Application

Nitrile butyl rubber (NBR) is a versatile synthetic rubber known for its oil resistance due to its ability to resist swelling in both mineral and vegetable oils. It finds extensive use in general-purpose applications that require oil resistance, such as shoe soles, kitchen mats, sink toppings, and printing rolls. The medium acrylonitrile content in NBR provides a balance, making it suitable for these types of applications. Additionally, NBR offers good heat aging resistance, low creep, good resilience, and low permanent set, making it a reliable material for various practical uses. While it has poor resistance to oxygenated solvents and strong oxidizing acids, its ability to be blended with different types of resins enhances its utility. This compatibility enables NBR to be used in adhesives with high strength, suitable for industrial applications such as shoe sole attaching and structural bonding in aircraft. Its unique properties make NBR an essential material across multiple industries, providing a cost-effective solution for products requiring durability and resistance to both oil and moderate temperatures.
