Hydrogenated nitrile butadiene rubber (HNBR) is a special rubber material obtained by selective hydrogenation of unsaturated carbon-carbon double bonds in the molecular chain of nitrile rubber. With high mechanical strength and excellent oil resistance, heat resistance, ozone resistance, compression resistance, and abrasion resistance, it is one of the rubber materials with excellent comprehensive performance, thus widely used in the fields of automobile, oilfield, lithium-ion power, aerospace, and military industry.
1. This project breaks the bottleneck of the traditional organic solution hydrogenation process used for 40 years. It developed key core technology of emulsion hydrogenation to produce high-performance HNBR.
2. With a full set of preparation technology and the emulsion hydrogenation process of nitrile rubber, HNBR boasts the significant advantages of low catalyst dosage, zero organic solvents in the whole process, high efficiency, green environmental protection, diversified product forms (solid rubber and functional latex) and high added value.
3. The HNBR products prepared by this process feature excellent performance and can meet the requirements of harsh conditions.
1. Automotive industry: HNBR is commonly used in the manufacture of automotive seals, transmission systems, fuel systems, and suspension parts. Due to its excellent oil and heat resistance, it is able to operate stably in the engine compartment and fuel system for a long time.
2. Industrial equipment: HNBR is widely used in seals and oil-resistant parts for industrial equipment, such as hydraulic systems, airtight seals, gas transportation systems, etc.
3. Oil and gas industry: Due to its oil resistance and high temperature resistance, HNBR is commonly used in seals and piping systems in the oil and gas industry.
4. Medical industry: HNBR can also be used in seals and wear parts for medical equipment, such as surgical instruments, drug delivery, and medical devices.
