PTFE Sheets & Gaskets
Premium Chemical-Resistant Sealing Solutions for Industrial Applications
PTFE (Polytetrafluoroethylene) is one of the most versatile and reliable sealing materials available today—engineered for environments where chemical resistance, thermal stability, electrical insulation, and low surface friction are essential. Specialty Gaskets provides high-quality PTFE sheets and gaskets, including trusted brands such as Durlon 9000/9400, Gylon 3504/3545, and virgin-grade PTFE for demanding industrial, OEM, appliance, and HVAC applications across Canada.
Whether you need a chemically inert gasket that won’t degrade, a smooth low-friction material for sliding surfaces, or an FDA-compliant solution for sensitive processes, our PTFE product line is designed to meet strict performance requirements.

Why Choose PTFE for Sealing & Gasketing?
Outstanding Chemical Inertness: PTFE is highly resistant to nearly all industrial chemicals—including acids, bases, solvents, and aggressive media—making it ideal for demanding processing, chemical manufacturing, and corrosive environments.
Exceptionally Low Friction & Non-Stick Performance: PTFE’s ultra-low coefficient of friction supports moving equipment, dynamic sealing, and components that require smooth, non-adhesive surfaces.
Wide Temperature Range: Suitable for high and low extremes, PTFE performs consistently from –268°C to +260°C, depending on grade and formulation.
Superior Electrical Insulation: With exceptional dielectric properties, PTFE is widely used in electrical, electronic, and high-frequency applications.
Long-Term Stability & Durability: PTFE does not age, absorb moisture, or react with most substances—extending service life even in harsh operating conditions.
