Their PTFE Teflon® * composition gives them excellent chemical inertia, temperature resistance from -200 to + 260°C , very good anti-adherence and no ageing.
They are soft and flexible. They are well suited to smooth or irregular surfaces, or when the assembly requires a weak tightening force (max. 150 N/mm² at 24°C ).
They resist pressures up to 210 bars and a pH of 0 to 14.
They are very useful in the chemical, food processing and pharmaceutical industries, and on metal, glass or plastic devices.
