ROBATEC® PEEK natural

PEEK | Polyether ether ketone

Semi-crystalline thermoplast | High performance plastic

Characteristics: Outstanding dimensional stability, extremely flame-retardant, self-extinguishing, very low smoke emission in the event of a fire, minimal moisture absorption, high purity level, very good resistance to gamma and X-rays, good sliding behavior, high wear resistance, little distortion under mechanical loads, resistance to exceptionally strong impacts, outstanding strength and hardness over a wide temperature range, only moderate distortion despite high temperature and mechanical stress, good machinability, good deep-drawing characteristics, good adherence properties, good weldability, good electrical insulation properties, high thermostability, extremely high continuous operating temperature, low linear thermal expansion coefficient, food safe (FDA)

Good resistance to water and steam (outstanding hydrolysis resistance for unreinforced material), alcohol, esters, bases, oil, grease, fuels
No resistance to sulfuric acids, nitric acids, halogens, MEK at elevated temperatures

Typical applications: Parts exposed to high temperatures, mechanical stress, and conditions such as X-rays or gamma rays
e.g. electrical insulators and housings, wire and cable insulation, rotor arms, thrust washers and seals, shock absorbers, components for analysis equipment, components for dialysis machines, valve linings, impellers for pumps
