Widely used in coal mining and delivery under coal mine, the rubber type is specially suitable for the circumstances with high delivery angle due to its large friction coefficient. Adopt polyester/cotton weaving high force whole fabric as belt core,covering layer is made of rubber, plastic or PVC resin and other anti flaming materials. Divide into rubber type,plastic type and full plastic type according to the characteristics of covering layer. Have light belt body, high strength, no delaminating, good safety performance and other features.Physical and Mechanical Properties:
