The Sealing Materials Division of China Pulp and Paper Research Institute was formerly known as the Composite Materials Research and Development Center. It was established in 2009 and is committed to the research and development, production, application research, market development and technical services of high-performance green fiber composite sealing materials. The product can completely replace similar imported products, breaking the monopoly of China's high-end green (asbestos-free papermaking) fiber sealing materials by imported products. It can be used for domestic gasoline engines, diesel engines, gearboxes, air compressors, refrigeration equipment, and small general-purpose Manufacturers of engines, motorcycle engines, water pumps, oil pumps, etc., in industries involving water, oil, gas and other media sealing, provide complete sealing technology solutions.

　　Strong R&D strength is a strong guarantee for high-quality products:

　　, led by Dr. Zhuang Jinfeng, a national special expert on fiber rubber composite materials, has been engaged in the research of sealing materials and sealing technology for a long time in a world-class company in the United States;

　　The R&D team members have professional backgrounds in different disciplines, including polymer chemistry, papermaking technology, papermaking equipment, materials science, rubber technology, mechanical engineering and printing engineering, etc.;

　　Relying on the strong technological innovation capabilities of the China Paper Academy, the China Paper Academy is the only national professional R&D institution in the paper industry, and has the "National Pulp and Paper Engineering Laboratory" approved by the National Development and Reform Commission;

　　Research projects have successively won the National Development and Reform Commission's special industrial structure adjustment project, the Ministry of Science and Technology "Twelfth Five-Year" National Science and Technology Support Program Project, the Foreign Experts Bureau's Introduction of Foreign Technology and Talent Project, the Ministry of Science and Technology Small and Medium-sized Enterprise Science and Technology Innovation Fund and China Light Industry Group Science and Technology Innovation Fund And other financial support.
