PVC sheet has been gradually used by people in the cabinet, bathroom cabinet, etc., but how much do you understand the unique performance and classification of PVC board? The following is a detailed introduction,  you can learn more about the PVC sheet.

Mechanical properties. PVC has 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.

PVC board for temperature: -50 ℃ -70 ℃

Tensile strength: 29.4mpa

Flexural strength: 45.6mpa

Low temperature (-5  ℃ drop hammer impact): 10 times zero broken.

Color: White

Life: not less than 50 years.

Plate classification:

According to the molecular weight of PVC can be divided into general and high degree of polymerization and two types.

According to the degree of soft and hard, can be divided into soft PVC and hard PVC.

According to the production process, PVC foam board can be divided into PVC crust foam board and PVC free foam board.
