NN conveyor belt:

The basic strength material is NN fabric (warp and weft all in polyamide). The belt has all the advantages of EP belt except a bigger working elongation than EP belt.

EP conveyor belt:

The basic strength material is EP fabric (warp-polyester, weft-polyamide). The belt has many advantages such as high strength in proportion to weight, high resistant to impact, negligible elongation, great flexibility and trough ability, nonsusceptible to humidity and micro-organisms.

CC conveyor belt:

Cotton fabric is used in both warp and weft, but it is being displaced by synthetic materials.
