Fire-resistant PVC board is a board with a honeycomb mesh structure made of PVC as raw material.
Fire-resistant PVC panels account for the largest proportion in the building materials industry at 60%, followed by the packaging industry, and there are several other small-scale applications. 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. According to transparent and opaque, it can be divided into PVC transparent board and pvc board.
The scientific name of PVC is polyvinyl chloride. It has fire resistance, but it can burn.
The combustion of polyvinyl chloride is divided into two steps: firstly, it is burned at 240℃-340℃ to decompose hydrogen chloride gas and diene containing DAO with double bonds, and then carbon combustion occurs at 400-470℃. During the combustion process, hydrogen chloride and other toxic gases such as dioxins are released.
Polyvinyl chloride can be made by substitution reaction of ethylene, chlorine and catalyst. Due to its fire and heat resistance, PVC is widely used by PVC board manufacturers for various products in all walks of life: wire sheaths, fiber optic sheaths, shoes, handbags, bags, accessories, signs and billboards, construction and decoration supplies, furniture , Ornaments, rollers, pipes, toys, curtains, rolling doors, auxiliary medical supplies, gloves, etc.
