PTFE material (chemical name polytetrafluoroethylene, commonly known as Teflon) is a semi crystalline fluorinated plastic with many unique properties. It has very high thermal stability and chemical resistance, as well as a high melting point (-200 to+260 ℃, short-term up to 300 ℃). In addition, PTFE products have excellent sliding performance, excellent electrical resistivity, and non stick surface. However, compared to other plastics, this material has lower mechanical strength and higher shear density. PTFE plastic can be modified by adding glass fiber, carbon, or bronze to improve its mechanical properties. Due to its structural characteristics, polytetrafluoroethylene is usually molded by compression molding and then machined using cutting/processing tools.

Fluororubber (FKM) is a synthetic polymer elastomer with fluorine atoms on the carbon atoms of the main or side chains. Fluorine atoms have strong electronegativity, and their strong electron withdrawing ability can increase the C-C bond energy on polymer molecular chains, making the main valence bond more stable; At the same time, due to the slightly larger volume of fluorine atoms compared to hydrogen atoms, they can form a shielding effect on molecular chains and resist the erosion of external corrosive media. These structural features make them have excellent properties that cannot be compared to other rubbers, such as high temperature resistance, oil resistance, chemical resistance, good physical and mechanical properties, weather resistance, electrical insulation, and radiation resistance. They are mainly used to make rubber products that are resistant to high temperatures, oil resistance, and media
What is the difference between NSF H1 and 3H? What is NSF certification? NSF categorizes food grade lubricants into H1, H2, and H3, with H1 being suitable for "accidental contact" between lubricants and food or beverages. It can be used as a protective rust proof film, gasket, or sealing agent for food processing equipment, or as a lubricant for mechanical parts and equipment in areas where it may come into contact with food. Why should I use lubricants with H-1 certification? According to different exposure risks, equipment such as baking ovens, conveyors, and mixers are required to use H1
The four major processes of body manufacturing in the manufacturing of complete vehicles/MRO automobiles are stamping, welding, painting, and final assembly. Among them, the chains and bearings in the painting and final assembly lines work in humid or water vapor, water spray, corrosive, and high-temperature environments, and require shrinkage testing during drying. The selection of lubricants is the most important. The braking system is compatible with elastomers such as EPDM rubber, SBR rubber, and chloroprene rubber. Non corrosive plastic, wide temperature range, good corrosion resistance, low low-temperature torque resistance to brake fluid, rust and corrosion resistance, good wetting performance, and resistance to micro motion corrosion. Recommended lubrication process, recommended lubrication parts, recommended product environment and requirements, stamping workshop mold rust prevention
