PCTFE Sheet and PCTFE Plate

        PCTFE (polychlorotrifluoroethylene) sheet is a semi-crystalline fluoropolymer that bridges the performance gap between conventional engineering plastics and fully fluorinated polymers such as PTFE. The incorporation of a chlorine atom in place of fluorine in the polymer backbone reduces crystallinity and increases intermolecular forces, yielding a material that is measurably harder, stronger, and more dimensionally stable than PTFE while retaining excellent chemical resistance and an exceptionally broad service temperature range.

PCTFE is commonly referred to by its historical trade names Kel-F® and Neoflon.

We supply moulded & extruded PCTFE sheets with customizable thickness, width and length. Cut-to-size, CNC machining and custom fabrication services are available. We can provide standard grade and semiconductor high-purity grade options to match your specification and compliance requirements (ROHS, REACH, FDA, BAM available upon request).

Typical Applications

 The property profile of PCTFE sheet translates directly into service in some of the most demanding engineering environments:

• Semiconductor: high-purity gas delivery components, wafer carriers, wet process fixtures

• Cryogenic industry: LNG valve seats, cryogenic seals, gaskets for low-temperature fluid systems

• Chemical processing: sight glasses, corrosion-resistant liners, pump and valve components

• Aerospace & vacuum: vacuum chamber parts, low-outgassing structural spacers

• Pharmaceutical & medical: biocompatible sealing parts, sterilizable components

• Analytical instruments: transparent flow cells, sensor windows
