What are the advantages and disadvantages of plastics? 3 advantages, 2 disadvantages

1, most plastics are light, chemically stable and will not rust;

2. Good impact resistance;

3. Good transparency and wear resistance;

4. Good insulation and low thermal conductivity;

5, good overall formability and coloring, and low processing cost;

Disadvantages:

1, most plastics have poor heat resistance, large thermal expansion rate and are easy to burn;

2. Poor dimensional stability and easy deformation;

3. Most plastics have poor low temperature resistance and become brittle at low temperature;

4, easy to age;

5. Some plastics are soluble in solvents.
