CORDENKA has been producing industrial yarns since 1928. This experience in reinforcement - along with a extensive tradition of thorough testing - has shown CORDENKA^® reinforcement for rubber and rubber goods to not only offer uncommonly high chemical resistance and low thermal shrinking, but also properties during vulcanization which make it superior to and more cost-effective than competing materials.

Polyester and polyamide are based on oil; that means they are thermoplastic and therefore affected by heat and stress. They exhibit higher shrinkage, higher elongation, and more creep.

CORDENKA^® rayon, on the other hand, owes its heat- and stress-resistance to its cellulose origin. Rayon is thermostable, which means that it is hardly affected by heat and stress and offers lasting dimensional stability and performance.

In addition, CORDENKA^® rayon requires no additional activating step (isocyanates) prior to RFL dipping. That's not only better for manufacturing budgets, but - along with the fact that CORDENKA^® fibers are produced from renewable raw materials - it's better for the environment as well.

Product properties of CORDENKA^® include:

• good adhesion to rubber and plastics
• high heat ageing and chemical resistance
• high modulus
• high thermal stability
• high dimensional stability
• low hysteresis
