Five common characteristics of PEEK: Suzhou Newest Precision Technology Co., Ltd. Release time: 2018-03-17 Mechanical strength -- peek is a plastic that has both toughness and rigidity and achieves a balance. In particular, its excellent fatigue resistance to alternating stress is more outstanding among all plastics, comparable to aluminum alloy. High temperature characteristics - PEEK resin has a high glass transition temperature (143C) and melting point (334C), which is one of the reasons why it can be reliably used in applications with heat resistance requirements. The load thermal deformation temperature is up to 316C (30% GF or CF reinforced grade), and the continuous use temperature is 250C. Sliding properties PEEK has outstanding sliding properties, and is suitable for the use with strict requirements for low friction coefficient and wear resistance. In particular, the sliding grades of carbon fiber, graphite and polytetrafluoroethylene with 10% mixed modification or 30% CF reinforced grades are all grades with excellent sliding characteristics. Chemical resistance PEEK has excellent chemical resistance which is second only to fluorine resin. Only concentrated sulfuric acid and concentrated nitric acid can dissolve or destroy it in ordinary chemicals. Hydrolysis resistant PEEK and its composites are not affected by water and high-pressure water vapor. Products made of this material can be continuously used in high temperature and high pressure water and still maintain excellent properties. Because of the above special physical properties, it has been widely used in aerospace, electronic information, petrochemical, automotive, medical and precision machinery fields, in addition to the field of national defense and military industry.
