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.
As a sealing material supplier certified by ISO 9001/14001, Ruichen Sealing has long-term cooperation with leading companies such as Sany Heavy Industry and Sinopec, and its products are exported to 30 countries including Europe, North America, and Southeast Asia. We provide rapid selection support, non-standard customization and technical guidance for all categories of sealing materials, and have more than 40 patented technologies.
