русский1. Low density: Plastics have low density, which is of great significance for reducing the weight of mechanical equipment and saving energy, especially for vehicles, ships, aircraft, and spacecraft.
2. High specific strength and specific stiffness: The absolute strength of plastic is not as high as that of metal, but the density of plastic is small, so the specific strength (σb/ρ) and specific stiffness (E/ρ) are quite high. In particular, reinforced plastics made of various high-strength fibrous, flake and powdered metals or non-metals as fillers have higher specific strength and specific stiffness than metals.

4. Good electrical insulation, heat insulation and sound insulation performance.
5. Good wear resistance and self-lubrication: Plastic has small friction coefficient, good wear resistance, and good self-lubrication, plus high specific strength and low transmission noise. It can be used in liquid media, semi-dry or even dry friction work effectively under the conditions. It can be made into machine parts such as bearings, gears, cams and pulleys, and is very suitable for occasions where the speed is not high and the load is not large.
6. Strong bonding ability.
7. Good forming and coloring properties.
