We manufacture and supply a wide and stock-guaranteed range of Expanded PTFE Gasketing (Tefcan®), suitable for virtually any industry, from the simplest to the most complex applications and environments.
The unique material properties of Expanded PTFE allows for a strong, flexible material resistant to virtually all chemicals/corrosive media and withstands extreme temperatures and pressures.
Designed for easy installation, saving cost and time, as well as reducing equipment maintenance and downtime through its long and effective service life.
Vulcan Seals Tefcan® is made of 100% pure PTFE, expanded via a unique process into a consistent, highly fibrillated structure. Upon compression, the fibrils lock together to form a strong, uniform material, impervious to gases and liquids.
It seals under extreme temperatures, pressures and against corrosive media, where conventional materials would break down. Even during application, the material is incredibly resistant to creep, relaxation and cold flow - issues which are often associated with other gasket materials, especially virgin or filled PTFE.
Operating throughout the pH range, resistant to thermal cycling, non-contaminating and therefore can be used in virtually any industry, sealing the simplest to the most difficult of gasket applications.
Gasket Temperature: -240ºC to +310ºC (-450ºF to +600ºF)
Internal Pressure: From full vacuum to 207 bar (3,000 psi)
Media pH Value: 0 to 14 (except for molten alkali metals and elemental fluorine)
Limits are for guidance only. Product performance is also dependent on other equipment material and operating conditions.
Universal Joint Sealant
Expanded PTFE in cord form with a self-adhesive backing strip for ease of installation. It is a superior and cost-effective alternative to standard gasket sheeting. Ideal for complex or large gaskets and for resealing damaged, worn or distorted flanges.
