Spectrum PET-G FR V0 – Halogen-Free Flame Retardant Filament | 1.75 mm | 0.75 kg
The PET-G that doesn't catch fire: self-extinguishing, halogen-free, UL 94 V0* certified.
Spectrum PET-G FR V0 is a flame retardant PET-G based, halogen-free filament, designed to meet the requirements of the flame retardancy classification UL 94 V0*. This means that vertical combustion of the filament or the printed part does not exceed 10 seconds before self-extinguishing. The chemical modifications made to the formula do not compromise printability: the material maintains the classic properties of PET-G — low shrinkage, ease of printing, and excellent dimensional stability.
*The filament is not certified by Underwriters Laboratories and does not have an official UL number.
Key Features
- Self-extinguishing according to UL 94 V0 standard — vertical combustion max 10 seconds
- Halogen-free — safe for sensitive and enclosed environment applications
- Excellent dimensional stability — no warping, no shrinkage
- Oxygen Index 35% — highly resistant to flame propagation
- Glow Wire Flammability Index 960°C (1mm and 2mm) according to IEC 60695-2-12
- Comparative Tracking Index 600 V — good surface electrical resistance
- Does not require enclosed chamber, dry box or hardened nozzle
Ideal Applications
PET-G FR V0 is the mandatory choice wherever fire resistance is a regulatory or safety requirement:
- Electronics and electrical panels — enclosures for printed circuit boards, terminal blocks, cable ducts
- Automotive — flame-resistant interior components
- Industry — machinery housings with fire protection specifications
- Electrical circuit protection — coatings and shields for components at risk of overheating
- Models and prototypes for environments with high safety requirements
