PTFE has been used as a seal in critical operations for close on 50 years. It is undoubtedly the material
of choice for applications that require totally reliable sealing in any environment, from household water systems to the most aggressive and hazardous chemicals. The properties that make PTFE ideally suited
for all sealing applications include:

• Its non-wetting non-stick surface is resistant to enzymatic and microbiological attack and does not enable fungal or bacterial growth
• Its chemically pure and inert state gives unmatched resistance to water, gases, solvents, acids, alkalis and other reactive media
• Its lack of leach-able additives ensures no effect whatsoever on process fluids
• Its resistance to cracking and embrittlement even after long-term use
• Its lubricity prevents the binding and sticking of pipes
• Its retention of these properties over a very wide temperature range, from about -240°C to + 260°C
