Material for O-Rings

  • Natural Rubber (NR): Derived from the bark of tropical trees, natural rubber finds a wide range of applications, including tires, airbags, flooring, gloves, and linings.
  • Polyisoprene (IR): This synthetic rubber possesses the same molecular structure as natural rubber, making it an excellent alternative.
  • Ethylene Propylene Diene (EPDM): Highly durable and dense, EPDM is preferred for products like gaskets, hoses, and seals due to its exceptional resistance to heat, oxidation, weather, and ozone.
  • Styrene Butadiene Rubber (SBR): More abrasion-resistant than natural rubber, SBR is commonly used in automobile and truck tires, showcasing resilience to heat, aging, and cracks.
  • Silicone (MQ): With remarkable heat and cold resistance (-80ºF to 450ºF), silicone rubber withstands prolonged exposure to sunlight, oxygen, ozone, moisture, and UV light, making it highly durable.
  • Butyl (IIR): Known for its impermeability to air and gases, butyl rubber is utilized in sealants for damp proofing, rubber roof repair, rubber membranes, gas masks, protective clothing, vial stoppers, explosives, chewing gum, and as an additive in lubricating oils and motor fuels.
  • Nitrile (NBR): Highly oil-resistant, NBR is extensively used in automotive seals, gaskets, and other products that come into contact with hot oils and fuels. It offers resilience and finds application in cleaning and examination gloves.
  • Polyurethane (PUR, TPU): Boasting excellent wear resistance, high tensile strength, and elasticity, polyurethane rubbers are chosen for applications where abrasion and oil/solvent resistance are essential.
  • Polychloroprene (CR): Commonly known as Neoprene®, it was one of the first oil-resistant synthetic rubbers. Though it has moderate resistance to petroleum-based oils and fuels, it remains a reliable general-purpose rubber with a balanced set of physical and chemical properties.
  • Thermoplastic Elastomers (TPE): Used in various industries such as automotive, construction, medical, food and beverage, electrical, appliance, and consumer electronics, TPE is versatile and serves multiple applications.
