![]() Meanwhile, the reasons of different influence of these fillers were analyzed during microstructure changes of PEEK composites with SEM photographs. The influence of expanded graphite and nano particles TiO2 on mechanical properties of PEEK composites was also be studied here. However, the tensile modulus kept constant during the change of PTFE content. With the increasing of PTFE content, the tensile strength was increased at first and then decreased rapidly. If the weight percent of short fibers was more than 10%, this increasing tendency became slowly. The results showed, with increasing of the weight content of short fibers, the tensile performance (tensile strength and modulus) of PEEK composites was increased rapidly. The weight content of short fibers, PTFE and expanded graphite was varied from 0-15%, and of TiO2 was varied from 0-8%. Thicknesses: 5mm, 6mm, 8mm, 10mm, 12mm, 16mm, 20mm, 25mm, 25mm, 30mm, 35mm, 40mm, 45mm, & 50mm.The tensile properties of polyetheretherketone (PEEK) composites, which were reinforced with short fibers, such as short carbon fiber (SCF), short glass fiber (SGF), or filled with polytetrafluoroethylene (PTEF), expanded graphite and nano material TiO2 were examined and studied. All these materials are well scrutinized to ensure all the products and materials that are installed meet or even exceed the industry standards. Components subject to repeated cleaning and sterilisationĭiameters: 5mm, 6mm, 8mm, 10mm, 12mm, 15mm, 16mm, 18mm, 20mm, 22mm.Further, the material offers exemplary performance over a wide range of temperatures and extreme conditions. As a thermoplastic, it has a unique combination of exceptional thermal, mechanical, and chemical resistance. Bearing Grade PEEK has enhanced bearing and wear properties. Glass-Filled PEEK offers enhanced mechanical and thermal properties over those of basic PEEK, plus excellent resistance in harsh chemical environments and is electrically insulative. Cog wheels, pump vanes, fittings, plug connectors What is PEEK (Polyether Ether Ketone) PEEK is considered one of the best performing thermoplastics in the world. PEEK Properties and Material Options Virgin PEEK (unfilled) is naturally abrasion resistant.PEEK ® CF30: This 30% carbon fibre reinforced grade combines even better mechanical properties (higher E-modulus, mechanical strength and creep resistance) than PEEK ® GF30 with an optimum wear resistance.ĪPPLICATIONS OF OMEGA-PEEK ® PEEK SHEET AND ROD.PEEK ® GF30: 30% Glass filled – exhibits a very high heat distortion temperature of up to 315☌ with a continuous working temperature of 260☌ combined with high stiffness and stability.WEAKNESSES OF OMEGA-PEEK ® PEEK sheet and rod Excellent hydrolysis and chemical resistance.Excellent radiation resistance to 1100 M Rads.High temperature performance – it resists beyond 240☌ (the heat distortion temperature is 162☌).MAIN ADVANTAGES OF OMEGA-PEEK ® PEEK sheet and rod These features, added to its excellent sterilisability by means of steam, dry heat and gamma radiation, makes this grade very popular in medical, pharmaceutical and food processing industries. Polyetheretherketone (PEEK) is a new kind of thermo-plastic polymer material, which has a low density, high mechanical strength, good electrical insulation. ![]() ![]() OMEGA-PEEK ® complies with EU and the FDA regulations in regard of food contact. OMEGA-PEEK ® exhibits excellent chemical resistance, very good dielectric properties and a very good resistance to all kinds of radiation (even ultraviolet rays only lead to a slight discolouration) and has very little effect of is self-extinguishing properties according to UL94. The Polyaryletheretherketone (PEEK) materials are semi-crystalline, high purity polymers comprising of repeating monomers of two ether groups and a keytone group. OMEGA-PEEK ® can be used at very high temperatures (about +260☌) and it shows an extraordinary mechanical strength, toughness, hardness, flexural strength and torsional strength. OMEGA-PEEK ® Polyetheretherketone (PEEK) is semi-crystalline advanced material exhibits a unique combination of high mechanical properties, temperature resistance and excellent chemical resistance making it the most popular of the advanced plastic materials. ![]()
