Chemical Description

  • Acrylonitrile/Butadiene Copolymer, known as NBR, is a synthetic rubber with high resistance to oils, chemicals, and heat.
  • Formed through the copolymerization of acrylonitrile and butadiene, allowing for adjustable properties by changing the monomer ratio.
  • Customization capability makes NBR suitable for a broad range of applications across different industries.
  • In the automotive sector, it's used for fuel and oil hoses, seals, gaskets, and diaphragms due to its oil resistance.
  • Utilized in the oil and gas industry for O-rings, gaskets, and seals, offering durability in environments with crude oil, natural gases, and chemicals.
  • Essential in chemical manufacturing for protective gloves, aprons, and other personal protective equipment (PPE) thanks to its chemical resistance.
  • Applied in construction and building for window and door seals, waterproofing sheets, and roofing materials, resistant to weathering and chemicals.
  • Food-grade NBR is used in food processing applications requiring direct contact with food substances, meeting FDA safety standards.
  • Special NBR grades are used in medical devices for gloves, tubing, and non-latex disposable supplies, providing barrier protection and chemical resistance.
  • NBR's advantage lies in its tailoring capability, allowing the creation of materials with balanced flexibility, toughness, and resistance to oils, fuels, and chemicals.
  • Advances in recycling technologies and the development of bio-based acrylonitrile and butadiene enhance the environmental friendliness of NBR products.
  • Acrylonitrile/Butadiene Copolymer is valued for its versatility, durability, and resistance, offering high-performance solutions with environmental responsibility.
  • Exhibits superior resistance to aliphatic hydrocarbons, minimizing swelling and degradation in environments exposed to fuels and oils.
  • Features enhanced performance in extreme temperatures, maintaining elasticity and function in both high-heat and sub-zero conditions.
  • Provides excellent resistance to abrasion and wear, crucial for components in high-friction applications.
  • Demonstrates resilience against atmospheric conditions like ozone, sunlight, and air, extending the life of outdoor applications.
  • Can be formulated to achieve specific viscoelastic properties, optimizing energy absorption and damping characteristics for vibration control applications.
