EP/NN Canvas

Using domestic and foreign advanced equipment to produce nylon (NN) canvas, polyester nylon (EP) canvas and rubber dam cloth. Among them, nylon canvas has higher strength and elasticity, and has better resistance to flexure and load impact; while polyester nylon canvas not only has the advantages of nylon canvas, but also has the advantages of high initial elastic modulus and good dimensional stability. . Polyester/nylon canvas, nylon canvas and rubber dam cloth have good adhesion to rubber after dipping process. They are ideal framework materials for rubber conveyor belts and rubber dams.
