Oil resistance

Conveying materials that contain oil, fat, and grease can have a very detrimental effect on the performance and life expectancy of a conveyor belt because it penetrates into the rubber causing it to swell and distort, resulting in serious running problems. In order to achieve the absolute minimum of swelling and distortion caused by oil, even on the most demanding of applications, we apply stringent American ASTM’D’ 1460 standard test methods.

Oil-resistance can be divided into two sources – mineral oil and vegetable and animal oils. Despite the different characteristics, most manufacturers produce only one oil resistant rubber cover quality compound whereas we have developed two compounds to provide the best possible protection against those differing needs.

Dunlop ROM

Dunlop ROM is specifically designed to resist the penetration and damaging effects of animal and vegetable oils. In the case of highly aggressive mineral oils, our engineers have also developed the extremely successful Dunlop ROS cover quality.

In situations that involve products with high concentrations of animal and vegetable oils we strongly recommend the use of the superior resistance provided by the ROS cover grade quality. Dunlop BV ROM and BV ROS cover grades are both oil and fire resistant. Although oil resistant belts usually have a lower resistance to cold, Dunlop ROM and ROS oil resistant belts are designed to operate in temperatures as low as minus -20°C.

A QUICK REFERENCE GUIDE TO DUNLOP OIL RESISTANT COVERS

Dunlop ROM: oil and fat resistant for most products with animal and vegetable oils and fats.

Dunlop ROS: oil and fat resistant for products containing mineral oils.

BV ROS: oil resistant for animal and vegetable oils and fire resistant (K/S grades).

BV ROM: oil resistant for mineral oils and fire resistant (K/S grades).
