Hydrogenated nitrile rubber, also known as HNBR, draws attention for its standout chemical resistance and superior physical properties. The structure focuses on acrylonitrile and butadiene, with hydrogenation in the backbone. Modern engineering leans on this setup for extreme temperature and oil resistance, making it a first-choice material across automotive, oil and gas, and industrial manufacturing. The molecular formula speaks to its nitrile backbone, while hydrogenation lifts its ability to handle aggressive environments. HNBR density typically ranges from about 0.96–1.04 g/cm³. For trade reference, this material falls under HS Code 4002599000.
China supplies a huge share of global HNBR demand, offering access to a spectrum of supplier and manufacturer listings. Buyers who focus on direct-from-factory channels often see better price points, frequently reflected in cost competitiveness, especially in comparison to North America or European regions. On the supplier side, visitors will see resources that include up-to-date MSDS (Material Safety Data Sheets), TDS (Technical Data Sheets), and REACH, ISO9001, or SGS third-party certifications for quality and compliance. Chinese HNBR can be purchased with OEM, halal, and kosher certifications, which helps satisfy industry-specific requirements. Bulk pricing and quotations frequently ask for details such as CIF or FOB price, MOQ, intended use, and certification needs.
Anyone working with HNBR understands the importance of safe handling. The MSDS and SDS offer guidance on storage, PPE, and incident response. Manufacturers in China emphasize that while raw forms of HNBR are not acutely hazardous, proper ventilation and storage remain essential. Finished goods made from HNBR rarely pose a hazard to end users, but in production, limiting direct exposure to dust and vapors matters. Plant managers lean on liter-based inventory systems and solution mixing protocols; they frequently scrutinize purity, stable storage temperatures, and chemical compatibility as part of their best practices.
HNBR draws a following in high-value sectors looking for resistance to oil, fuels, ozone, and heat. Seals, gaskets, hoses, belts, and O-rings make up a huge portion of its application chart. OEM buyers hunt for products that display elongation at break above 150%, tensile strengths reaching 25MPa, and resistance to fuels over a long product lifecycle. The material’s structure and specification sheets present clarity on parameters like Mooney viscosity (ML1+4 @100°C), ACN content (typically 34–49%), and cross-linking systems. With these features, hydrogenated nitrile rubber thrives in both automotive air-conditioning and under-hood applications—high heat, plenty of oil, lots of wear cycles.
Procurement officers turn to China-based manufacturers for inquiries, seeking lower lead times, quote certainty, and favorable trade terms. Free samples support raw material evaluation before large purchase agreements. Policy shifts—like updates in REACH compliance or recent ISO and SGS audit requirements—regularly impact pricing and production lead times for both Chinese exporters and international buyers. Spot market news often covers price fluctuations based on feedstock costs, global demand surges, or regulatory changes.
Buyers prioritize suppliers who display consistent certification standards—REACH, ISO, halal, kosher—especially for export. CIF and FOB purchase terms anchor most international transactions, and volume determines final cost per metric ton or liter. Critical decision-makers look for traceable supply chains and specific warranty terms to hedge against shipping or quality problems. Purchasing in bulk secures pricing power, bolsters market position, and supports just-in-time delivery schedules.
