1. Engineering plastics are light in weight and low in relative density
The relative density of engineering plastics is generally between 1.0 and 2.0, which is much lower than that of metals. It is light in weight and can replace some traditional metal materials for use in aerospace vehicles, vehicles and other fields.
2. High specific strength of engineering plastics
Reinforcement with glass fiber, carbon fiber and other fibers can greatly improve the tensile strength. The ratio of tensile strength to relative density is generally 1500-1700, or even as high as 4000 (steel 1600, aluminum 1500).
Tensile strength: refers to the stress at which a material produces maximum uniform plastic deformation. In the tensile test, the tensile strength is the maximum tensile stress that the sample receives until it breaks, and the result is expressed in MPa.
3. Outstanding wear resistance and self-lubricating properties
Use engineering plastic for sale as friction parts. Compared with wear-resistant metal alloys, the wear rate is less than 1:5, and fluorine plastics are better.
4. Excellent mechanical properties of engineering plastics
In a wide temperature range, many engineering plastics, especially reinforced engineering plastics, have excellent impact resistance and fatigue resistance.
5. Excellent electrical insulation of engineering plastics
Almost all engineering plastics have excellent electrical insulation and arc resistance properties, and can be among the ranks of excellent insulating materials.
6. Chemical stability of engineering plastics
It has good corrosion resistance to acids, alkalis and general organic solvents.
7. Engineering plastics have better dimensional stability of parts
8. Engineering plastics have high heat resistance
When general engineering plastics are reinforced with different glass fibers, the long-term continuous use temperature of UL exceeds 100 ℃, and the index of special engineering plastics generally exceeds 150 ℃.
9. Engineering plastics have excellent shock absorption, noise reduction and burial performance for foreign bodies
When engineering plastics are used as moving parts, there is no metal impact noise and excellent shock absorption and noise reduction performance. For the presence of abrasive particles, foreign objects can be buried, unlike metal that may be bitten or scratched before.
10. Good processing performance of engineering plastics
Engineering plastics can be processed at lower temperatures (usually below 400°C) by injection molding, extrusion, blow molding, etc. The products can be reprocessed by mechanical methods, the dimensions are stable, the interchangeability of the finished products is strong, and the mold cost is low. Compared with processing metal, it can save about 50% of energy consumption, shorten the working hours and improve the yield.
