Plastic is a synthetic or natural polymer compound that can be arbitrarily pinched into a variety of shapes to keep the shape of a material or a plastic product at last.
Charateristics of palstic are as follows:
1.Most plastics are light, chemically stable, and will not rust.
2.Good impact resistance;
3.It has good transparency and wear resistance.
4.Good insulation, low thermal conductivity;
5.General molding, good coloring, low processing cost;
6.Most of the plastics are poor in heat resistance, high in thermal expansion and easy to burn.
7.The dimensional stability is poor and easy to deform.
8.Most plastics are low temperature resistant, brittle at low temperature and easy to aging.
