Crumb and Powdered NBR

Kramod ^® High performance Crumb and
Powdered Nitrile Butadiene Rubber

The Crumb and Powdered NBR is widely used as elastomer modifier or binder for rubber and plastic composites, spanning different industries and markets

A compatible additive for soft PVC to improve swelling and impact resistance and to provide an excellent plasticizing effect

In fact, indispensable for effective PVC extrusion

A base polymer that can easily get solved in polar solvents to enable production of gaskets for automotive and industrial use. The resulting part will show excellent set properties at high temperatures

A component in brake pads and linings for a reliable braking action

A part in solvent-based adhesives

A modifier for phenolic-, melamine- and epoxy resins to improve the impact resistance thus reinforcing the duroplastic material

An improver for the comfort and lifetime of shoe components

Product Advantages

Good abrasion resistance

Low fogging

Better impact resistance

Low plasticizer volatility and low precipitation

Good mechanical properties

Good low temperature resistance,etc
