PVC Board Performance
Aug 18, 2017

General performance PVC resin is a white or light yellow powder, the relative density of 1.35-1.45. The degree of softness and hardness of the product can be adjusted by adding the number of parts of the plasticizer. Pure PVC water absorption and permeability are few.

Mechanical properties PVC has a high hardness and mechanical properties. And increased with the increase of molecular weight, but with the temperature rise. Hard PVC mechanical properties, and its elastic modulus up to 1500-3000MPa. While the soft PVC elasticity of 1.5-15 MPa. But the elongation at break up to 200% -450%. PVC friction in general, static friction factor of 0.4-0.5, dynamic friction factor of 0.23.

Thermal properties of PVC heat stability is very poor, 140 ℃ began to break down, the melting temperature of 160 ℃. PVC linear expansion coefficient is small, with flame retardant, oxidation index of up to 45 or more.


Electrical properties PVC is a good electrical properties of the polymer, but because of its large polarity, electrical insulation than PP and PE. Dielectric constant, dielectric loss tangent and volume resistivity, resistance to corona is not good, generally suitable for low pressure and low frequency insulation materials.

Environmental performance PVC can withstand most of the inorganic acid, alkali, salt, most organic solvents. Suitable for medicine, chemical anti-corrosion materials.
