Manufacturer of Rubber Conveyor Belt at China

NN nylon canvas conveyor belt

Nylon canvas conveyor belt is one of the best quality synthetic fibers in the rubber industry use nowadays. The nylon canvas is woven by nylon fibers both in warp and in weft. It is the most widely used fabric in rubber industry. And its outstanding merits are its high abrasion resistance,high tensile strength and good fatigue resistance.

Conveyor belts with nylon canvas inside have the characteristics of thin belt body ,high tensile strength,good shock resistance,good trough ability,high adhesion between plies,splendid flexibility and long working life.

Nylon conveyor belts are suitable for medium,long distance and heavy-load transportation of materials. Widely used in mining ,metallurgical industry and architectural industry ports
