The top and bottom layers of the flame-retardant PVC conveyor belt are all PVC coated, the thickness of the single-sided tape is ≥1.0mm, and the inclination angle: <16°. PVC is actually a kind of vinyl polymer, and its material is an amorphous material. In actual use, PVC materials often add stabilizers, lubricants, auxiliary processing agents, pigments, impact resistance agents and other additives. It has non-flammability, high strength, weather resistance and excellent geometric stability.
Flame-retardant PVC conveyor belt is a more practical product in the coal mine transportation industry today, and it is also one of the widely used conveyor belt types. In addition to being used in coal mines, the product can also be used in metallurgy and chemical industries. The product has the characteristics of non-delaminating, low elongation, impact resistance and tear resistance.
Flame-retardant PVC conveyor belts have strong resistance to oxidants, reducing agents and strong acids. However, it can be corroded by concentrated oxidizing acids such as concentrated sulfuric acid and concentrated nitric acid and is not suitable for contact with aromatic hydrocarbons and chlorinated hydrocarbons. With the popularization of the PVC conveyor belt market becoming more and more mature, various industrial fields are developing and applying its reasonable, scientific, and secure constructive solutions to varying degrees.
