Nipol ® NBR Elastomers
Polyblends and Pre-Plasticized Nitrile
Nipol Polyblends are specifically designed to provide improved ozone and abrasion resistance. Nipol 1082V has found a primary niche market for making soft 25 to 35 Shore A printing rolls and other low hardness calendered and molded goods.
Sivic Polyblends are mechanically blended, fully fluxed, and screened to produce a polymer with the highest degree of purity and uniformity. Sivic Polyblends provide excellent fuel and ozone resistance and are used to produce a variety of products, including printing rolls, hose, conveyor belts, cable jackets and shoe soles. |

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.
