PVC plastic sheet  

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.  The nature of PVC is a vacuum blister film, used for the surface packaging of all kinds of panels, so it is also known as decorative film, attached film, used in building materials, packaging, medicine and many other industries.  Among them, the building materials industry accounts for the largest proportion, 60%, followed by the packaging industry, and a number of other small-scale application industries.  

PVC hard plastic board has excellent corrosion resistance, insulation, and a certain mechanical strength;  After the secondary processing can be made into sulfuric acid (hydrochloric acid) tank (bucket box);  Pharmaceutical empty needle frame, process frame;  Public toilet water tank;  Processing products of templates, decorative boards, exhaust pipes, equipment lining and other special-shaped products, containers.  It is an ideal material for chemical industry, building materials, decoration and other industries.  

PVC board performance  

General properties PVC resin is a white or yellowish powder with a relative density of 1.35-1.45.  The degree of softness and hardness of the product can be added  

The number of plasticizers to adjust.  Pure PVC water absorption and permeability are very few.  

Mechanical properties PVC has higher hardness and mechanical properties.  It increased with the increase of molecular weight, but decreased with the increase of temperature.  Hard PVC has good mechanical properties, and its elastic modulus can reach 1500-3000MPa.  The elasticity of soft PVC is 1.5-15 MPa.  But the elongation at break is as high as 200%-450%.  The friction of PVC is general, the static friction coefficient is 0.4-0.5, the dynamic friction coefficient is 0.23.  

Thermal properties of PVC heat resistance stability is very poor, 140ºC that is, began to decompose, melting temperature of 160ºC.  PVC linear expansion coefficient is small, with flammability, oxidation index up to more than 45.  

Electrical properties PVC is a polymer with good electrical properties, but due to its greater polarity, the electrical insulation is not as good as PP and PE.  The dielectric constant, dielectric loss Angle tangent value and volume resistivity is large, corona resistance is not good, generally suitable for low and medium voltage and low frequency insulation materials.  

Environmental performance PVC can be resistant to most inorganic acids, alkali, salt, most organic solvents.  Suitable for medicine, chemical anticorrosive materials.
