PS plastic raw materials properties and applications Introduction
Polystyrene (PS) type of plastic is a relatively old plastic, production technology has also been more complete. Compared with other plastics, PS is characterized by good transparency (light transmission rate of 88% -92%) and surface gloss, easily dyed, high hardness, good rigidity, in addition to good water resistance, chemical resistance and processing flow properties. Its main drawback is: brittle, low-impact strength, easy to a stress cracking, and poor heat resistance.
Often sold on the market two HIPS and GPPS, HIPS which is modified with high impact resistance of polystyrene, which has good impact resistance. GPPS (or GPS) for the ordinary polystyrene.
PS is mainly used in:
Electronics: can be used to manufacture television sets, tape recorders and a variety of electrical instruments, parts, shell, high-frequency capacitors;
architecture: transparency for public building components, optical devices and transparent model of production such as shade, instrument housings, packaging containers.
Daily: combs, boxes, toothbrush, pen rod, school supplies, children's toys;
other areas: can be used for foam production shockproof, sound insulation, thermal insulation, sandwich construction materials, refrigerators, trains, ships, aircraft, also used them as heat, noise, etc. can also be used to make life buoy.
