As a technology-based company that has been deeply involved in the sealing material field for 30 years, Ruichen Sealing focuses on the research and development and production of engineering plastic sealing materials, providing high-performance solutions for global industrial customers. Relying on ISO 9001-certified R&D laboratories and precision production lines, the company has mastered core technologies such as polytetrafluoroethylene (PTFE) modification and carbon fiber composites. Its products cover six major categories, including PTFE, polyoxymethylene (POM), and polyetheretherketone (PEEK). It serves 500+ industrial customers worldwide, with business scope covering more than 30 countries and regions.
Ruichen Sealing's engineering plastic sealing materials achieve multi-dimensional performance breakthroughs through innovative formulas and composite technologies: the PTFE series uses gradient filling technology, with compressive strength increased by 50%-300%, friction coefficient as low as 0.05, and chemical corrosion resistance covering strong acids and alkalis; RC-PEEK material can maintain 120MPa compressive strength in 250℃ hot water, suitable for high-temperature sterilization equipment; RC-UPE ultra-high molecular weight polyethylene still maintains 85% impact strength at -200℃ low temperature, and the wear life is 5 times that of PTFE. All materials have passed FDA, ISO 13485 and other certifications, and are widely used in food and medicine (PTFE-5), petrochemical (RC-PEEK), semiconductor (carbon fiber filled PTFE) and other fields, with precise adaptability and long-term stability, providing reliable sealing guarantee for extreme working conditions.
Ruichen Sealing has 40+ patented technologies, in-depth cooperation with Sinopec, FAW and other companies, and its products are exported to Germany, the United States, Southeast Asia and other markets.
