Five reasons for choosing plastic as a material for tarpaulin production

Plastic tarpaulin manufacturers choose plastic as the material for making tarpaulin. According to the analysis of relevant people, there are five main reasons, namely：

1. 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 in numbers as high as 109 to 1018 ohms.The breakdown voltage is large, and the tangent of the dielectric loss angle is small.Therefore, plastics are widely used in the electronics industry and machinery industry.Such as plastic insulated control cables.

2. Light weight: Plastic is a lighter material, with a relative density distribution between 0.90-2.2.Obviously, can plastic float on the water?Especially foamed plastics, because of the micropores inside, have a lighter texture and a relative density of only 0.01.This characteristic allows plastics to be used in the production of products that require weight reduction.

Third, the poor conductor of heat has the effect of silencing 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.It contains gas, which has better heat insulation, sound insulation and shockproof properties.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 windows.

4. Excellent chemical stability: Most plastics have good corrosion resistance to acid, alkali and other chemicals.

5. Wide distribution of mechanical strength and high specific strength: some plastics are as hard as stone and steel, while others are as soft as paper and leather; judging from the mechanical properties of plastics such as hardness, tensile strength, elongation and impact strength, the distribution range is wide, and there is a lot of choice for use.Because of the small specific gravity and high strength of plastics, they have a high specific strength.
