  • PTFE fiber

    Our company's filament fibers have excellent temperature resistance, chemical stability, high tensile strength, low shrinkage, and superior abrasion resistance.

    Based on polytetrafluoroethylene filament fiber, it can be processed into various high-performance mesh fabrics, base fabrics, sewing threads and other products.

  • ePTFE membrane

    Our company's PTFE expanded polytetrafluoroethylene (PTFE) sheets are composed of 100% polytetrafluoroethylene, and their multi-directional tensile fiber structure gives them unique properties. Even under extreme working conditions, this material exhibits extremely low compressibility and creep. Furthermore, to adapt to different applications, we can provide product sizes according to customer requirements.

  • Medical materials

    PTFE dental floss is a safe, non-toxic, and chemically stable oral care product. Compared to other dental floss materials, PTFE is non-allergenic and less likely to cause allergies. Its smooth surface effectively reduces friction between the floss and gums, helping to prevent gingivitis and periodontitis, and reducing the risk of gum infection. Using PTFE dental floss effectively removes food debris and other debris from between teeth that a toothbrush cannot reach.

  • fabric

    The iTEX series of garment membranes features a biaxially oriented, three-dimensional fiber mesh structure with high porosity and excellent uniformity, resulting in high water pressure resistance and superior moisture permeability. Its functional fabric effectively achieves windproof, waterproof, and breathable properties without feeling stuffy. Furthermore, the iTEX series of garment membranes is Oeko-Tex certified and has passed PFOA & PFOS testing, making it a reliable choice.

  • Lefuron heat exchanger

    The company's main business includes the engineering design and EPC contracting of flue gas waste heat recovery systems, fluoroplastic tubular MGGH systems, flue gas condensate recovery systems, and fluoroplastic tubular GGH systems, as well as the research and development and manufacturing of related fluoroplastic energy-saving heat exchange equipment. The company has passed ISO9001 quality management system certification and safety standardization system certification.

Partnering with giants to build an internationally renowned brand

In its future development, the company will always adhere to the principle of “technology leadership and innovation-driven development,” and with the corporate culture of “morality and professional excellence,” wholeheartedly serve its customers, be a socially responsible enterprise, and sincerely contribute its modest efforts to China’s environmental protection cause.

Partnering with giants to build an internationally renowned brand

Shanghai Jinyou Fluorine Materials Co., Ltd. is an innovative enterprise in the fluorine materials industry, integrating R&D, production, and sales. It was one of the earliest domestic companies to successfully develop “membrane cracking method for long and short polytetrafluoroethylene fibers,” filling a domestic technological gap and breaking the international monopoly. Its independently developed long and short polytetrafluoroethylene fibers, PTFE base fabric, and high-elasticity, high-temperature resistant, and corrosion-resistant polytetrafluoroethylene sealing plates have won national awards such as “Key New Product” and “Shanghai High-tech Achievement Transformation Project.”
