HG/T 3714-2014 “Oil-resistant conveyor belt”
Covering glue standard
Physical properties of oil resistant conveyor belt cover | |||
Performance Type | Tensile Strength/Mpa | Elongation at break/% | Wear/mm³ |
LO | ≥14.0 | ≥350 | ≤200 |
DO | ≥16.0 | ≥350 | ≤160 |
Note: LO is the oil-resistant conveyor belt under normal conditions; DO is the conveyor belt under strong wear-resistant and oil-resistant working conditions. |
