microFlon® fawn
Microstructured PTFE gasket sheets with silicon dioxide (SiO2)
microFlon PTFE gasket sheets, filled with finely dispersed silicon dioxide, TA-Luft certified – FDA compliant
microFlon® fawn is the universal PTFE seal for applications in the chemical industry.
Finely dispersed silicate fillers give microFlon® fawn very good cold flow resistance and good relaxation properties, even at elevated temperatures.
Due to its very diffusion-tight and uniform structure, microFlon® fawn is the ideal seal for high demands on lowest emissions.
Even at low installation surface pressures, the gasket material offers reliable safety and the lowest leakage rates.
