1. Good insulation and low thermal conductivity.

2. Excellent colorability and low processing cost.

3. Light weight, relatively stable and not easy to corrode.

4. The low temperature resistance is relatively poor, and it is easy to become brittle in the low temperature state.

5. It has good transparency and abrasion resistance.

6. Some plastics are easily soluble in solvents.

7. Slightly lower stability, easier to deform and aging.

     Plastics can be divided into two types: thermoplastic and thermosetting. Thermoplastics can be reproduced, while thermosetting plastics cannot be reused.
