General performance
PVC resin is a white or light yellow powder, the relative density of 1.35-1.45.
PVC transparent board
The number of plasticizer parts to adjust. 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.
You have to look at the comparison of acrylic and PVC materials:
1, acrylic material transparency is PVC and PC do not have the. Advantages: transparency was significantly higher than other materials, good processing performance Disadvantages: Acrylic easy to scratch, fragile.
2, PVC material: easy processing, impact resistance than high acrylic. Advantages: not easy to burn the role of flame retardant. Impact resistance is higher. Disadvantages: transparency is not high. Bluish blue
3, PC material: hardness, than the price of PVC and acrylic high. Advantages: impact resistance and high temperature resistance. Explosion-proof effect. Disadvantages: high hardness, not easy to process.
