The 4x8 pvc foam board is a board with a honeycomb mesh structure made of PVC as raw material, and is used in many industries such as building materials, packaging, and medicine. According to the degree of softness and hardness, it can be divided into soft PVC and hard PVC. According to the production process, it can be divided into PVC skinned foam board and PVC free foam board.
In 2010, China's development momentum was strong, the economy was advancing by leaps and bounds, and the overall national strength was increasing day by day. Among them, the construction industry was particularly popular. As the leader in building materials, pvc panels set a record high in domestic sales and usage. This achievement mainly depends on pvc. The excellent characteristics and wide applicability of the board.

pvc board (coiled material): glossy and soft surface. There are brown, green, white, gray and other colors to choose from. The material used in this product is up to the city, the production is fine, and it is widely used. Performance characteristics It is soft and cold-resistant, abrasion-resistant, acid-resistant, alkali-resistant, corrosion-resistant, tear-resistant, has excellent weldability, and its physical properties are better than rubber and other roll materials. Used in chemical industry, electroplating, electrolytic cell lining, insulating cushion, train, automobile interior decoration and auxiliary materials.

PVC board performance: general performance 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 adding

Adjust the number of plasticizers. Pure PVC has very little water absorption and air permeability.

　　 Mechanical properties PVC has higher hardness and mechanical properties. It increases with the increase of molecular weight, but decreases with the increase of temperature. Rigid 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 factor is 0.4-0.5, and the dynamic friction factor is 0.23.

　　 Thermal properties PVC has very poor heat resistance stability. It starts to decompose at 140°C, and its melting temperature is 160°C. The linear expansion coefficient of PVC is small, it is flame retardant, and the oxidation index is as high as 45 or more.

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

　　Environmental performance PVC is resistant to most inorganic acids, alkalis, salts, and most organic solvents. Suitable for medicine and chemical antiseptic materials.
