PVC/PVG fire retardant conveyor belt
Usage:
It is mainly applicable for underground well haulage of coal mines, and also the conveyance of materials for metallurgical and chemical industries, The whole core fire retardant conveyor belt is divided in to Type: PVC, PVG.
PVC type conveyer belt's upper and lower layers are PVC coating cover, single-sided tape thickness: ≥ 1.0mm; PVG type belt's upper and lower layers are nitrile rubber and PVC, single-sided tape thickness: 1.5mm-4.5mm.
PVC type conveyer belt's inclined angle: <16° ;
PVG conveyer belt's inclined angle: <20° .
