PVC Fire Resistant Conveyor Belt
1. Applications
Solid woven fire resistant conveyor belt (PVC type)
澳门新葡新京The belt is mainly used in underground coal transportation, also in metallurgy and chemical industry. It is manufactured by plasticizing or vulcanizing solid woven core, which is impregnated in PVC paste.
2. Characteristics
-high tensile strength
-big-volume & smooth transportation
-good fire/static/impact/abrasion/corrosion resistance.
-transporting angle＜16 degree
