NBR stands for Nitrile Butadiene Rubber, which is a type of synthetic rubber commonly used in industries where resistance to oils, fuels, and chemicals is required. It is a copolymer that is composed of acrylonitrile and butadiene.
NBR is known for its excellent mechanical properties, including high tensile strength, elasticity, and abrasion resistance. It also possesses good resistance to heat, ozone, and weathering, making it suitable for both indoor and outdoor applications. Its most notable characteristic is its exceptional resistance to oils, fuels, and greases, even at high temperatures. This property makes NBR widely used in automotive components such as fuel hoses, gaskets, seals, and O-rings.
Due to its oil resistance property, NBR is also extensively utilized in industries like petroleum, aerospace, and oil and gas. It is resistant to many chemicals and is commonly used for manufacturing gloves, hoses, tubing, conveyor belts, and gaskets in various industrial applications.
NBR can be molded and extruded easily, allowing it to be fabricated into different shapes and sizes. It can also be blended with other materials to further enhance its properties. The material exhibits good compression set, which means it can withstand repeated deformation and still return to its original shape. Additionally, it has a wide temperature range, performing well between -30°C and 120°C (-22°F and 248°F).
Overall, NBR is a versatile synthetic rubber that combines excellent resistance to oils, fuels, and chemicals with mechanical resilience, making it a preferred material in various industries.
