Four-fluorine board

Teflon sheet, also known as iron fluoride sheet, is available in two types: molding and turning. Its products have a wide range of applications and boast excellent comprehensive properties: withstanding extreme temperatures (-192℃ to 260℃), corrosion resistance (to strong acids, alkalis, etc.), climate resistance, high insulation, high lubricity, non-stickiness, and non-toxicity. Commonly referred to as the "King of Plastics," the Chinese product names include Teflon, Teflon, Teflon, Tefulong, Tefulong, and Teflone, among others.

The structural formula is -[-CF2-CF2-]n-, featuring excellentChemical StabilityCorrosion Resistance (PTFE, also known as F4, is one of the most corrosion-resistant materials in the world today, and "Plastic King" is a common nickname for it. It is a highly corrosion-resistant plastic that is not affected by known acids, bases, salts, or oxidizers. Hence, it is called the "Plastic King." It can withstand all chemical substances except molten fluorine, and is widely used in applications requiring resistance to acids and bases, organic solvents, excellent sealing properties, high lubricity, non-stickiness, electrical insulation, and good aging resistance. It has exceptional temperature resistance, capable of long-term operation between +250℃ and -180℃. While PTFE itself is non-toxic to humans, the raw material ammonium perfluorooctanoate (PFOA) used in its production is considered potentially hazardous.CarcinogenicThe product operates within a temperature range of -20 to 250℃ (-4 to +482°F), allowing for rapid temperature changes or alternating hot and cold operations. The pressure range is from -0.1 to 6.4 MPa (full vacuum to 64 kgf/cm2). Its development has resolved numerous issues in China's chemical, petrochemical, and pharmaceutical industries. The sealing rings, gaskets, and垫片 are made from suspended polymerization PTFE board resin molding. Compared to other plastics, PTFE board exhibits excellent chemical resistance and is widely used as a sealing and filling material.
