Plastic Nature

May 23, 2019

1. Most plastics are light, chemically stable, and will not rust; 2. good impact resistance; 3. good transparency and wear resistance; 4. good insulation, low thermal conductivity; 5. general formability, colorability Good, low processing cost; 6. most plastics have poor heat resistance, large thermal expansion rate, easy to burn; 7. dimensional stability is poor, easy to deform; 8. most plastics have poor low temperature resistance, become brittle at low temperature; 9. easy to age; 10. some plastics are easy Soluble in solvent.

Plastics can be distinguished into two types, thermosetting and thermoplastic. The former cannot be reshaped and the latter can be repeatedly produced.
