Five Reasons To Choose Plastic For Tarpaulin Production

The reason why the tarpaulin chooses the material of plastic, according to the analysis of relevant persons, there are five main reasons, namely:

1. Excellent electrical insulation performance: Ordinary plastics are poor conductors of electricity, and their surface resistance and volume resistance are very large, which can reach 109 to 1018 ohms in digital representation. The breakdown voltage is large, and the dielectric loss tangent value is small. Therefore, plastics have a wide range of applications in the electronics and machinery industries. Such as plastic insulated control cables.

2. Light weight: Plastic is a lighter material, and its relative density is between 0.90 and 2.2. Obviously, can plastic float to the surface? In particular, foamed plastics are lighter in texture and have a relative density of only 0.01 due to the micropores in them. This property allows plastics to be used in the production of products that require reduced weight.

3. Poor heat conductors have the functions of noise reduction and shock absorption: Generally speaking, the thermal conductivity of plastics is relatively low, which is equivalent to 1/75-1/225 of steel, and the micropores of foam plastics. It contains gas, and its heat insulation, sound insulation and shock resistance are better. 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, single glass plastic windows are 40% higher than single glass aluminum windows, and double glass windows are 50% higher.

4. Excellent chemical stability: the vast majority of plastics have good corrosion resistance to acids, alkalis and other chemical substances.

5. Wide distribution of mechanical strength and high specific strength: some plastics are hard such as stone and steel, and some are soft such as paper and leather; from the mechanical properties of plastics such as hardness, tensile strength, elongation and impact strength, Wide distribution, there is a lot of room for choice. Due to the small specific gravity and high strength of plastic, it has a high specific strength.
