Fiberon™ PETG-rCF08 is a 3D-printing FFF filament from Polymaker: a PETG matrix reinforced with 8 wt% recycled carbon fiber. The fibers nearly double the in-plane tensile modulus over neat PETG (3.7 GPa vs ~2 GPa) and improve surface finish, while the filament remains processable at conventional FFF temperatures (240–270 °C nozzle, 60–70 °C bed). Anisotropy is significant — through-thickness (Z) properties are 30–50 % lower than in-plane (X-Y) because of inter-layer bond limits. Glass transition is 70 °C and thermal decomposition begins at 432 °C. The filament is hygroscopic (store below 20 % RH) and abrasive; hardened-steel or ruby nozzles are recommended — brass nozzles wear out in roughly 9 hours of printing.

Regulatory Screening

Environmental

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.
