rPETG EN13501-1 Flame Retardant
WINKLE 1.75 mm rPETG EN 13501-1 FR is a recycled PETG filament with a flame-retardant formulation for housings, signs, lighting, displays and prototypes where better documented fire behaviour is required than with conventional PETG. WINKLE markets it with a declared B-s1,d0 classification under EN 13501-1.
What B-s1,d0 means
- B: very limited contribution to fire within the EN 13501-1 classification system.
- s1: the declared smoke-production class.
- d0: the declared flaming droplets or particles class.
This concerns reaction to fire, not fire resistance of a building element, electrical insulation, absence of combustion or guaranteed fire prevention. It must not be described as “non-combustible” and does not replace final-product safety assessment.

The detailed technical sheet identifies these values with LFAM pellet material. They are formulation context, not guaranteed values for this spool or every FDM part. The filament-specific commercial document supports the printing settings above.
Compatibility and validation
Can be profiled on 1.75 mm FDM/FFF printers with a heated bed, including HTA3D HPRO, Creality Ender 3, Prusa MK3/MK4, Bambu Lab A1/P1/X1 and Voron, provided the machine and surface support PETG. WINKLE lists AMS; spool dimensions and the exact feeder still require checking.
- Store sealed with desiccant; the LFAM pellet drying cycle is not automatically transferred to the 1.75 mm filament.
- Tune temperature, flow and cooling using specimens representative of final thickness.
- Record batch, colour, profile, orientation and geometry when the part forms part of regulatory assessment.
- Do not mix materials, pigments or post-processes without reassessing fire behaviour.
- Request and review applicable documentation before specifying it in architecture, transport, electrical or public-space projects.
For parts without a reaction-to-fire requirement, standard WINKLE PETG is simpler. For recycled content without classification needs, see WINKLE PETG RE.
This is for you if
- You need an rPETG marketed with a declared B-s1,d0 classification.
- You will document and validate the part or assembly for its real application.
- You need white, black or transparent in a 1 kg spool.
This is not for you if
- You expect the filament purchase to certify the final product automatically.
- You require a non-combustible material, assembly fire resistance or certified electrical insulation.
- You cannot control batch, settings, geometry and assembly in a regulated application.
