**Physical Characteristics:**
This product is a high-performance expanded PTFE sealing tape designed for a wide range of industrial applications. It is manufactured using premium-grade pure PTFE dispersion resin, offering excellent chemical resistance, low friction, and superior sealing performance. The tape is flexible, compressible, and has strong anti-creep and cold flow properties, making it ideal for sealing even complex or damaged surfaces.
The material is easy to apply directly onto flange surfaces, minimizing waste and reducing installation time. It provides a secure seal without requiring frequent retightening, especially in heat exchangers or other critical systems. Its inert nature makes it suitable for use with most chemicals, including solvents, acids, and gases. It is also ideal for sealing large equipment, saving both time and cost during installation.
