Solid woven fire resistant conveyor belt is manufactured by plasticizing or vulcanizing solid woven core, which is impregnated in PVC paste. The belt has below characteristics: high tensile strength, big-volume & smooth transportation, good fire/static/impact/abrasion/corrosion resistance.
The product is mainly used in underground coal transportation, also in metallurgy and chemical industry.
PVG type has top & bottom cover made from NBR & PVC. Each cover≥1.5mm-4.5mm, transporting angle＜20°.
