OIL-PROOF
An oil-resistant compound is specially designed to withstand prolonged contact with oily substances, which can cause the belt to swell, a phenomenon that could affect the proper movement of the belt on the drums. These compounds are critical to minimize swelling and ensure effective belt movement in environments where oils are present.
Our belts with oil-resistant compounds are:
Typical Applications:
Recycling sector: Transportation of waste containing oily substances
Food industry: Transportation of oil-treated ingredients
Industry Sector: Handling of oil-impregnated materials
The benchmark for oil resistance in conveyor belts is generally related to DIN 22102, which establishes the characteristics and requirements for rubber belts. However, the specific test for oil resistance is often performed according to other technical standards, such as DIN 1817, which determines the volumetric swelling of the belt in the presence of ASTM 3 oil.
The test involves measuring the change in volume of rubber following contact with ASTM 3 oil, maintaining a constant temperature of 100°C for a period of 24 hours. The high temperature accelerates the natural aging process of the sample by simultaneously exposing it to the oil.
Next, the initial and final sample volumes are compared and the percentage of change is calculated:
Higher values in the test indicate lower resistance of the belt to oil, resulting in more swelling.
Lower values, on the other hand, signal greater oil resistance, resulting in less swelling.
