Expanded PTFE TAPE is a sealing agent that is made of 100-percent pure PTFE. The expansion process produces a microporous fibrous structure which gives the product its unique mechanical properties.
Expanded PTFE is a soft, compressible gasket material. It is a form-in-place gasket that conforms to almost any sealing surface. Upon compression, it forms a thin, hard ribbon that fills in surface irregularities and creates an extremely tight seal. It is capable of withstanding a wider range of pressures, temperatures and chemical environments than any other soft gasket.
– full chemical resistance like solid sintered PTFE
– resistance against acids and bases of pH 0 to 14
– UV-resistant
– no aging, unlimited shelf life
– nontoxic, biologically inert
– non flammable
1. Low density: Expanded PTFE tape has a low density, making it a lightweight material, easy to handle and use.
2. Excellent chemical resistance: expanded PTFE tape has excellent chemical corrosion resistance and can resist a variety of corrosive media, including acids, alkalis, solvents and so on.
3. Excellent high temperature resistance: the expanded PTFE belt can maintain stability in high temperature environment, and its melting point is 327℃, which can withstand high temperatures.
4. Excellent insulation performance: the expanded PTFE tape has good electrical insulation performance and can effectively isolate the current.
5. Excellent wear resistance: expanded PTFE tape has excellent wear resistance and can resist friction and wear.
6. Good flame retardancy: expanded PTFE tape has good flame retardancy and can resist the spread of flame
1. Sealing material: expanded PTFE tape is often used for sealing pipes and joints, which can effectively prevent medium leakage.
2. Insulation materials: expanded PTFE tape is often used in electronic and electrical equipment insulation materials, such as insulation sleeves, cable insulation, etc., can protect the safe operation of electrical equipment.
3. Paper machine accessories: expanded PTFE tape is often used to cover the surface of the drum of the paper machine, due to its excellent wear resistance and anti-viscosity, it can extend the service life of the equipment.
4. Petroleum and chemical industry: Expanded PTFE tape is often used to seal pipelines and valves in the petroleum and chemical industry, due to its chemical resistance and high temperature resistance, to ensure the safe operation of equipment.
5. Medical devices: Expanded PTFE tape is often used in seals and gaskets in medical devices, such as surgical instruments and medical equipment, due to its chemical resistance and good flame retardant performance, to ensure the safety of medical devices.
In summary, expanded PTFE tape is widely used in various applications in sealing materials, insulation materials, paper machine accessories, petrochemical industry and medical devices due to its low density, chemical resistance, high temperature resistance, excellent insulation properties, wear resistance and flame retardancy.temperature resistance, excellent insulation properties, wear resistance and flame retardant.
