High temperature resistance: It has high glass transition temperature and melting point, its load heat deformation temperature is as high as 316℃, and its instantaneous use temperature can reach 300℃.
Mechanical properties: It has rigidity and flexibility, especially the fatigue resistance under alternating stress is very outstanding, which is comparable to alloy materials.
Self-lubrication: It has excellent sliding properties and is suitable for occasions where low friction coefficient and wear resistance are strictly required, especially PEEK modified with carbon fiber and graphite in a certain proportion has better self-lubricating properties.
Corrosion resistance: Except for concentrated sulfuric acid, PEEK is insoluble in any solvent and strong acid and alkali, and it is resistant to hydrolysis and has high chemical stability.
Flame retardancy: It is self-extinguishing, even without any flame retardant, it can reach the 94V-0 level of the UL standard.
Ease of processing: It has the characteristics of good high temperature fluidity and high thermal decomposition temperature. Various processing methods can be used: injection molding, extrusion molding, compression molding and melt spinning.
Peeling resistance: The peeling resistance is very good, so it can be made into a thinly coated wire or magnet wire, and can be used in harsh conditions.
Fatigue Resistance: The best fatigue resistance among all resins.
Radiation resistance: The ability to withstand high radiation is very strong, surpassing that of polystyrene, which has the best radiation resistance among general-purpose resins. It can be made into a high-performance product that can maintain a good insulating ability when the γ-irradiation dose reaches 1100Mrad.
Hydrolysis resistance: PEEK and its composite materials are not chemically affected by water and high-pressure water vapor, and products made of this material can maintain excellent properties when used continuously in high-temperature and high-pressure water.
Smoke: PEEK has the lowest smoke among plastics.
Insulation stability: has good electrical insulation properties and maintains it to a very high temperature range. Its dielectric loss is also small at high frequencies.
Stability: Has excellent dimensional stability properties, which is important for some applications. Changes in environmental conditions such as temperature and humidity have little effect on the size of PEEK parts, which can meet the requirements for use in working conditions with relatively high dimensional accuracy requirements.
