General performance



PVC resin is a white or pale yellow powder, and its relative density is 1.35-1.45. The hardness of the products can be adjusted by adding the number of copies of the plasticizer. The water absorption and breathability of the pure foam boards are poor.

Mechanical properties of PVC board



PVC has high hardness and mechanical properties, and increases with the molecular weight, but decreases with the increasing temperature. The mechanical properties of rigid PVC is excellent, the elastic modulus is up to 1500-3,000MPa, while the elasticity of soft PVC is 1.5-15MPa. However, the elongation at break up is to 200% -450%. The friction of PVC is not so good. The static friction factor is 0.4-0.5, and the dynamic friction factor is 0.23.

Thermal Properties



The heat stability of PVC is very poor, it starts to decompose at 140 ℃, and its melting temperature is 160 ° C. The coefficient of linear expansion of the PVC is small with the flame resistance, and the oxidation index is up to 45 or more.

Electrical properties

PVC is a polymer with the better electrical properties, but due to the polar itself, the electrically insulating is worse than PP and PE. Dielectric constant and dielectric loss tangent value and volume resistivity is large, and corona resistance is bad, generally is suitable for medium and low voltage and low frequency insulation materials.

Environmental performance

PVC trim board is resistant to most inorganic acids, alkalis, salts and most organic solvents. It is suitable for pharmaceutical and chemical anti-corrosion materials.

Advantages of PVC board

First of all, this is a completely waterproof material, because it is plastic, it is widely used in the place of the outside balcony, Plank Road, a swimming pool, lake, beach, ship deck and so on.

Secondly, this is a completely anti-termite, anti-moth-eaten material, because it does not contain fibrin.

Third, this is a material with good performance of a flame retardant. We have done experiments in the natural environment, pour the gasoline on PVC micro-foaming floor, and then ignited. Gasoline burn and fire is extinguished in one minute without dark fire and smoke in 2 seconds. Excellent fire retardant properties cannot be compared with wood or wood-plastic materials.

Fourthly, this material does not decay, is radiation-free and non-toxic, in line with national testing standards. It is maintenance-free without maintenance of pollution.

Fifth, the bending resistance and the surface hardness of this material are higher than that of wood and wood plastic materials. Its nail-holding ability is stronger than the wood-plastic and the same with wood.
