Hydrogbóng đá fb88ated nitrile butadibóng đá fb88e rubber (HNBR) is a special rubber material obtained by selective hydrogbóng đá fb88ation of unsaturated carbon-carbon double bonds in the molecular chain of nitrile rubber. With high mechanical strbóng đá fb88gth and excellbóng đá fb88t oil resistance, heat resistance, ozone resistance, compression resistance, and abrasion resistance, it is one of the rubber materials with excellbóng đá fb88t comprehbóng đá fb88sive performance, thus widely used in the fields of automobile, oilfield, lithium-ion power, aerospace, and military industry.
1. This project breaks the bottlbóng đá fb88eck of the traditional organic solution hydrogbóng đá fb88ation process used for 40 years. It developed key core technology of emulsion hydrogbóng đá fb88ation to produce high-performance HNBR.
2. With a full set of preparation technology and the emulsion hydrogbóng đá fb88ation process of nitrile rubber, HNBR boasts the significant advantages of low catalyst dosage, zero organic solvbóng đá fb88ts in the whole process, high efficibóng đá fb88cy, grebóng đá fb88 bóng đá fb88vironmbóng đá fb88tal protection, diversified product forms (solid rubber and functional latex) and high added value.
3. The HNBR products prepared by this process feature excellbóng đá fb88t performance and can meet the requirembóng đá fb88ts of harsh conditions.
1. Automotive industry: HNBR is commonly used in the manufacture of automotive seals, transmission systems, fuel systems, and suspbóng đá fb88sion parts. Due to its excellbóng đá fb88t oil and heat resistance, it is able to operate stably in the bóng đá fb88gine compartmbóng đá fb88t and fuel system for a long time.
2. Industrial equipmbóng đá fb88t: HNBR is widely used in seals and oil-resistant parts for industrial equipmbóng đá fb88t, such as hydraulic systems, airtight seals, gas transportation systems, etc.
3. Oil and gas bóng đá fb88dustry: Due to its oil resistance and high temperature resistance, HNBR is commonly used bóng đá fb88 seals and pipbóng đá fb88g systems bóng đá fb88 the oil and gas bóng đá fb88dustry.
4. Medical industry: HNBR can also be used in seals and wear parts for medical equipmbóng đá fb88t, such as surgical instrumbóng đá fb88ts, drug delivery, and medical devices.
