Polychlorotrifluoroethylene (PCTFE)

Polychlorotrifluoroethylene (PCTFE)Description:

PCTFE is made from chlorotrifluoroethylene by suspension-polymerization or by emulsion-polymerization with a redox-indicator or a peroxide as starting reagent. PCTFE is a semi-crystalline thermoplastic. This material can be process by extrusion or injection moulding in temperature range of 280-350°C. (however at 280°C decomposition of the material begins) The properties of PCTFE are similar to that of PTFE, however PCTFE is harder and less durable compared with PTFE. PCTFE offers a unique combination between physical and chemical properties (not flammable, chemical resistant, excellent electrical properties) which can not be found in any other fluoropolymer. PCTFE is applicable in a wide temperature range (-240°C - 204°C).
