1. Applications

2. Physical Properties of Rubber Cover (before aging)

Grade Tensile Strength/Mpa ≥ Breaking Elongation/% ≥ Abrasion Loss/mm³ ≤

H 24 450 120

D 18 400 100

L 15 350 200

Note: Grade H-used for transporting sharp, abrasive materials which can damage belts badly. Grade D-used for transporting highly abrasive materials.Grade L-used for transporting medium-abrasion materials.

After-aging properties of rubber cover(70℃×7d):

Tensile strength and breaking elongation are both not lower than 75% of before-aging values.

3. Adhesion

a. Adhesion between rubber cover and belt core: ≥12N/mm.

b. Adhesion of steel core (N/mm)
