The covering rubber layer of the oil resistant conveyor belt uses the NBR rubber with high content of acrylonitrile and uses cotton , nylon or EP as the strong layer, which is suitable for transferring oily materials or some kinds of oily condition (excluding fuel and solvent oil).
It has the advantage of Iow changing rate of volume, high intensity conservation rate, wide range of use.

The physics and mechanical properties of the oily conveyer belt covedng layer rubber are as mentioned in the following table:
| Type | Break the intensity /Mpa | Break extension rate /% | Wearing and tearing /mm3 |
| LO | ≥14.0 | ≥350 | ≤200 |
| DO | ≥16.0 | ≥350 | ≤160 |
| Notes: LO--Oily conveyer belt under the general condition; DO--Conveyer belt under the shock resistant and oily condition. | |||
| Oil proof performance of the oil proof conveyer belt covering layer is as mentioned in the following table: |
| Serial number | Experimental condition in soaking the liquidm | Rate of change of the volume /%≤ | |||
| Oil number in GB/T1690 | Soaking temperature /℃ | Soaking time /h | LO | DO | |
| 1 | Oil No.2 | 70±2 | 70-0/1 | 20 | -5 |
| 2 | Oil No.3 | 70±2 | 70-0/1 | 50 | 5 |
| 3 | Oil No.3 | 100±2 | 22±0.25 | 50 | 5 |
| Notes:one of oil proof testing is ok. | |||||
