PCTFE (polychlorotrifluoroethylene)
The addition of a chlorine atom, is partly responsible for a
lower melt index.
As a result, PCTFE can be used for extruding, injection
molding and hot pressing. It contributes to the transparency
of the material as well, the exceptional resistance to creep,
and the stiffness of the polymer.
Material Properties
• Especially suitable for cryogenic applications
• Excellent resistance to creep
• Dimensionally stable over a wide temperature range
• Extremely low gas permeability
• FDA approval
• Transparent and coloured compounds
• Working temperature from -240°C to +180˚C
Possibilities
• PCTFE rod
• PCTFE pipe
• PCTFE sheet/plate
• PCTFE film/foil
etc.
Technical information
PCTFE is widely used in Aerospace (seals), Semi-conductor, Oil&Gas/Petrochemical and
Machinery&Equipment Industry. Polyfluor guarantees the highest quality PCTFE with Zero Time Strength
ASTM D1430 and mechanical properties according to ASTM D638.
