Key Features

• Temperature Resistance: Skived PTFE membranes can operate in a wide temperature range from -180°C to 260°C (-292°F to 500°F). Their outstanding thermal stability ensures they do not become brittle in cold temperatures and do not melt or deform under high heat.
• Chemical Resistance: Skived PTFE membranes are almost completely inert to most chemicals and solvents. This resistance makes them ideal for use in environments where chemical exposure is a concern, providing effective protection against corrosion.
• Weathering Resistance: These membranes are highly resistant to atmospheric aging. They can be exposed to outdoor conditions for extended periods without degradation of their surface or performance.
• Non-stick Properties: Due to PTFE's low surface tension, skived PTFE membranes exhibit excellent non-stick characteristics, making them ideal for applications where contamination or build-up of materials needs to be avoided.
• Electrical Insulation: With a high dielectric strength of up to 10 kV/mm, skived PTFE membranes provide exceptional electrical insulation properties. They are used widely in applications that require effective insulation against electrical currents.
• Lubrication and Low Friction: Skived PTFE membranes have a low friction coefficient (0.04 to 0.15), making them suitable for use in applications that require lubrication and smooth operation under sliding or load conditions.
• Biocompatibility: PTFE is physiologically inert, meaning it is non-toxic and safe for use in applications involving human contact, such as in medical devices or food processing.

 Applications

• Microwave and High-Frequency Circuit Boards: Due to their excellent dielectric properties, skived PTFE membranes are widely used as substrates for high-frequency microwave circuit boards, RF (radio frequency) coaxial cables, and other high-speed communication cables.
• Electrical Insulation: These membranes are ideal for use as dielectric materials in capacitors, special cables, wire insulation, and electrical instrument insulation in various frequency ranges, providing reliable performance in electrical applications.
• Sealing Materials: Skived PTFE membranes are used in sealing applications, such as sealing tapes, gaskets, and other sealing products, where high chemical resistance, flexibility, and durability are required to prevent leaks and contamination.
• Anti-stick and Lubrication: The non-stick and low-friction properties of skived PTFE membranes make them ideal for use in anti-stick coatings and lubrication applications. These membranes are used in industries such as manufacturing, automotive, and food processing.
• Medical and Biotechnological Applications: Due to their biocompatibility and inertness, skived PTFE membranes are widely used in medical devices, wound care products, and as filtration elements in biotechnological applications, ensuring no harmful reactions with biological tissues.
• Food Processing and Packaging: The non-toxic and heat-resistant properties of skived PTFE membranes make them suitable for use in food processing, packaging, and baking applications, ensuring hygiene and preventing material contamination.
• Filtration: Skived PTFE membranes are also used for filtration applications in a wide range of industries, from pharmaceuticals and food processing to water treatment and chemical production. Their microporous nature allows for high-efficiency filtration of liquids, gases, and aerosols.
