NBR Rubber Seals

NBR (Nitrile Butadiene Rubber), known as nitrile rubber, buna-n rubber, or buna rubber, is a synthetic rubber commonly used in various applications. It is an elastomer co-polymerized by acrylonitrile and butadiene. Seashore Rubber can manufacture NBR rubber seals in different shapes, sizes, and lengths according to customer specifications and requirements. Our nitrile rubber has the following features:

  • Exceptional oil and chemical resistance
  • Excellent flexibility and durability
  • Good resistance to grease, hydrocarbons, and diluted acids
  • Excellent abrasion, wear and tear resistance
  • Can withstand severe weather conditions
  • Highly flexible to easily converted into different shapes and sizes

Properties of NBR Rubber Seals

  • Excellent Oil And Chemical Resistance: When exposed to chemical solvents, solutions, or aggressive environments, the NBR rubber seals maintain their original properties.
  • High tensile strength and elasticity make the NBR seals resilient to withstand harsh weather conditions and external impacts.
  • Excellent Abrasion Resistance: This makes the NBR seals more durable to deal with wear and tear and last for longer service life.
  • Exceptional Sealing Properties: This provides the nitrile butadiene rubber with a tight seal to prevent water, air, and dust infiltration.

Applications of NBR Rubber Extrusion

Thanks to its superior oil and chemical resistance, the NBR seal is ideal for various applications and industries, including automotive, aerospace, medical, and footwear. The nitrile rubber seal is mainly used to manufacture oil-resistant rubber products, such as automobiles and aviation.

Automobile Industry

NBR rubber is widely used in the field of automobile manufacturing. Including automotive seals, oil seals, O-rings, pipes, hoses, suspension parts and tires, etc. Its resistance to oil and abrasion makes it ideal for automotive parts.

Industrial Seals

NBR rubber is widely used as a seal material in the industrial field. It is used to seal and isolate liquids, gases and chemicals. It plays an important role in various mechanical equipment, valves, piping systems, storage tanks and pumps.
