Most plastics are light, chemically stable and do not rust;
good impact resistance;
It has good transparency and abrasion resistance.
Good insulation, low thermal conductivity;
General formability, good coloring, low cost of processing;
Most plastics have poor heat resistance, high thermal expansion rate and easy to burn;
Poor dimensional stability, easy to deform;
Most plastic low temperature resistance, brittle at low temperature, easy to aging;
Some plastics are easily soluble in solvents. Plastics can be differentiated into thermosetting and thermoplastic type II, the former can not be re-molded use, the latter may be repeated production. Thermal plasticity has a large physical elongation, generally in 50%~500%.
At different elongation rates The June does not completely change linearly. The different properties of plastics determine their use in the industry, and with the progress of technology, the modification of plastics has not stopped research. It is hoped that in the near future, plastics can be used more widely after modification, and can even replace materials such as steel and no longer pollute the environment.
