Nn Conveyor Belt

Model NO.: IR-B Material: Rubber Feature: Oil-Resistant, Acid And Alkali Resistant, Tear-Resistant, Heat-Resistant, Cold-Resistant, Wear-Resistant Width: 800mm~3200mm Top Cover Thickness: 3mm~6mm Trademark: Iron&steel Origin: China Type: NN500 Inside Material: Polyester Tensile Strength: Strong Fabric Type: Nn100~Nn400 Bottom Cover Thickness: 1.5mm~3mm Specification: ST1000~ST5400 HS Code: 40101200 NNConveyor Belt
Application
n   Available for conveying of bulk materials and baggage,meanwhile, the belt is widely used in cement industry, coal mines, foundries,grain industry, quarries, sandpits, wood industry, steel industry, etc. 
Advantage
 n  High modulus and highresistance to tension
n  Impactresistance and good troughability
The carcass is NN canvas(both the warp and the weft are Nylon fabric). Compared with the EP belt, theNN belt carries the advantages of light weight, high modulus, good impact resistance,low elongation, good elasticity and good troughability.  It is suitable for transportation in mediumor long distance under conditions of big impact and heavy abrasion.
