Characteristics of engineering plastics

Engineering plastics can be valued because of its rich raw material resources, superior functions and low cost. What is more important is that it has many properties that can not be compared with metals and other materials.

1. low density, light weight and high specific strength. The relative density of engineering plastics is about 1.0-2.0, which is 1/8 of steel and 1/2 of aluminum Its specific tensile strength (tensile strength / density) can be as high as 1700-4000 (glass fiber reinforced engineering plastics), while that of steel is 1600 and that of aluminum is only 400.

2. good chemical stability. Engineering plastics have excellent stability to general acids, alkalis and solvents, superior to metal materials.

3. excellent electrical insulation function.

4. excellent wear resistance, friction reduction and self-lubricating functions.

5. excellent shock absorption, impact resistance, noise elimination and function.

6. compared with metal materials, it is easy to process and form and has high production efficiency.

But engineering plastics also have its shortcomings. For example, the mechanical strength, hardness and thermal conductivity are not as good as metal; High temperature resistance is inferior to ceramics; And it has the characteristics of large water absorption, easy photochemical and creep. Therefore, engineering plastics, metals, ceramics, glass and other materials can complement each other in application and give full play to their respective characteristics and interests. (end)
