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.
Although oil resistant belts usually have a lower resistance to cold, Fenner Dunlop oil resistant belts are designed to operate in cold temperatures as well.
