Description

Nitrile Rubber CAS NO 9005-98-5 is a synthetic copolymer of acrylonitrile and butadiene, valued for its exceptional resistance to oils, fuels, and chemicals. This material is critical for applications demanding high-performance elastomeric seals and components that maintain integrity in harsh environments. It is a fundamental raw material for manufacturers in the automotive, aerospace, oil & gas, and industrial machinery sectors seeking reliable, durable sealing solutions.

Application

• Automotive Seals & Gaskets: O-rings, shaft seals, and gaskets for fuel systems, engines, and power steering due to excellent oil and fuel resistance.
• Industrial Hose & Belting: Production of hoses for fuel, oil, and chemical transfer, as well as conveyor belts used in oily conditions.
• Oil & Gas Industry Components: Downhole packers, blow-out preventer seals, and other equipment requiring resistance to petroleum-based fluids and gases.
• Rollers & Printers' Blankets: Used in printing and paper processing machinery for its solvent resistance and durability.
• Footwear & Apparel: Solvent-resistant soles for safety footwear and industrial gloves.
• Adhesives & Sealants: Formulation of high-strength, flexible adhesives and sealants for industrial assembly.
• Molded Goods: Diaphragms, grommets, and custom-molded parts for various mechanical assemblies.
