Nitrile Butadiene Rubber (NBR), a synthetic elastomer, owes its exceptional performance to a precisely controlled chemical composition. The core of NBR's versatility lies in the copolymerization of acrylonitrile and butadiene. This process, thoroughly understood by us at NINGBO INNO PHARMCHEM CO., LTD., allows for a tunable material that can be tailored to specific industrial needs. As a leading supplier in China, we provide Acrylonitrile Butadiene Rubber that embodies the pinnacle of material science.

The defining characteristic of NBR is its impressive NBR rubber chemical resistance. This is primarily attributed to the polar nitrile groups (CN) within the polymer chain. These groups repel non-polar substances like oils and fuels, preventing swelling and degradation. The percentage of acrylonitrile in the polymer dictates the degree of this resistance. A higher acrylonitrile content (typically 18-50%) enhances oil and fuel resistance significantly, making it a superior choice for automotive and industrial seals, hoses, and O-rings. This fundamental aspect of its Nitrile Butadiene Rubber properties is what sets it apart.

Beyond chemical resistance, NBR offers a robust mechanical profile. It boasts high tensile strength, excellent abrasion resistance, and good tear strength, making it suitable for applications requiring durability. While its flexibility is generally good, it can be influenced by the acrylonitrile content – higher content means less flexibility at low temperatures. This is a crucial consideration when evaluating Acrylonitrile Butadiene Rubber applications in diverse environmental conditions. Our role as a high-performance synthetic rubber supplier is to ensure you select the grade that best matches your technical requirements.
