Information

PVC can be seen everywhere in people's daily life. The natural color of PVC is yellowish, translucent and shiny. The transparency is better than that of polyethylene and polypropylene and worse than that of polystyrene. Depending on the amount of additives, it can be divided into soft and hard polyvinyl chloride. Soft products are soft and tough and feel sticky. The hardness of hard products is higher than that of low-density polyethylene and lower than that of polypropylene. There will be whitening at the bend. PVC plate is mainly used in building materials, packaging, medicine and many other industries. Among them, the building materials industry accounts for a large proportion, accounting for 60%, followed by the packaging industry, and several other small-scale application industries. PVC can not only express the colors of nature, but also the colors in people's imagination.

PVC hollow board is not only widely used in China, but also in Germany, 40% of furniture uses PVC as surface materials, such as desk, bookshelf, sofa, kitchen cabinet, etc. It is a popular and widely used synthetic material in the world. Its global usage is the highest among all kinds of synthetic materials. According to statistics, in 1995 alone, the production of PVC in Europe was about 5 million tons, while its consumption was 5.3 million tons. In Germany, the average production and consumption of PVC is 1.4 million tons. PVC is being produced and applied all over the world at a growth rate of 4%. The growth in Southeast Asia is particularly significant. Why are PVC sheets so popular? The following introduces the performance characteristics of PVC plate to understand PVC plate.

1. General performance. PVC resin is a white or light yellow powder with a relative density of 1.35-1.45. The hardness and softness of the product can be adjusted by the number of plasticizers added. Pure PVC has low water absorption and air permeability.
2. Mechanical properties. PVC has high hardness and mechanical properties. It increases with the increase of molecular weight, but decreases with the increase of temperature. Rigid PVC has good mechanical properties, and its elastic modulus can reach 1500-3000mpa. The elasticity of soft PVC is 1.5-15 MPa. But the elongation at break is as high as 200% - 450%. The friction of PVC is general, with static friction coefficient of 0.4-0.5 and dynamic friction coefficient of 0.23.
3. Thermal performance. The thermal stability of PVC is very poor. It begins to decompose at 140 ℃ and the melting temperature is 160 ℃. PVC has small coefficient of linear expansion, flame retardancy and oxidation index of more than 45.
4. Electrical performance. PVC is a polymer with good electrical properties, but its electrical insulation is not as good as PP and PE due to its large polarity. Dielectric constant, dielectric loss tangent and volume resistivity are large, and corona resistance is poor. It is generally suitable for medium and low voltage and low frequency insulating materials.
5. Environmental performance. PVC is resistant to most inorganic acids, alkalis, salts and most organic solvents. Suitable for medicine, chemical industry, anti-corrosion materials, etc.
