8/3/2023 0 Comments Peek material price per kgIt has high resistance to biodegradation. It is soluble in concentrated sulfuric acid at room temperature, although dissolution can take a very long time unless the polymer is in a form with a high surface-area-to-volume ratio, such as a fine powder or thin film. It is attacked by halogens and strong Brønsted and Lewis acids, as well as some halogenated compounds and aliphatic hydrocarbons at high temperatures. It is highly resistant to thermal degradation, as well as to attack by both organic and aqueous environments. The thermal conductivity increases nearly linearly with temperature between room temperature and solidus temperature. 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 ☏). Its Young's modulus is 3.6 GPa and its tensile strength is 90 to 100 MPa. The processing conditions used to mould 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. ![]() The reaction is conducted around 300 ☌ in polar aprotic solvents - such as diphenyl sulfone. Typical is the reaction of 4,4'-difluorobenzophenone with the disodium salt of hydroquinone, which is generated in situ by deprotonation with sodium carbonate. PEEK polymers are obtained by step-growth polymerization by the di alkylation of bis phenolate salts. The polymer was first developed in November 1978, later being introduced to the market by Victrex PLC, then Imperial Chemical Industries (ICI) in the early 1980s. P e ek granules add carbon fiber lead the pellets became more good in friction coefficient,so the materials is usually use in electronic and cars parts.The usage is aimed to improve damage.Polyether ether ketone ( PEEK) is a colourless organic thermoplastic polymer in the polyaryletherketone (PAEK) family, used in engineering applications. PEEK resin and its composite materials are not affected by the chemical influence.Add long carbon fiber of peek pellets can improve the chemical resistance.The feature make the peek pellets can used for the field of aviation. PEEK resin is inherently flame retardant,it is not to add some materials to let peek pellets have flame retardant.And the feature of retardant is better use for some field where is high braking,high temperature and easy to cost fier.Ĭhemical resistance.
