Heat Resistance to 125°C
ZEON offers a full line of acrylonitrile butadiene polymers (NBR) for both general purpose and specialty applications. Nipol NBR elastomers offer the best balance of performance and cost for applications requiring the most severe oil, heat, and chemical resistance. 
Broad Offering of Acrylonitrile Content
By varying the acrylonitrile (ACN) content, a good balance of low temperature performance and fuel resistance can be achieved. Nipol NBR is offered at ACN levels ranging from 19% to 50%. 
Diverse Portfolio of Products
Nipol NBR elastomers are available in a variety of grades.?Not only do the products cover a wide range of ACN levels, but they can be further categorized based on processability (Mooney viscosity) or by differences in polymerization chemistry. Nipol NBR elastomers can be segmented into hot polymers, NBR/PVC, pre-crosslinked grades, carboxylated grades, and more. Nipol NBR elastomers are also available in a variety of forms (powder, crumb, liquid, and bale).

| 1034-60 | 21 | 55-70 | 0.95 | C | Staining (SS) |
Adhesives
Hot polymers are traditionally used in adhesives because they have a highly branched microstructure. This results in increased entanglements between polymer chains, which in turn imparts better heat resistance and grip to the adhesive. Many of the baled adhesive grades are also available in a crumb form to ease the solvation process.

Processing Aids
Nipol 1312 and Nipol 1312LV have such low molecular weights that they are actually highly viscous liquids. These grades are often combined with traditional nitrile polymers to reduce compound viscosity and improve the knitting and flow characteristics of the compound. Liquid grades maintain properties better than typical plasticizers after aging and also cannot be extracted since they are polymers and will crosslink into the polymer backbone. 
Suggested Grades

|---|---|---|---|---|---|
| 1312 | 28 | 20,000 - 30,000 | 0.96 | H | NS |
| 1312LV | 26 | 9,000 - 16,000 | 0.96 | H | NS |
Abrasion Resistant Compounds
Carboxylated nitrile (XNBR) is polymerized with acrylonitrile and butadiene but also incorporates a third, carboxyl-containing monomer into the polymer chain.? Compared with conventional NBR, XNBR has higher tensile strength, modulus, and hardness, but the key advantage is the significant improvement in abrasion resistance. Nipol NX775 offers enhanced scorch safety, allowing for a wider processing window and making it a viable option in difficult to mold parts.

Stator Applications
Nipol 3640S was specifically developed for stator applications in the oil field industry. Nipol 3640S is a low viscosity polymer to aid in processing and also offers improved scorch safety over traditional NBR grades. Nipol stator grades maximize in-service parameters and are optimized on the relationship between dynamic properties and pumping efficiency. Testing has also shown superior hot water adhesion compared to other available grades.
PVC Modification
ZEON makes many grades of acrylonitrile butadiene copolymers that can enhance the properties of flexible PVC compounds. These products are very easy to incorporate into PVC compounds due to the fact that they are available as a liquid or fine powder. Some of the benefits of introducing NBR as a modifier into a PVC compound include improved mechanical properties, impact resistance, chemical resistance, and low temperature flexibility.

Friction Materials
Nipol 1411 is a very fine pre-crosslinked and branched 38% ACN NBR powder. ?It is the industry standard in the modification of friction lining compounds. The uniform particle size of Nipol 1411 makes it a more effective modifier than other polymer-based options. While performance improvements are formulation dependent, typical benefits include improved pre-form green strength, increased brake effectiveness, fade resistance and compressibility, as well as other benefits like noise control, crack resistance and overall toughness.?
