Structure
It is made from the whole core via dipping and plastifying in polyvinyl chloride(pvc) dipping agent or sulfuration. Besides that, it is fire retardant, ant-static, shock resistant, abrasion resistant and corrosion resistant.
Application
It is mainly applicable for the underground well haulage of coal mines, and also the conveyance of materials for metallurgical and chemical industries. it features largely in the high strength, large freight volume and stable conveyance performance.
Type
This kind of conveyor belt is divided into two types: PVC and PVG.
PVC type conveyor belt's top and bottom layers are PVC coating cover, Single-sided tape thickness ≥1.0mm, inclined angel:<16°.
PVG type conveyor belt's upper and lower layers are nitrile rubber and PVC, which have the feature of TPE. single-sided tape thickness: 1.5mm-4.5mm, inclined angel:<20°
