PTFE washerAs a performance sealing element, it plays a crucial role in industrial sealing due to its material properties and application fields.

Chemical stability and corrosion resistance

• Chemical StabilityPTFE gaskets are one of the most corrosion-resistant materials in the world today, boasting high chemical stability and excellent resistance to chemical erosion. They can withstand strong acids, bases, and oxidizers, and even boil in aqua regia without change. Apart from melting sodium metal and liquid fluorine, PTFE gaskets exhibit inertness to most chemicals and organic solvents.

• Broad applicabilityDue to its excellent corrosion resistance, PTFE gaskets are widely used in the chemical and petroleum industries, solving many corrosion issues in these fields.

Physical Properties

• Low friction coefficientPTFE washers feature a low coefficient of friction, making them one of the lowest in solid materials. This helps reduce equipment wear and energy consumption.

• Non-adhesivenessPTFE gaskets have a low surface tension in solid materials, thus they do not adhere to any substances, which is particularly important in food processing industries as they do not contaminate the materials they come into contact with.

• FlexibilityDifferent PTFE washers come in various sizes and have varying flexibility. They can be cut and installed to suit your specific needs, offering convenience and efficiency.
