Product Description: whole core flame retardant conveyor belt is mainly used in coal mine.
Features of the belt: no delamination, small elongation, impact resistance and tear resistance. It can be divided into PVC type (plastic surface) and PVG type (adding rubber surface on the basis of PVC) whole core flame retardant belt according to the structure, and the implementation of MT / 914-2002.
PVC type is suitable for material transportation under dry condition with inclination angle below 16 degrees.
PVG type is suitable for conveying wet and watery materials with inclination angle below 20 degrees.
