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).

Carboxylated nitrile rubber (XNBR) is a terpolymer made from the polymerization of acrylonitrile and butadiene monomers with a third, carboxyl-containing monomer. Compared with conventional NBR, XNBR has higher tensile strength, modulus, and hardness, but the key performance advantage is the significant improvement in abrasion resistance. Nipol NX775 utilizes proprietary ZEON technology to offer enhanced scorch safety over other grades of XNBR, allowing for a wider processing window and making it a viable option in difficult to mold parts.

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. Zeon later introduced Nipol 4040S, building on the excellent performance of Nipol 3640S but offering improved fluid resistance. 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.

NBR and polyvinylchloride (PVC) are highly compatible materials that offer a great balance of properties when blended together properly. This mixing process, called fluxing, is critical in obtaining the best properties possible. Sivic grades of NBR/PVC are fully-fluxed polyblends, which simplify production by eliminating PVC powder handling, simplifying logistics, and freeing up mixing capacity without additional investment. Sivic grades of NBR/PVC are ozone resistant, have excellent physical properties, and are easy to process, making them well suited for use in lay-flat hoses, cable jackets, and printing rollers.

Nipol 1411 and Nipol 1411C are very fine pre-crosslinked and branched 38% ACN NBR powders that differ only by partitioning agent type. The uniform particle size of these grades makes them more effective modifiers 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.

DuoMod DP5045 and DuoMod DP5045F are pre-crosslinked, carboxyl-functional NBR powders that were developed as tougheners for epoxy resins used in high-performance composites. The unique surface morphology and ultra-fine particle size allows for excellent compatibility and optimum dispersion of the powder through the epoxy resin systems without the use of solvents. DuoMod powders will improve interlaminar tack more than other elastomeric or thermoplastic modifiers and users will note a significant increase in fracture toughness, even at low loadings.

|DuoMod 5045||-5||50||Crosslinked, carboxyl-functionalized|

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.

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 NBR grades have better property retention than traditional polymeric plasticizers as well as superior extraction resistance due to the fact that they will crosslink into the polymer matrix on vulcanization.

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.
