coating, welding, machining, printing and other methods, especially suitable for injection molding.
[Features]
Good heat distortion resistance grades with intermediate strength and flow.
High toughness & good melt strength
Comply with FDA 21 CFR 177.1640 and other European regulations for food contact applications.

1.General purpose polystyrene (GPPS)
GPPS, can be used for daily necessities, electrical appliances, instrument housings, toys, lamps, household appliances, stationery, cosmetics containers, indoor and outdoor decorations, fruit plate, optical parts (such as prism, lens) lens and molding, Lamps, telecommunications accessories, electric frequency capacitors film, high-frequency insulation materials, television sets and other containers, waveguide, chemical containers.ade is mainly used for making rotomolded products, large-sized outdoor toys, storage tanks, roadblocks, etc.
2. Expandable polystyrene (EPS)
EPS has also been used for a large number of decorative materials, film and television scene layout, character modeling, marine life jackets and buoys. In particular, large foam sheet market demand is very large, as color steel sandwich panel, steel (board) grid composite light panels, wall outside the paste board, roof insulation boards and geothermal panels, it is more widely Used in the field of housing construction, for insulation, heat insulation, waterproof and moisture-proof materials on the ground.
