Bidirectional modified ptfe based gasketing materials.
The SICHEM® product range is our biaxially-oriented PTFE sheet solution, combining excellent chemical resistance with optimal sealing performance.
The SICHEM® product range is developed for processes ranging from cryogenic temperatures up to +260° C and is suitable across the entire range of aggressive media (ph 0 to 14). SICHEM® is the right solution to achieve the lowest creep value, and seal integrity when it is vital to achieve minimum leakage and conventional PTFE based materials are not suited.
Using a patented process, we produce materials that have special controlled microporosity and a close-cell structure. Products from the SICHEM® family achieve high compression and sealability at low bolt torque values. They are optimized for applications with irregular sealing surfaces, compromised load capacity, or replacement of envelope gaskets.
