What is PCTFE material?
PCTFE (polychlorotrifluoroethylene), commonly referred to as Kel-F® or Neoflon®, is a fluoropolymer material with outstanding strength, stiffness, and dimensional stability. PCTFE has excellent chemical resistance, radiation resistance, and flammability characteristics.
Is PCTFE the same as PTFE?
PCTFE is a homopolymer of chlorotrifluoroethylene (CTFE), whereas PTFE is a homopolymer of tetrafluoroethylene. PCTFE is a harder and stronger polymer, with better mechanical properties than PTFE. Though PCTFE has excellent chemical resistance, it is still less than that of PTFE.
What monomer is PCTFE made of?
Some monomers like ethylene are used to produce melt processible copolymers of TFE. CTFE is also homopolymerized to produce polychlorotrifluoroethylene (PCTFE) and a family of CTFE based resins. HFP and vinylidene fluoride are also copolymerized with CTFE to produce elastomers.
Who makes PCTFE?
Daikin Industries Ltd.
PCTFE was developed and manufactured by the 3M Company under the brand name of Kel-F®. In 1995, the 3M Company discontinued manufacturing the resin and sold the rights to Daikin Industries Ltd., who now produces the resin under the brand name Neoflon® PCTFE.
How is PCTFE made?
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.
What is the difference between PTFE and PEEK?
In a nutshell, applications requiring strength and low levels of deformation would usually employ PEEK, whereas those requiring resistance to voltage or chemicals utilize PTFE. PTFE also rates highly in that it is self-lubricating. This makes it a preferred choice in high wear applications.
Is PCTFE a thermoplastic?
Polychlorotrifluoroethylene (PCTFE) is a thermoplastic chlorofluoropolymer; some of its fluoropolymer cousins include: FEP, Kynar® PVDF, Teflon® PTFE and Halar® ECTFE. Fluoropolymers are known for their excellent chemical and hydro-resistance.
Is Teflon a PEEK?
PTFE filled PEEK is a material that exhibits extremely good sliding and wear properties. Ensinger manufactures this material under the trade name TECAPEEK TF10 blue, using Victrex® PEEK 450G polymer. This PEEK product is often used in the food industry due to its good mechanical, thermal and chemical properties.

What is PCTFE Peek coating?
VICTREX PEEK coatings are typically used to improve resistance to chemicals, corrosion, abrasion and wear when applied to metal substrates. Through melt processing PCTFE resin can be modified to give different mechanical and optical properties by controlling the crystalinity of the material.
What is the Energizer code for PTFE seals?
PTFE Seal Design Guide Parker Hannifin Corp. Packing Division Europe 4.5.2 Energizer material The FlexiSeal®energizer material is designated with a sin- gle code in the standard part number (table 4.27): XXX – M000000 – 00 – 000 – 0 Refer to tables 4.26 and 4.27 to select the spring energizer code for your seal type and application.
Can PTFE be sealed with pigments?
Not recommended for sealing applications involving steam above 120 °C. Colour additives It is possible to pigment PTFE by using inorganic col- our additives that withstand the sintering temperature of PTFE. Pigments do not significantly change the properties of PTFE. Combinations of pigments and other fillers are possible.
