UTECFLON - 1 [eng.]

General Information

UTECFLON-1
is an unfilled (virginal) PTFE (Polytetrafluorethylene) compound. PTFE is the most chemically resistant thermoplastic polymer existing and has outstanding chemical resistance to almost all chemicals and solvents. It has the lowest coefficient of friction of any solid material, is resistant to weathering and water-absorbtion and can be used over a wide range of temperature. PTFE has no memory and is subject to creep (“cold-flow”) and shall not be used for dynamic applications in water. UTECFLON-1 is compliant with FDA regulations.
