Nipol ® NBR Elastomers
Specialty Elastomers - POWDERS
Nipol NBR is produced in a variety of powder and crumb forms with mineral or PVC partitioning agent. The ground crumb and powder forms provide for ease of solubility in adhesive and sealant applications. Nipol 1411 is a very fine crosslinked powder, ideal for phenolic resin modification and is widely used in the friction industry. Zealloy polymer modifiers are designed exclusively for thermoplastic modification and are effective in providing flexibility and impact resistance in PVC formulations. |

Preplasticized Nipol 1082V has found a primary niche market for making soft 15 to 35 Shore A printing rolls and other low hardness calendered and molded goods. Carboxylated Nipol NX775 is used in high abrasion applications, such as hose covers, oil well drilling parts, high modulus wear seals and premium footwear soles.

|
The present generation of cold Nipol NBR elastomers spans a wide variety of compositions. Acrylonitrile contents range from 19% to 51%. Mooney values for bale Nipols range from a tough 110 to pourable liquids.
|
|
Hot polymerized Nipol elastomers are highly branched and are excellent for thin walled or complex extrusions. They are also ideal for solvent-based adhesives. The combination of low gel content and high degree of branching encourages good tack and a strong bond.
