![]() ![]() Our backup rings are made of pure PTFE, filled PTFE or peek, depending on the application. PEEK is a semi-crystalline, show high stiffness and hardness, has an unique high tensile strength and fatiue strength, Resistant to high-engery radiation, high abrasion and wear resistant, good electrical insulator even at high voltages, and is characterised mainly by its very good mechanical properties and exceptional dimensional stability even continous operation at high temperatures of up to 250☌. Because the backup rings fit closely with the housing, they prevent the pressurized elastic seal from squeezing into the sealing gap. In static applications, elastic seals are preferably equipped with corresponding O-rings. As one of the most popular thermoplastics on the market, PEEK has a unique chemical structure that makes it incredibly strong and stable even under the harshest environments. They are installed in grooves together with elastic seals. Polyether ether ketone (PEEK) is an organic thermoplastic polymer. Peek backup rings are protective and supporting elements made of anti extrusion materials, usually with rectangular cross-section. and back up ring seal is typically used with O Rings to eliminate extrusion at high pressures. These represent only a small percentage of standard blends available.Back-up Ring/anti extrusion back up rings are a ring that holds an elastomeric seal to its outline shape and in its right place. These are mean values and can be altered by material source and process. Superior resistance to gamma and X-rays.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 ☏). The Young's modulus is 3.6 GPa and its tensile strength 90 to 100 MPa. 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☌.
