On November 10th, the reporter was informed that Lanzhou Petrochemical Company successfully trial-produced the carboxyl nitrile rubber product XNBR-3304, and the related technical achievements filled the domestic blank. According to the analysis of the personnel of the quality inspection department, all the indexes of the product have reached the standard of excellent products. This indicates that Lanzhou Petrochemical has made a new breakthrough in the development of new synthetic rubber materials.

In recent years, with the rapid development of China's automobile industry, the market demand for high-performance carboxyl nitrile rubber materials continues to increase. The production process of carboxyl nitrile rubber products is complex and the quality standard is high. The domestic demand for carboxyl nitrile rubber has long depended on imports. In this regard, Lanzhou Petrochemical Company, Petrochemical Research Institute and Northwest Chemical Sales Company strengthened the cooperation of "production, marketing and research", deeply analyzed the demand situation of rubber market, adhered to the principle of "high-end, customized and environmentally friendly", put forward new product development ideas, and formulated a comprehensive industrial trial production plan for XNBR-3304 carboxyl nitrile rubber. The plan covers 11 aspects, such as process indicators, operation cards and emergency plans for emergencies. Technicians and operators earnestly implement the plan to ensure the smooth trial production.

Based on the existing 35,000 tons/year NBR plant, Lanzhou Petrochemical Company optimized the production process and promoted the industrial trial production of XNBR-3304 carboxyl NBR. Technicians carefully patrol, carefully supervise the plate and operate accurately, and the fine style of "high strictness and meticulous" of Lanzhou Petrochemical runs through every operation step to ensure the success of the trial production of new materials industry.

Carboxyl nitrile rubber is mainly used to prepare rubber products and mechanical parts with high oil resistance and wear resistance, which has become a new bright spot for enterprises to improve their core competitiveness and enhance their core functions.
