PEEK is a high performance material, known for its high resistance to creep, fatigue, impact and high energy radiation. It is also known for its high operating temperature and low density compared to metals.

About the specific characteristics of PEEK

PEEK is a rigid polymer with a low coefficient of friction and low moisture absorption. It derives its unique properties from the polymerization of ether bonds with polycondensation-type kinetics. This engineering plastic can withstand a constant temperature of 250°C, but its melting temperature is 340°C. PEEK also resists well to hydrolysis and to the long-term action of chemicals. In particular, it remains unaffected by attacks from organic solvents at room temperature. It also resists creep, even under high temperatures. It is also highly resistant to wear and abrasion.

Thanks to its many qualities, PEEK is very much in demand in environments subject to high mechanical stress. It is therefore very popular in the automotive, aerospace and semiconductor industries. In the aeronautics industry, it replaces heavier and therefore more energy-consuming metal components.

Its performance is also highly valued in the medical and electronics industries. This thermoplastic is available on the market under the following trade names: Grade 450 (Victrex®), Vestakeep® (Evonik), Kepstan® (Arkema), KETRONPEEK®, SUSTAPEEK® and TECAPEEK®.

DEMGY, your specialist in the transformation and machining of high performance plastics

DEMGY has been working for more than 80 years now in the processing of high performance plastics. We have the expertise and equipment to process PEEK, as well as many other engineering plastics: PCTFE, PTFE, PFA, PVDF, Polyimide, PEI, PES, PSU, ETFE, PES, PA, POM, PPS and PAI. We can transform these materials into tube, bar, plate... We can also machine them to produce prototypes or high performance parts in series.
