Performance
The general properties of PVC resin is a kind of white or light yellow powder, relative density is 1.35-1.45. The hardness of the products may be added
PVC transparent plate
By the number of copies of plasticizer, the number of adjustment. Water absorption of pure PVC rate and permeability are rarely.
Mechanical properties of PVC hardness and high mechanical properties.And increased with increasing molecular weight, but decreases with the increase of temperature. The mechanical properties of rigid PVC, its elasticmodulus was 1500-3000MPa. While the soft elasticity of PVC 1.5-15 MPa.But the elongation at break up to 200%-450%. The friction of PVC general,static friction factor is 0.4-0.5, the friction factor is 0.23.
Thermal stability of thermal performance of PVC is very poor, 140 ¡æ begins to decompose, the melting temperature is 160 ¡æ. PVC linear expansion coefficient is small, is hard to burn, the oxidation index above 45.
The electrical properties of PVC polymer is a kind of good performance, butbecause of their high polarity, electrical insulation properties than PP and PE. The dielectric constant, dielectric loss tangent and volume resistivity is larger, corona resistance is not good, generally suitable for low pressureand low frequency insulating material.
The environmental performance of PVC resistant to most inorganic acid,alkali, salt, most organic solvents. Suitable for pharmaceutical, chemical anti-corrosion material.
