Expanded PTFE tape with adhesive backing is a high-performance sealing material made from 100% virgin polytetrafluoroethylene (PTFE) combined with high-grade 3M acrylic pressure-sensitive adhesive. It offers the exceptional chemical resistance, temperature stability, and non-stick surface of PTFE, while the adhesive layer provides unmatched installation convenience. Designed for sealing and static grounding in demanding industrial environments, this tape ensures reliable performance across a wide range of applications.
Outstanding Chemical Resistance: Withstands almost all strong acids, alkalis, oxidizers, and organic solvents, ensuring long-term durability even in highly corrosive environments.
Non-Stick & Easy to Clean: Prevents media adhesion, maintaining clean and stable sealing performance.
Self-Lubricating Surface: Extremely low friction coefficient minimizes wear during installation and operation.
Superior Weather & Aging Resistance: Maintains performance stability under outdoor or long-term service conditions.
3M High-Performance Adhesive: Easy to apply—simply peel and stick. Strong initial and lasting adhesion reduces maintenance time by over 80% compared with traditional sealing materials.
Quick Installation, No Tools Required: The adhesive backing simplifies application—just peel and apply directly to the sealing surface. Perfect for on-site repairs and maintenance.
Unmatched Chemical Protection: Pure PTFE ensures maximum resistance to chemical attack, preventing leaks and corrosion in pipelines, valves, and pump systems.
Built-In Static Dissipation: Under bolt pressure, the expanded PTFE structure forms conductive pathways, safely discharging static electricity and preventing ignition hazards in flammable environments.
Wide Temperature Compatibility: Performs reliably under both cryogenic (-240°C) and high-temperature (+260°C) conditions without losing flexibility or sealing integrity.
Long-Lasting Seal: Exceptional anti-creep and anti-aging characteristics ensure stable sealing pressure and long service life.
Chemical & Petrochemical: Ideal for flanges, pumps, and valves in chemical transfer lines handling acids, solvents, and corrosive fluids.
Pharmaceutical & Biotech: Suitable for hygienic and corrosion-resistant sealing in purified water and cleanroom systems.
Electronics & Semiconductor: Provides contamination-free sealing for high-purity chemical delivery systems.
Food & Beverage: Withstands CIP/SIP cleaning cycles without affecting product safety.
Power & Energy: Used in flue gas desulfurization systems and fuel line sealing.
Flexible and compressible—adapts easily to irregular flange surfaces.
Uniform deformation under bolt torque ensures a tight and leak-free seal.
Available in custom widths and thicknesses to match application requirements.
Expanded PTFE adhesive tape delivers an ideal combination of PTFE’s chemical inertness and 3M adhesive’s ease of use. It provides exceptional sealing reliability, long-lasting performance, and safe static dissipation for a wide range of industries.
