Description:
Nipol DN219, Lowest Mooney viscosity version among Nipol NBRs.

Nipol DN223, Bimodal polymer designed to give good green strength in soft compounds. Low molecular weight portion acts as polymeric plasticiser. Typical applications in low hardness roller compounds for business machines.

Nipol DN2835, Low mould fouling, fast curing and easy processing. Good balance of low temperature flex and solvent resistance.

Nipol DN2850 is a copolymer with medium oil resistance. Sufficient non-staining antioxidant is added during manufacture for normal storage conditions. Low mold fouling, fast curing and easy processing. Good balance of low-temperature flex and solvent resistance.

Nipol DN2880, High cure rate, high modulus, low mould fouling, good balance of oil resistance and low temperature properties.

Nipol DN302, Well balanced oil and low temperature resistance with good resilience.

Nipol DN302H is a copolymer of general purpose Nitrile Rubber with medium-low ACN content and high viscosity level. Recommended for all rubber applications where improved low temperature performance is required while maintaining good oil resistance. Nipol DN302H is supplied in the form of cream to amber colored bales.

Overview:
Nipol NBR elastomers offer a good balance of performance and cost-effectiveness for applications needing fluid resistance, moderate heat resistance, and durability. We offer the broadest portfolio of NBR elastomers of anyone in the industry.

The factor to consider when selecting the approriate Nipol grade is Mooney viscosity, a measure of approximate molecular weight of the polymer. A low Mooney viscosity can improve the processability of the compound. As Mooney viscosity increases, the ultimate physical properties and compression set are improved.

NIPOL NBR are recommended when oil or solvent resistance is needed for the proper functioning of rubber parts. To obtain a broad spectrum of hardnesses and other essential properties, Nipol elastomers can be blended to achieve optimal performance. Nipol elastomers are the best value for all but the most demanding oil, heat and chemical applications and are available in powder, crumb, liquid and bale forms. Nipol nitrile elastomers are especially suitable for thermoplastics and thermoset modification; they are also used as additives in coatings and adhesives.

KEY ATTRIBUTES
Heat Resistance to 125°C
ZEON offers a full line of 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 ACN Content
By varying the 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).

APPLICATIONS
Abrasion Resistance
Carboxylated nitrile rubber (XNBR) is a terpolymer. 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.

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. 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.

Water Resistance
Nipol 1030 series NBR polymers were developed for use in applications requiring long-term resistance to water exposure. Nipol 1030 series polymers have water soluble ash values below 0.1%.
