2.3kg Spool ABSpro - Flame Retardant is a professional, halogen free, self-extinguishing filament which is engineered to meet the UL 94 V-0 flammability standards, meaning that the vertical burning of the filament, or 3D printed object, stops within 10 seconds. The mixture used for our ABSpro - Flame Retardant Black compound contains a high percentage of PolyCarbonate, ABS and added halogen-free flame retardant modifiers. Even though the compound contains a high percentage of PolyCarbonate, the flame retardant modifiers allows the filament to be printed at relatively low temperatures. Unique features Self-extinguishing flammability properties Engineered to meet UL 94 V-0 standards * Excellent dimensional stability Superb interlayer adhesion Halogen free High gloss General printing guidelines * Nozzle size: ≥ 0.15mmLayer height: ≥ 0.1mmFlow rate: ± 100% Print temp: ± 240 - 260° C *Print speed: MediumRetraction: Yes ± 5mm Heat bed: ± 110 - 120° C *Fan speed: 0-25%Experience level: Expert *) Because of the relative high percentage of added PolyCarbonate, ABSpro - Flame Retardant has a tendency to warp and therefore it is recommended to use a temperature-controlled build chamber and to prepare your heat bed with DimaFix fixative spray when 3D printing large(r) scaled objects with ABSpro - Flame Retardant.
