Most of the plastic light, chemical stability, will not rust;
good impact resistance;
With good transparency and wear resistance;
Good insulation, low thermal conductivity;
General molding, coloring good, low processing costs;
Most plastic heat resistance is poor, the thermal expansion rate is big, easy to burn;
Poor dimensional stability, easy deformation;
Most plastics are poor at low temperature, brittle at low temperature and easy to be aged. Some plastics are easily soluble in solvents.
