1. Light weight

Plastics are light materials with relative densities ranging from 0.90 to 2.2.

2. Excellent chemical stability

Most plastics are well resistant to chemicals such as acids and alkalis.

3. Excellent electrical insulation performance

Ordinary plastics are electrical bad conductor, its surface resistance, volume resistance is very large, breakdown voltage is large, medium loss Angle tangent value is very small.

4. A poor conductor of heat, with noise and shock absorption

Generally speaking, the thermal conductivity of plastic is relatively low, the micropores of foam plastic contain gas, its heat insulation, sound insulation, shock resistance is better.

5. Wide distribution of mechanical strength and high specific strength

Some plastics are as hard as stone and steel, and some are as soft as paper and leather. From the hardness, tensile strength, elongation and impact strength of plastic mechanical properties, a wide range of distribution, there is a lot of choice.

Nowadays, plastic processing is more and more widely used, and the scope is more and more large. In industry, people use its electrical insulation is good, widely used in motor, electrical appliances, instrumentation and telecommunications equipment manufacturing. Such as all kinds of wire, cable, machine casing, semiconductor radio casing, etc., are made of plastic. In the construction, machine manufacturing, shipbuilding, automobile industry, plastic has been used as ceiling, floor, decorative board, sound insulation board, ceramic tile, all kinds of gears, bearings, CAM and other machine parts, steering wheel on the car, lamp shade and a variety of structural materials. Plastic Parts can be used in many places.
