PC ABS FR LS R22-R23 PC ABS flame retardant low smoke R22-R23 blends have been used for long time in railway applications, for its ease of processing, design freedom and optimal balance in material mechanical properties, fire safety and surface appearance.
After the introduction in 2013 of EN 45545-2, a new European fire protection standard for railway vehicles (replacing former country specific fire regulations for railway), the fire safety requirements were increased and existing material solutions could not pass this new defined tests anymore. For each application requirement set (R1 to R26), the new standard defines 3 different Hazard Levels (HL) and various specific fire tests based on the so called FIRST method, which set a requirement for Flame Spread, Ignitability, Rate or heat release, Smoke and Toxicity.
MCPP Netherlands introduced a complete new innovative polycarbonate-based filament grade that is capable to pass the Hazard Level (HL3) for the most stringent requirement set R22 and R23 on 3D printed parts. PC ABS FR LS R22-R23 is a strong and stiff material with excellent surface aesthetics. The material will not bloom under humid and hot conditions and is printable on FFF printers.
