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)
| Nominal belt type | 160 | 200 | 250 | 315 | 400 | 500 | 630 |
| 800 | 1000 | 1250 | 1600 | 2000 | 2500 | 3150 |
b. Full thickness, longitudinal elongation at reference force, not more than 4%.
c. Ply adhesion:
| Item | Ply to ply | Rubber cover to ply | |
| Rubber cover thickness ≤1.5mm | Rubber cover thickness >1.5mm | ||
| All samples average value/ (N/mm) ≥ | 4.5 | 3.2 | 3.5 |
| All samples min peak value/ (N/mm) ≥ | 3.9 | 2.4 | 2.9 |
| Note: All samples max peak value is not more than 20N/mm. | |||
d. Straightness not more than 25mm
