1, good insulation, low thermal conductivity.

2, excellent coloring, low processing cost.

3, light weight, relatively stable, not easy to corrosion.

4, low temperature resistance is poor, easy to become brittle at low temperature.

5, with good transparency and wear resistance.

Some plastics are easily soluble in solvents.

7, slightly lower stability, easy deformation, easy aging.

Plastics can be divided into thermoplastic and thermosetting properties. Thermoplasticity can be repeated, whereas thermosetting plastics cannot be reused.
