FLAME RETARDANT AND OIL RESISTANT CONVEYOR BELT

Oil-resistant and flame-retardant conveyor belts play an important role in conveying special materials such as grain and oil. Due to the particularity of the conveying material, the material is not only greasy, but also flammable. The conveyor belt adopts special nitrile rubber, which has excellent oil resistance, and is added with a composite flame retardant, which greatly improves the oil resistance and flame retardancy.
