1 Most plastics are light, chemically stable and will not rust;
2 Good impact resistance;
3 Has good transparency and wear resistance;
4 Good insulation, low thermal conductivity;
5 Generally, the moldability and colorability are good, and the processing cost is low;
6 Most plastics have poor heat resistance, large thermal expansion rate and easy burning;
7 Dimensional stability is poor, easy to deform;
8 Most plastics have poor low temperature resistance and become brittle at low temperatures;
9 Easy to age; 10 some plastics are easily soluble in solvents.
Plastics can be distinguished as thermoset and thermoplastic. The former cannot be reshaped and the latter can be re-produced.
