What material is kel F?
Kel-F® (PolyChloroTriFluoroEthylene) is a fluorocarbon based polymer and is frequently abbreviated as PCTFE. PCTFE combines physical and mechanical properties, non-flammability, chemical resistance, near zero moisture absorption and excellent electrical properties not found in any other thermoplastic fluropolymer.
What is the monomer for the polymer Kel F?
7.5. Kel-F is a chlorofluoro-homopolymer formed from chlorotrifluoroethylene (CTFE) as the monomer, similar to Teflon or polytetrafluoroethene (PTFE) that is formed from tetrafluoroethylene as monomer.
What is Kel f used for?
PCTFE is often used for aerospace applications when chemical resistance, a broad operating temperature range, and low flammability are required. It is also extensively used for cryogenic valve applications. PCTFE FDA Compliant grades available.
What is PFA polymer?
Perfluoroalkoxy Polymer- Chemical Compound (PFA) PFA is a co-polymer product of PTFE. The co-monomer perfluoroalkyl vinyl ether interferes in the crystallisability and molecular weight to achieve good mechanical properties and melt processability without sacrificing thermal performance and chemical resistance.
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.
What monomer is PCTFE made of?
polychlorotrifluoroethylene (PCTFE), synthetic resin formed by the polymerization of chlorotrifluoroethylene.
Is PFA the same as Teflon?
One commonly known PFA formulation is Teflon PFA. PFA has very similar properties to PTFE, though the biggest difference between PTFE and PFA is that PFA is melt-processed. This is accomplished through conventional injection molding as well as screw extrusion techniques.
Is PFA a fluorocarbon?
Fluoropolymers share several unique properties which make them suitable for use in the automotive, aerospace, oil and gas and medical industries. PTFE, PFA and FEP are the most well-known and common fluoroplastics.
Does PEEK creep?
PEEK plastic is tough, strong, and rigid, with superior creep resistance, and is excellent for applications where thermal, chemical, and combustion properties are critical to performance.
Is PEEK a good thermal insulator?
Insulation. PEEK has excellent dielectric properties, which means wherever this material is used it will also provide insulation, mechanical, and physical protection.
What is the difference between PCTFE and 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 does PCTFE stand for?
Polychlorotrifluoroethylene (PCTFE or PTFCE) is a thermoplastic chlorofluoropolymer with the molecular formula (CF2CClF)n, where n is the number of monomer units in the polymer molecule.
What is Kel F material?
Home Materials KEL F. Kel-F® (PolyChloroTriFluoroEthylene) is a fluorocarbon based polymer and is frequently abbreviated as PCTFE. PCTFE combines physical and mechanical properties, non-flammability, chemical resistance, near zero moisture absorption and excellent electrical properties not found in any other thermoplastic fluropolymer.
What is Kel-F?
KEL-F® Characteristics KEL-F ® is a fluorocarbon-based polymer that is unique in the number of advantages it offers. This PolyChloroFluoroEthylene thermoplastic material can tolerate temperature extremes, is nonflammable, has good chemical resistance and near zero moisture absorption and has strong physical, mechanical and electrical properties.
What is Kel-F® resin?
Notes: Kel-F® is a registered tradename of 3M. In 1995, 3M discontinued manufacturing of Kel-F. Currently, all PCTFE resin is manufactured by Daikin under the tradename of Neoflon® or by Allied Signal under the tradename of Aclon®. Kel-F is still the most commonly used tradename used to describe PCTFE.
What is the electrical-insulation capability of Kel-F®?
Kel-F® maintains an outstanding electrical-insulating capability through thermal cycling and in high humidity environments.
