(Summary description)1. low density: the density of plastic is small, 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 stiffness: the good strength of plastic is not as high as that of metal, but the density of plastic is small, so the specific strength（ σ b/ ρ)、 Specific stiffness (e/ ρ) Quite high. In particular, reinforced plastics made of various high-strength fibrous, flaky and powdered metal or non-metal fillers have higher specific strength and stiffness than metals.
3. good chemical stability: most plastics have good resistance to acid, alkali, salt, water and gas. Under normal conditions, they do not react with these substances.
4. good electrical insulation, heat insulation and sound insulation performance.
5. good wear resistance and self lubrication: the plastic has small friction coefficient, good wear resistance, good self lubrication, high specific strength and low transmission noise. It can work effectively in liquid medium, semi dry or even dry friction conditions. It can be made into machine parts such as bearings, gears, cams and pulleys. It is very suitable for occasions with low speed and low load.
6. strong bonding ability.
7. good forming and coloring performance.
