PVC board is PVC as the raw material of section structure of honeycomb mesh plate is a vacuum membrane for various types of panel surface packaging. General performance PVC resin as a white or light yellow powder, the relative density of 1.35-1.45. The degree of the product can be adjusted by adding a number of the number of plasticizer. Pure PVC water absorption and permeability are very few.
So what about the four performance of the PVC board? The mechanical properties of PVC have high hardness and mechanical properties. And with the increase of molecular weight, but with the increase of temperature and decrease. The mechanical properties of hard PVC are good, and its elastic modulus is 1500-3000MPa. And soft PVC 1.5-15 MPa. But the elongation at break is 200%-450%. PVC the friction of the general, the static friction factor is 0.4-0.5, the dynamic friction factor is 0.23.
The thermal stability of PVC was very poor, and the thermal stability of was 140. The linear expansion coefficient of PVC is small, and the oxidation index is 45 higher than that of the flame.
Electrical performance PVC is a kind of polymer with good electric property, but because of its high polarity, electrical insulation is not as good as PE and PP. Dielectric constant, dielectric loss angle tangent value and volume resistivity greater resistance to corona is not good, generally suitable for low voltage and low frequency insulating materials.
The environmental performance of PVC is resistant to most inorganic acid and alkali, salt, most organic solvents. Suitable for medicine, chemical anti-corrosion materials.
