PEEK IntroductionPEEK(Polyetheretherketone) is a special engineering plastic with excellent properties such as high temperature resistance, self-lubrication, easy cnc machining and high mechanical strength. It can be manufactured and machined into various mechanical parts, such as automotive gears, oil screens, shifting start disks. ;
PEEK Material Features
High temperature resistancePEEK has a high glass transition temperature (Tg = 143 ℃) and melting point (Tm = 334 ℃). Its thermal deformation temperature under load is up to 316 ℃, and its long-term use temperature is 260 ℃. Instantaneous The use temperature can reach 300 ℃. Polyetheretherketone
PEEK Machining PropertiesPEEK machining properties has rigidity and flexibility, especially the fatigue resistance under alternating stress is very outstanding, and can be comparable to alloy materials.
Self-lubricating propertyPEEK has excellent sliding characteristics, which is suitable for the occasions with strict requirements for low friction coefficient and wear resistance, especially the sliding grade PEEK modified with carbon fiber, graphite, and PTFE. superior.
Corrosion resistanceIn addition to concentrated sulfuric acid, PEEK is insoluble in any solvents and strong acids and alkalis, and is resistant to hydrolysis and has high chemical stability.
Flame retardancyPEEK has self-extinguishing property, even without any flame retardant, it can reach UL standard 94V-0.
