It has two subsidiaries, which are engaged in the research and development and production of high-performance elastomer sealing materials and engineering plastics for sealing.
Ruichen Sealing is a leading sealing material supplier in China, focusing on the research and development and production of all kinds of sealing materials such as polyurethane, rubber, engineering plastics and high-temperature resistant polymer materials. The brand focuses on independent research and development, and provides high-precision products such as RC-PU series polyurethane, RC-NBR nitrile rubber, modified PTFE composite materials, etc., covering the needs of hydraulic systems, chemical equipment, food and medicine and other industries.
Our products cover a wide range of sealing material categories. Among polyurethane sealing materials, conventional polyurethane (RC-PU) is resistant to high pressure and wear, and can be used to make U-rings and other sealing parts, and is used in media such as mineral oil; water-resistant polyurethane (RC-PU-H) is resistant to hydrolysis and is suitable for water-glycol media in metallurgy and other industries. In terms of rubber sealing materials, nitrile rubber (RC-NBR) is often used for O-rings, etc.; fluororubber (RC-FKM) is resistant to high temperature and corrosion. Among engineering plastic materials, pure tetrafluoroethylene (PTFE1) is resistant to chemical corrosion and is suitable for food and other industries; tetrafluoroethylene filled with different materials, such as PTFE-2, adds glass fiber and molybdenum disulfide to improve its compressive resistance and other properties. These rich sealing material products can meet the sealing needs of different industries and working conditions.
