We had used PEEK in the oil logging tools under the working condition of 170℃ plus 140mpa and the material was functioning well.

So PEEK is an ideal material fit for the extreme environment. As mentioned before, the glass transition temperature of PEEK is 150℃ and the long-term service temperature is 260℃. For some industries which the working condition is both high temperature and high pressure, like the oil and gas industry, which requests the material keep insulation, great mechanical strength under the extreme environment. If you use the PEEK natural in the medical industry, the material also shows hydrolysis resistance to steam, which is an ideal plastic for the medical industry.Īnother excellent property of PEEK is the insulation which is a core index for the oil logging technology. Meanwhile, for the chemical resistance, PEEK natural has the greatest chemical resistance among the PEEK family, only 98% concentrated sulfuric acid could dissolve PEEK natural and the plastic also shows different levels of resistance to different chemicals. PEEK Virgin mechanical properties (source: Ensinger) So if you use PEEK natural under the frictional working condition, please beware of the material loss due to abrasion. Relatively low modulus means PEEK natural is ‘softer’ and does not wear resistance compared to other PEEK modified materials. Although the PEEK natural has high toughness, the modulus of elasticity of the material is only 4200mpa which is the lowest of the plastic family. We can see the elongation at break is 15% and impact strength (Charpy) is n.b. Besides the great properties mentioned before, PEEK natural shows the highest toughness of the PEEK family. PEEK natural or the virgin form of PEEK is the most widely used PEEK plastic. The most common PEEK plastics are PEEK natural, glass, or carbon fiber modified and the PEEK PVX. What should be mainly emphasized is that the long-term service temperature is up to 260℃(500℉).

This type of plastic exhibits a series of great properties, such as excellent chemical resistance, great mechanical strength, good dimensional stability, and so on. Polyether-ether-ketone, which is known as PEEK, is a high-performance, semi-crystalline plastic.
