Oil-resistant conveyor belts are made of cotton canvas, nylon canvas, polyester canvas, and are refined through processes such as calendering, molding, and vulcanization. They have relatively good oil resistance and are suitable for conveying oil-containing materials and some situations where oily and chemical solvents may occur. The belt thickness reaches the standard, the tensile strength is high and it is not easy to stretch and deform. The conveyor belt has high adhesion between layers, good groove formation and long service life. Among food conveyor belts, the most widely used oil-resistant conveyor belt is PU conveyor belt.
