PEEK 450G

Verifiedpolymer

PEEK 450G is a glass-filled polyetheretherketone (PEEK) composite that combines the high-performance thermoplastic base polymer with reinforcing fibers to enhance stiffness and dimensional stability while maintaining PEEK's inherent chemical and thermal resistance. It is widely used in aerospace, automotive, oil & gas, and medical device industries where components must withstand elevated temperatures, aggressive chemical exposure, or demanding mechanical loads in continuous-use environments. Engineers select glass-filled PEEK over unfilled PEEK or competing thermoset composites when they need the combination of excellent creep resistance, low moisture absorption, electrical properties, and the processing advantages of a thermoplastic that can be injection-molded or machined into complex geometries.

Regulatory Screening

Environmental

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.
