Polyether ether ketone (PEEK) Machining

Facts About Polyether ether ketone PEEK

PEEK will outperform any other plastic when it comes to heat and chemical resistance. This material is versatile enough to meet almost any use that requires performance. It comes at a higher price, but when performance is necessary, it is the go-to material. Peek is a semi-crystalline, high temperature resistant, engineering thermoplastic with exceptional chemical resistance, fatigue endurance and thermal stability.

PEEK offers excellent mechanical and electrical properties with a continuous working temperature of 480° F (250 degrees C) while being able to maintain mechanical sustainability out to 570° F (300 degrees C). This superior performance allows PEEK to function as an alternative to metal in many harsh environments at high temperatures in corrosive environments without significant degradation of properties.

PEEK is insoluble in all common solvents and as a semi-crystalline material has excellent resistance to a very wide range of organic and inorganic liquids. PEEK can be blended with other materials to expand its properties and application use.
