**Physical Characteristics:**
This product is a high-performance PTFE expanded gasket tape designed for a wide range of industrial sealing applications. Manufactured from premium-grade pure PTFE dispersion resin, it offers excellent chemical resistance, low friction, and superior sealing performance. The tape is flexible, compressible, and exhibits excellent creep resistance as well as anti-cold flow properties, making it ideal for use in challenging environments.
It can be easily applied directly to flange surfaces with minimal waste, reducing the need for precise cutting or adjustments. This makes it particularly suitable for sealing large equipment, heat exchangers, and complex or damaged flanges without requiring retightening after installation. Its conformable nature ensures a secure seal even on irregular or uneven surfaces.
**Key Features:**
- Low coefficient of friction
- Excellent chemical resistance (pH 0–14)
- High tensile strength
- Flexible and easy to apply
- Resists creep and cold flow
- Suitable for both gas and liquid applications
**Applications:**
Ideal for sealing in chemical processing, pharmaceuticals, food and beverage, and other industries where corrosion resistance and durability are essential. It is commonly used in reactors, steam turbines, pipelines, and various types of vessels that handle chemicals, solvents, gases, water, and oils.
