Physical Properties of Rubber Cover (before aging) of EP Nylon Conveyor Belt
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(70ºC, 7days):
Tensile strength and breaking elongation are both not lower than 75% of before-aging values.
Full-thickness Tensile Properties
a. Longitudinal tensile strength, not less than the below table. (N/mm)
