The excellent mechanical performance of the PEEK makes the parts designed with less weight, durability and strength. Thus PEEK is an alternative solution for metals in severe conditions. The thermal performance of PEEK, as well as its abrasion and chemical resistance, ensures longer life and integrity of components in harsh environments.
The PEEK has good resistance to beta and X-rays as well as gamma rays (over 1000 billion without loss of mechanical properties). It is a strong candidate for medical programs due to its compatibility features (USP Class VI). This makes the PEEK ideal for use in many applications in the chemical, electrical and electronics, petrochemical, automotive, mechanical, medical, aerospace, semiconductor and food industries.
This material is very resistant to thermal attenuation as well as attack to organic and aquatic environments.
