Properties of plastics are:
1, most plastics are lightweight, chemically stable, will not rust;
2, good impact resistance;
3, with good transparency and abrasion resistance;
4, good insulation, low thermal conductivity;
5, general molding, good coloring, low processing costs;
6, most of the plastic heat resistance is poor, thermal expansion, easy to burn;
7, poor dimensional stability, easy to deform.
Expanded Information:
1, industry: plastics are widely used in the electrical and electronics industry, the manufacture of insulating materials and packaging materials;?
2, the mechanical industry with plastic to make gears. Shaft tile and many parts instead of metal;
3, chemical industry with plastic containers and other anticorrosive materials;
4, used in the construction industry as doors, windows, staircase handrails, floor tiles, ceilings, insulation boards, downpipes, decorative panels and sanitary ware, etc..
5, the defense industry: plastic is an important material for conventional weapons, aircraft, ships, rockets, missiles, artificial satellites and other areas.
