A disadvantage is the high price, which limits its application to high value items. This means the main mechanical structure of the extruder can be made of the same material that is being extruded, provided that the PEEK insulator prevents heat from traveling beyond the intended melt zone. The processing conditions used to mold PEEK can influence the crystallinity, and hence the mechanical properties PEEK’s mechanical properties at elevated temperatures have led to it being used in at least two varieties of Reprap extruder as thermal insulation. These represent only a small percentage of standard blends available.Description PEEK ( Ketone ) Sheet PEEK is a semi crystalline thermoplastic with excellent mechanical and chemical resistance properties that are retained to high temperatures. These are mean values and can be altered by material source and process. Superior resistance to gamma and X-rays.PEEK maintains its excellent dimensional stability and good mechanical properties in a long time under. As a special polymer material, PEEK has high temperature resistance and good chemical resistance, excellent electrical properties, and flame retardant ( UL94 V-0). Moulded sheet up to 500mm x 500mm x 35mm (19.5” x 19.5” x 1.5”) Overview : PEEK (polyether ether ketone) is a semi-crystalline thermoplastic.Our Semi-finished capacity and capability All our materials are tested on site to International Standards so we can maintain a consistent quality product without impacting on lead times. We ensure the highest quality materials by mechanical property testing. In addition to this, we produce machine finished components for a range of industries including Aerospace, semi-conductor, Petrochem and Oil & Gas. We manufacture PEEK semi-finished products including rod, tube and sheet by compression moulding. It is extensively used in the aerospace, automotive, and chemical process industries. It is one of the few plastics compatible with ultra-high vacuum applications. It dissolves completely in concentrated sulfuric acid at room temperature.īecause of its robustness, PEEK is used to fabricate items used in demanding applications, including bearings, piston parts, pumps, HPLC columns, compressor plate valves, and cable insulation. It is attacked by halogens and strong acids as well as some halogenated compounds and aliphatic hydrocarbons at high temperatures. It is highly resistant to thermal degradation as well as attack by both organic and aqueous environments. Some grades have a useful operating temperature of up to 250 ☌ (482 ☏). PEEK has a glass transition temperature of around 143 ☌ (289 ☏) and melts around 343 ☌ (662 ☏). VICTREX PEEK polymer provides exceptional performance over a wide range of temperatures and extreme conditions. The Young's modulus is 3.6 GPa and its tensile strength 90 to 100 MPa. VICTREX PEEK (POLYETHER ETHER KETONE)LICENCED PEEK SUPPLIER, AVAILABLE IN A RANGE OF SIZES AND GRADES. The processing conditions used to mold PEEK can influence the crystallinity, and hence the mechanical properties. PEEK is a semicrystalline thermoplastic with excellent mechanical and chemical resistance properties that are retained to high temperatures. Polyether ether ketone (PEEK) is a colourless organic thermoplastic polymer in the polyaryletherketone (PAEK) family, used in engineering applications. Our range includes over 500 materials that offerĮxceptional characteristics enabling them to operate in Our company Fluorinoid® register, based on elastomer, PTFE and thermoplastic technologies includes over 500 materials that offer exceptional characteristics enabling them to operate in demanding environmental conditions at temperatures to over 300☌.
