Stiff and Soft Dipped Polyester Cord
Brief introduction:
1. They are divided into soft cords and stiff cords that are widely suitable in aviation, aerospace, sea, fire fighting, hose,auto V-belt and driving belts,etc.
2. Polyester soft cord is mainly used for producing V-belts. With the high quality polyester filament, rational twisting, unique dipping and heating process, the product has developed such advantages as high strength, low elongation, stable dimension,anti-fatigue, and good adhesion with rubber.
3. Polyester stiff cord is mainly used as the reinforcement of the edge-cutting V-belt and poly V-belt With the features of high strength, low elongation, and stable dimension, it is applicable to glue with vatious kinds of polymerization, proper hardness, and anti-faigue in the hardening treatment.
Specification:
4. Here we can mainly supply soft cord 1000D/2*3,1000D/3*3,1000D/2*5,1000D/4*3, 1000D/5*3,1000D/6*3,1000D/9*3,1000D/12*3,and stiff cord 1000D/1*3,1000D/2*3,1000D/3*3, 1000D/2*5,1000D/4*3,1000D/5*3,1000D/6*3,1000D/9*3,etc. We also can produce according to customers' requirements.
