TEFCAN Sheet Gasketing is manufactured from expanded PTFE drawn into a homogeneous sheet of uniform thickness. The material is 100% PTFE. Unlike conventional gasketing materials, there are no elastomeric binders or fillers to deteriorate under constant elevated temperature and pressure.
Pliable and conformable, this advanced gasketing material readily fills surface irregularities, and seals scored or uneven flanges, without much increase in necessary bolt load. The exceptional ability of this material to seal can be seen from the following material comparisons:-
TEFCAN REQUIRES LESS THAN ONE THIRD OF THE BOLT LOAD REQUIRED BY C.A.F. TO SEAL WHEN TESTED AT 30 PSI GAS ON A ROUGH SURFACE FINISH FLANGE.
Once installed, the expanded PTFE sheeting compresses to around 30% of its original thickness to leave a solid uniform gasket. Due to its unique, highly fibrillated structure which imports multi-directional, high tensile strength, the TEFCAN Sheeting is extremely resistant to creep, relaxation and cold flow (unlike standard PTFE).
TEFCAN Gasket Tape
Tape Information
TEFCAN Gasket Tape provides the same material and sealing benefits as TEFCAN Sheet Gasketing but in a continuous strip form. The flat gasket tape combines the advantages of TEFCAN Universal Joint Sealant and Sheet Gasketing to form cut full-face, or strip sheet, gaskets with minimal waste.
Typical Applications
By Industry:
TEFCAN Sealants are so versatile they are suitable for use in virtually any industry. From the most straightforward, non-hazardous application to the most complex and aggressive environment, TEFCAN Sealants will provide exceptional performance . Industries widely utilising TEFCAN Sealants include: Chemical Processing, Petrochemical, Pharmaceutical, Food and Drink, Offshore Oil and Gas, Automotive, Power, Marine and Mining.
