PVC/PVG Fire retardant Conveyor Belt
PVG Fire retardant Conveyor Belt
Solid woven fire resistant conveyor belt is manufactured by plasticizing or vulcanizing solid woven core, which can be divided into PVC type and PVG type. For the PVC type, both the top cover and bottom cover is PVC rubber cover, which is impregnated in PVC paste, with the coating plastic thickness of ≥0.8mm and at slope angle of <16°; For the PVG type, both the top cover and bottom cover is rubber blends PVC, with the coating rubber thickness of 1.5~4.5mm,and at a slope angle of <20°.
It is mainly used in underground coal transportation, metallurgy and chemical industry.
