Most pump components can be injection-molded as long as they do not require tight tolerances. PEEK can be injection-molded, compression- molded, or extruded into stock shapes, which are typically machined to final-part dimensions. Poly(oxy-1,4-phenyleneoxy-1,4-phenylenecarbonyl-1,4-phenylene)(PEEK) is a semi-crystalline polymer with good thermo-mechanical properties and high chemical resistance which can be used as engineering plastics. Phenates, as illustrated by the following reactions: Polyetherification occurs when fluorinated aromatic ketones react with Those used for polysulphones, namely polyetherification and polyacylation. Polyaryletherketones may be prepared by methods which are analogous to Sulfonated PEEK (up to 50-70 degree of sulfonation(DS)) can be used in the formation of proton exchange membranes(PEMs) for fuel cells based applications.

PEEK can be sulfonated and coated on nanofiltration(NF) membranes which can be used in the fabrication of antifouling based NF membranes. PolyetheretherketoneĬan be injection moulded and extruded on conventionalĮquipment and can be used to prepare glass-fibre and carbon-fibre composites.Īpplications include coatings for high performance wiring used in theĪeronautics and nuclear fields and advanced structural composites. The material is soluble in concentrated sulphuric acid. Resistant to all organic solvents although a few can cause environmental The polymerĪlso has excellent electrical insulation characteristics. Highest of current commercial melt-processable thermoplastics. It withstands long periods at 250☌ with little change in mechanical Polyetheretherketone is a strong rigid material with outstanding heat resistance.
