Basic Product Description
NN conveyor belt has the characteristics of thin belt, high strength, impact resistance, good grooving, strong interlayer adhesion, excellent flexibility and long service life. It is suitable for conveying materials under medium-long distance, high load and high speed conditions. It is widely used in mining, coal yard, chemical industry, metallurgy, construction, port and other departments.
Characteristic：
1、The belt has good elasticity, impact resistance and wear resistance.
2、Good flexibility and easy grooving.
3、No mildew occurs.
