1. Applications
Fire resistant conveyor belt is suitable for transporting non-corrosive, not sharp, lump, granular, powdery materials in flammable and explosive environment on the ground. It applies to power plant, coal mine, chemical industries.
2. Physical Properties of Rubber Cover (before ageing)
Grade  Tensile Strength/Mpa ≥  Breaking Elongation/% ≥  Abrasion Loss/mm3 ≤
D  17  450  175
L  14  400  200
Note:Grade D-used for transporting highly abrasive materials.Grade L-used for transporting medium-abrasion materials.
After-ageing properties of rubber cover(70℃, 7days):
Tensile strength and breaking elongation are both not lower than 75% of before-ageing values.
3. Ply adhesion
