With the development of technology, the number of decoration materials is now increasing. For example, PVC sheet is a new type of decorative material, which is lightweight, waterproof and moisture-proof, and is widely used in tooling and furniture. Therefore, many people want to understand the price of PVC before buying PVC plates, so they buy cost-effective PVC plates. So, let's find out what the price of PVC sheet is.

What is PVC sheet sheet

In fact, it is plastic sheet, the raw material used in the production is PVC, and the finished color is generally white and gray. Of course, many manufacturers can now also produce colored PVC panels. We can choose the right color according to our needs. Since the cross-section of the PVC board is a honeycomb-like mesh structure, the stability is good. PVC sheet is an excellent thermoforming material, which can replace some stainless steel and other corrosion-resistant synthetic materials, and is widely used in chemical, petroleum, electroplating, water purification and treatment equipment, environmental protection equipment, mining, medicine, electronics, communication and decoration industries.

What is the price of PVC sheet sheet

Usually, the market price of such materials is about 20-35 yuan / kg, but due to the difference in the quality of different brands and grades of plates, the market price also varies greatly. For example, PP sheets with the same thickness of 1 cm are about 9.5 yuan/km per square meter, but PVC sheets are about 20k per square meter. The density of PVC sheet is about 1.45-1.75, the lighter its density, the better the weight, and the higher the price.

Is PVC sheet good

One of the biggest advantages of this material is light weight, easy construction, good waterproof and moisture-proof, good scratch resistance, and high durability. When the PVC board is damaged, it is easy to replace. We only need to unload the things on the side first, then take the boards out of the hydraulic press one by one, replace the broken boards with new ones, and then reinstall the hydraulic press. PVC sheet has a long life, and is economical, has a wide range of use, and is used in large quantities. However, PVC sheet has the disadvantage of poor high temperature resistance and easy deformation in a high temperature environment.

The general performance of PVC resin is white or light yellow powder, the relative density is 1.35-1.45. The softness of the product can be adjusted by adding plasticizers.

Mechanical properties: PVC sheet has high hardness and mechanical properties. It rises as the molecular weight increases, but decreases as the temperature increases. Hard PVC has good mechanical properties, and its elastic modulus can reach 1500-3000MPa. Soft PVC has an elasticity of 1.5-15 MPa. However, the elongation at break reaches 200%-450%. The friction of PVC is general, the static friction coefficient is 0.4-0.5, and the dynamic friction coefficient is 0.23.

Thermal propertiesThe thermal stability of PVC is very poor, decomposition begins at 140, and the melting temperature is 160. PVC sheet has a small linear expansion coefficient, is flame retardant, and the oxidation index is as high as 45 or more. Therefore, in order to ensure the performance of the product, heat stabilizers need to be added during processing. Although PVC is a polymer with good electrical properties, its electrical insulation is not as good as PP and PE due to its large polarity. Dielectric constant, dielectric loss tangent, large volume resistivity, poor coronavirus resistance, suitable for medium and low voltage and low frequency insulation materials.

What is the price of PVC sheet above? In general, the price of the material this time is not fixed, and its brand, grade, color, etc. directly affect the selling price of the market. Therefore, when we buy, we should not only pay attention to the selling price, but should pay attention to the cost performance and whether the price is reasonable.
