1.the most plastic light weight, chemical stability, will not rust;
2.good impact resistance;
3.has good abrasion resistance and transparency;
4.insulation, low thermal conductivity;
5.general shape, good coloring, low processing costs;
6.most plastic heat-resistant low thermal expansion rate, flammable;
7.Sadly, poor dimension stability, easy deformation;
8.most plastic low temperature tolerance of difference, become brittle at low temperatures;
9.Krispy Kreme is easy to get older;
10.some plastic is easy to dissolve in a solvent.
