PEKK (60/40)

Verifiedpolymer

PEKK (polyetheretherketone) 60/40 is a high-performance aromatic polyketone thermoplastic that combines excellent thermal stability with mechanical strength, making it suitable for demanding structural applications. It is widely used in aerospace, automotive, and industrial sectors where components must withstand elevated temperatures, chemical exposure, and mechanical loading without significant degradation. Engineers select PEKK over lower-performing thermoplastics (like PPS or PEEK alternatives) when thermal limits, dimensional stability, and long-term performance in harsh environments are critical design constraints.

Safety & Biocompatibility

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
