Frequently asked questions
CF grades require slightly higher temperatures and pressures. Very abrasive → carbide tooling is mandatory. Almost isotropic shrinkage is very low. Electrical conductivity must be taken into account in the design of parts.
PEEK is difficult to recycle economically. Production scrap is carefully recovered and reground for mixing into filled grades. Chemical recycling remains in the research stage.
Certain PEEK grades are approved for food contact (FDA, EU Regulation 10/2011) and medical applications (USP Class VI, ISO 10993). They are used in high-temperature food processing equipment and sterilisable surgical instruments.
