Compared with other materials, Plastic Balls Manufacturer shares the following performance characteristics:
1. Light weight
Plastic is a lighter material with a relative density distribution between 0.90-2.2. Obviously, can the plastic float on the water? Especially foamed plastics, because of the micropores inside, the texture is lighter, and the relative density is only 0.01. This feature makes plastics useful in the production of products that require reduced weight.
2. Excellent chemical stability
Most plastics have good corrosion resistance to chemicals such as acids and alkalis. Especially the polytetrafluoroethylene (F4) commonly known as the plastic king, its chemical stability is even better than gold, and it will not deteriorate after being cooked in "aqua regia" for more than ten hours. Because F4 has excellent chemical stability, it is an ideal corrosion-resistant material. For example, F4 can be used as a material to transport corrosive and viscous liquid pipelines.
3. Excellent electrical insulation properties
Ordinary plastics are poor conductors of electricity, and their surface resistance and volume resistance are very large, which can be expressed by numbers up to 109-1018 ohms. The breakdown voltage is large, and the dielectric loss tangent is small. Therefore, plastics are widely used in the electronics industry and machinery industry. Such as plastic insulated control cables.
4. Poor thermal conductor, with noise reduction and shock absorption
Generally speaking, the thermal conductivity of plastic is relatively low, which is equivalent to 1/75-1/225 of steel, and the micropores of foam plastic.
It contains gas, which has better heat insulation, sound insulation and shock resistance. For example, the thermal conductivity of polyvinyl chloride (PVC) is only 1/357 of steel and 1/1250 of aluminum. In terms of thermal insulation capacity, single glass plastic windows are 40% higher than single glass aluminum windows and 50% higher than double glass. After combining the plastic form with the hollow glass, it can be used in residences, office buildings, wards, and hotels. The benefits of saving heating in winter and air conditioning in summer are obvious.
5. Wide distribution of mechanical strength and high specific strength
Some plastics are as hard as stone and steel, and some are soft as paper and leather. From the mechanical properties of plastics such as hardness, tensile strength, elongation and impact strength, they have a wide distribution range and have a lot of choices. Because plastic has a small specific gravity and high strength, it has a high specific strength. Compared with other materials, plastics also have obvious shortcomings, such as easy to burn, less rigidity than metal, poor aging resistance, and heat resistance.
