Features and Applications

The cover rubber of the oil-resistant conveyor belt is primarily made from nitrile rubber with a high acrylonitrile content, and its carcass layer consists of cotton canvas, nylon canvas, or EP canvas. This belt boasts advantages such as low volumetric change, high strength retention, and a wide range of applications. It is suitable for conveying oil-containing materials or for use in environments where it may come into contact with various types of working oils (excluding fuel oils or solvent oils).
