Fire Resistant Steel Cord Conveyor Belt

Introduction of Fire Resistant Steel Cord Conveyor Belt
This range of steel cord conveyor belt is a kind of fire resistant conveyor belt which employs galvanized steel wire rope with high strength and low elongation as the carcass. Both upper and lower rubber layers are flame-retardant and anti-static, making the product an ideal choice for heat resistant belt.

With the same structure as general purpose steel wire conveyor belt, our steel cord conveyor belt has higher strength, and can smoothly convey heavy loads. Besides that, the steel wire reinforced rubber conveyor belt is resistant to abrasion, corrosion, impact, and so on.

After the aging test, average bond strength of steel wire rope is no less than 85% of that before aging test. The average bond strength between covering layer and bonding layer is ≥10KN/m. As for flame retardant steel cord belt with fabric layer, the average adhesive strength between covering layer and fabric layer is ≥8KN/m.

Application
Our fire resistant steel cord conveyor belt is suited for the long-distance, speed conveying of a large amount of materials in the areas where fire prevention and explosion proofing are required.
