Key Features

• Low Relative Density: Manufactured from PTFE dispersion resin, low-density PTFE tapes have a special fibrous microporous structure that results in a lower relative density. This contributes to enhanced flexibility and conformability.
• Low Dielectric Loss: These tapes exhibit low dielectric loss, with minimal influence from temperature and signal frequency changes. Their stable dielectric constant ensures that they perform well in high-frequency applications.
• Excellent Temperature Resistance: Low-density PTFE tapes can withstand a wide temperature range, from -150°C to 260°C, maintaining stable performance even in extreme conditions.
• Superior Weather Resistance: They offer excellent outdoor durability, with resistance to mold, moisture, and salt fog, making them ideal for use in harsh environments.
• Other Characteristics: These tapes are also fire-resistant, have a low friction coefficient, are highly flexible, and possess strong chemical resistance.

 Applications

• Microwave Communications: Due to their excellent electrical and temperature properties, low-density PTFE tapes are widely used in microwave communications. They serve as high-quality insulation materials for RF coaxial cables, high-speed data communication cables, and phase-stable cables.
• Aerospace: The lightweight, corrosion-resistant, and high-temperature-resistant nature of low-density PTFE tapes makes them valuable in the aerospace industry. They are used to reduce structural weight, enhance fuel efficiency, and improve performance. These tapes are also employed as insulating layers for RF cables and microwave communication cables.
• Chemical Industry: Low-density PTFE tapes are used for sealing and insulating chemical pipelines, containers, and valves, offering reliable chemical resistance in corrosive environments.
• Electrical Insulation: These tapes are used for insulating electrical wires and cables, especially in applications requiring flexibility and chemical resistance.
• Other Specialized Applications: Low-density PTFE tapes are also utilized in various other fields, including automotive, medical devices, and electronic equipment manufacturing, where their unique properties are required for insulation, sealing, and protection against harsh conditions.
