Industrial Conveyor Belts
Nylon (NN) Fabric Belt
The NN belt employs nylon fabric plies as its carcass for the short- to medium-distance transportation of non-corrosive, non-abrasive bulk and unit materials such as coal, coke, sand, gravel, and cement across sectors including chemical, electricity, metallurgy, light industrial, food processing, and coal mining.
Key Advantages
- Excellent elasticity delivers outstanding flex and impact resistance under continuous load, cushioning the shock of falling material and extending belt life.
- A soft, elastic nylon carcass gives excellent troughability under both empty and heavy loads, keeping material flow steady and tracking true.
- Naturally water-, corrosion-, and mildew-resistant, for reliable performance in harsh conditions.
- Strong fatigue resistance resists inter-ply separation, blistering, and cracking, making the belt highly adaptable to small- and medium-diameter pulleys.
