Description

2-Propenenitrile, Polymer With 1,3-Butadiene And Diethenylbenzene is a high-performance synthetic rubber, specifically a nitrile butadiene rubber (NBR) crosslinked with divinylbenzene. This formulation is engineered to deliver superior oil, fuel, and chemical resistance alongside excellent mechanical properties. It is a critical material for manufacturers requiring durable, flexible components that perform reliably in demanding environments. Key industries that rely on this polymer include automotive, aerospace, oil & gas, and industrial machinery for seals, gaskets, hoses, and molded parts.

Application

• Automotive Seals and Gaskets: Used in fuel systems, engine oil seals, and O-rings due to its excellent resistance to hydrocarbons and wide temperature operating range.
• Oil & Gas Industry Components: Ideal for downhole tool packers, valve seals, and hoses that encounter crude oil, drilling fluids, and other aggressive media.
• Industrial Hose and Belting: Serves as a primary material for fuel, oil, and chemical transfer hoses, as well as conveyor belts in mining and material handling.
• Rollers and Printing Blankets: Employed in the printing and paper industries for its resilience, solvent resistance, and consistent performance.
• Molded Technical Parts: Fabricated into custom components like diaphragms, grommets, and washers for machinery and equipment.
• Adhesive and Sealant Formulations: Acts as a key polymer in solvent-based and latex adhesives requiring oil and plasticizer resistance.
• Footwear and Apparel: Used in oil-resistant soles, industrial gloves, and protective clothing.
• Cable Jacketing and Insulation: Provides protective sheathing for cables exposed to oils, fuels, and chemicals.

Quality Control

Our 2-Propenenitrile, Polymer With 1,3-Butadiene And Diethenylbenzene is manufactured under a strict quality management system. Each batch is tested against rigorous internal specifications to ensure consistent performance in key parameters such as acrylonitrile content, Mooney viscosity, crosslink density, and mechanical properties. We provide comprehensive Certificates of Analysis (COA) upon request, detailing the specific characteristics of your shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C / 59-77°F). Keep away from sources of heat, sparks, and open flame. For long-term storage, maintain under an inert atmosphere to prevent oxidation and maintain polymer integrity.
