Pvc sheet polyvinyl chloride (PVC) plastic is a polymer obtained by free radical polymerization of vinyl chloride monomer, the English name polyviny chloride, referred to as PVC. PVC can be divided into soft PVC and hard PVC. Hard PVC accounts for about 2/3 of the market, and soft PVC accounts for 1/3.
Soft PVC is generally used for the surface of floors, ceilings and leather. However, soft PVC contains a softener, which is easy to become brittle and difficult to store, so its use range is limited. Hard PVC does not contain softener, has good flexibility, is easy to form, is not brittle, non-toxic and non-polluting, and has a long storage time, so it has great development and application value.
PVC foam board has anti-corrosion, moisture-proof, mildew-proof, non-absorbent, drillable, sawable, planable, easy thermoforming, hot bending processing, etc., so it is widely used in furniture, cabinets, bath cabinets, display racks, Box core layer, indoor and outdoor decoration, building materials, chemical and other fields, advertising signs, printing, silk screen, inkjet, computer lettering, electronic instrument product packaging and other industries.
PVC hard plastic board has excellent corrosion resistance, insulation and certain mechanical strength; after secondary processing, it can be made into sulfuric acid (hydrochloric acid) tank (barrel box); medical empty needle holder, chemical processing frame; public Bathroom water tank; processing products, stencils, decorative panels, exhaust ducts, equipment linings and other special-shaped products and containers. It is an ideal material for chemical, building materials, decoration and other industries.
In the late 1960s, he relegated to second place. Due to the abundant raw materials for PVC resin synthesis, the demand for low prices has increased rapidly, and its status has gradually strengthened. The average polymerization degree of general-purpose PVC is 500~~150, and the average degree of polymerization of high-polymerity PVC is more than 1700. Our commonly used PVC resins are all versatile.
General properties PVC resin is a white or light yellow powder with a relative density of 1.35 - 1.45. The hardness of the product can be added by

The number of plasticizers is adjusted. Pure PVC has low water absorption and gas permeability.
Mechanical properties PVC has high hardness and mechanical properties. And it increases with the increase of molecular weight, but decreases with the increase of temperature. The mechanical properties of rigid PVC are good, and its elastic modulus can reach 1500-3000MPa. The soft PVC has an elasticity of 1.5-15 MPa. However, the elongation at break is as high as 200%-450%. The friction of PVC is generally, the static friction factor is 0.4-0.5, and the dynamic friction factor is 0.23.
Thermal properties The thermal stability of PVC is very poor, starting to decompose at 140 ° C, the melting temperature is 160 ° C. PVC has a small coefficient of linear expansion, is flame retardant, and has an oxidation index of up to 45 or more.
Electrical properties PVC is a polymer with good electrical properties, but due to its large polarity, electrical insulation is not as good as PP and PE. Dielectric constant, dielectric loss tangent and volume resistivity are large, corona resistance is not good, generally suitable for medium and low voltage and low frequency insulation materials.
Environmental properties PVC is resistant to most inorganic acids, bases, salts, and most organic solvents. Suitable for medicine, chemical anti-corrosion materials.
