PTFE special – shaped sealing gasket

Introduction to PTFE Special-shaped Gaskets Material Characteristics - High Chemical Stability: PTFE special-shaped gaskets are inert to most chemical substances and can resist the corrosion of strong acids, strong alkalis and various organic solvents. For example, in the chemical pipeline systems, they will not have chemical reactions even when in contact with concentrated sulfuric acid or sodium hydroxide solution, and can effectively prevent leakage. - Wide Temperature Resistance Range: Such gaskets can be used within a wide temperature range, usually able to withstand temperatures from -196 °C to 260 °C. In low-temperature environments, such as the sealing of liquid nitrogen storage equipment, they will not become brittle; in high-temperature environments, like the sealing of some high-temperature reactors, they will not soften or deform. - Low Friction Coefficient: The surface of PTFE special-shaped gaskets is very smooth with an extremely low friction coefficient, which makes them perform excellently in sealing situations where there is relative movement. For instance, in the sealing of some valves that need to be opened and closed frequently, they can reduce wear and prolong the service life of the valves. Shapes and Applications - Special-shaped Design: Their shapes are customized according to specific sealing requirements. They may be round, square, oval, or have complex shapes with special protrusions or grooves. This customization can meet the requirements of various irregular sealing surfaces and ensure the sealing effect. For example, at the interfaces of some containers or pipelines with special shapes, special-shaped gaskets can fit tightly to prevent the leakage of media. - Wide Applications: They are widely used in many industries such as chemical, pharmaceutical, food, and electronics industries. In pharmaceutical equipment, they can ensure aseptic sealing during the drug production process; in food processing equipment, they can meet hygiene standards and prevent food contamination.
