Characteristics of plastic:
Most plastics are light, chemically stable, and will not rust;
Good impact resistance;
Has good transparency and wear resistance;
Good insulation and low thermal conductivity;
Generally, the moldability and coloring are good, and the processing cost is low;
Most plastics have poor heat resistance, high thermal expansion rate, and are easy to burn;
Poor dimensional stability and easy to deform;
Most plastics have poor low temperature resistance, become brittle at low temperatures, and are easy to age;
Certain plastics are easily soluble in solvents.
