What are the advantages of PVC sheet products compared with other materials? The specific properties are as follows:
1.Lighter weight
Plastic products are relatively light materials, with a relative density distribution ranging from 0.90-2.2. Apparently, plastic can float around wherever it wants. Especially expanded polystyrene, due to its small pores, is light in texture and has a relative density of only 0.01. Such characteristics make plastic products suitable for the production of products that require weight reduction.
2.Good chemical stability
Most plastic products have good corrosion resistance to chemicals such as acids and alkalis. Especially polytetrafluoroethylene (F4), its chemical reliability even exceeds that of gold and silver, and it will not deteriorate when placed in hot water for more than 10 hours.
3.Good antistatic properties
Generally, PVC sheet products are basically conductors with poor electrical properties, and their surface resistivity and volume resistance are large, which can reach 109a 1018 ohms in one number. The breakdown voltage is large and the dielectric loss tangent value is small. Therefore, plastic products are widely used in the electronics industry and machinery industry. Such as plastic insulated control cables.
4.A poor conductor of heat, with sound absorption and shock absorption functions
Generally speaking, the thermal conductivity of PVC sheet products is relatively low, equivalent to 1/75-1/225 of steel and the pores of foam plastic. With gas, its temperature insulation, sound insulation, noise reduction and earthquake resistance are better.
5.Mechanical strength has a wide distribution range and high specific strength
Some PVC sheet products such as stone and steel, and some soft products such as printing paper and leather products; from the perspective of physical properties such as hardness, tensile strength, elongation and impact strength of plastic products, the distribution range is wide, and there are many Large application selection space. Plastic products have small specific gravity, high strength and high specific strength.
