Rubber & Polyblends
CHEMIGUM® N and NX Nitrile Rubbers
Chemigum®N NBR Bale and NX Carboxylated NBR Rubbers are the most cost-effective product lines of oil-resistant synthetic rubbers used in a myriad of automotive and industrial applications. A wide range of grades is available to combine the best of oil & fuel resistance, mechanical properties and performance at low temperatures with processing needs.
Range of NBR Bale. Hot and Cold, Batch & Continuous polymerized grades varying in ACN content, Mooney Viscosity and other features such as low mold fouling and plasticizer extended grades.
NX grades are particularly suitable for use in tough service conditions.

CHEMIGUM® NVC Polyblends (NBR/PVC)
The Polyblends are used where, in addition to oil & fuel resistance, superior weatherability, in particular resistance to ozone, is required. Grades differ in the type and content of the NBR rubber to adapt to specific combinations of performance, service environment and processing.
Range of Polyblends of NBR with PVC supplied in sheet form of varying thickness. Granular form can be supplied on demand.
