The mechanical properties of PVC are characterized by its high hardness. These properties tend to increase as the molecular weight of PVC increases. However, they decrease as the temperature rises. Specifically, rigid PVC exhibits excellent mechanical properties, with a modulus of elasticity ranging from 1500 to 3000MPa. On the other hand, soft PVC has an elasticity ranging from 1.5 to 15 MPa. When it comes to friction, PVC has a static friction coefficient of 0.4-0.5 and a dynamic friction coefficient of 0.23. As for PVC boards, they can be categorized into three types: PVC hard boards, PVC soft boards, and PVC transparent boards.
PVC hardboard is characterized by its smooth and flat surface, with no cracks or bubbles. Its color options include grey and white, as well as the possibility of producing blue, black, and computer colors. This versatile material finds application in the production of various chemical equipment due to its exceptional resistance to acid and alkali. It is extensively used in industries such as chemical processing, electroplating, smelting, and water treatment. Moreover, PVC hardboard has gained popularity in the building and decoration material sector, where it is used as a template. The demand for PVC board in this industry is substantial. However, it is worth noting that PVC hardboard is not suitable for food containers.
A flexible plate made from PVC is created using extrusion techniques, and infused with plasticizer and other additives. This results in a pliable sheet that is perfect for a range of applications.
The soft board has a sleek surface with a texture that is soft yet durable. The color scheme of the board consists of shades of white, green, red, grey, and black.
This material is perfect for applications that require protection against acid and alkalis, as well as resistance to corrosion. It is commonly used to line equipment, but can also serve as electrical insulation or sealing gaskets. Its operating temperature range is between -20°C and 40°C.
The transparent rigid board made of PVC boasts a smooth surface and is equipped with flame retardant properties. Along with being an excellent insulation material, it also possesses moisture-proof, heat insulation, and anti-corrosion attributes. Its impact resistance ensures that it remains free from any deformation, while its light resistance and anti-fading features contribute to its longevity. Moreover, it exhibits remarkable weather resistance. Due to these exceptional qualities, it finds extensive applications in shock-proof containers, anti-corrosion equipment, and protective covers for electrical appliances. It is also utilized in lamp boxes, building materials, hardware decoration, and both interior and exterior decoration projects.
The PVC transparent soft board boasts of a sleek surface that is free from cracks, bubbles, and discoloration. With its resistance to extreme temperatures, aging, and mechanical stress, this board is ideal for both domestic and industrial use. It is commonly used in shops, factories, and malls to create door curtains, aisle decorations, and tabletops with excellent light transmission properties. Above all, its durability ensures users enjoy its service for a prolonged period.
