The whole core fire-retardant conveyor belt is made from the whole belt core via dipping and plastify in polyvinyl chloride (PVC) dipping agent or sulfuration. It is mainly applicable for the underground well haulage of coal mines, and also the conveyance of materials for metallurgical and chemical industries, The whole core fire-retardant conveyer belt is divided into two types: PVC, PVG. Flame resistant property (1)Roller friction：The roller surface temperature is not more than 325℃ (2)Blowtorch burning(with cover) ： the average duration of flame for six samples≤3s; the duration of flame for any individual sample ≤10s. (without cover): the average duration of flame for six samples≤5s; the duration of flame for any individual sample ≤15s. Propane burner the length completely undamaged ≥ 250mm Surface electricity resistance value The average electrical resistance of both surfaces ≤3.0×108Ω Safely performance It has been passed the flame retardant test and static test and got the safety Certificate of approval for mining products. Mechanical properties It can provide users with long service life and economic installation . The longest service life factors:entire core was made by warp weft filament and cover cotton woven ; dip on the special formula of pvc to make the between of core and rubber cover to reach the high adhesive strength ; special formula rubber cover .
