DuraPro PC FR V0 is a flame-retardant polycarbonate compound for demanding industrial applications that call for enhanced fire protection. In third-party laboratory testing, printed samples of 1.5, 2.0 and 2.8 mm met the criteria of UL 94 class V-0. FDM-printed samples of 1.5 to 3 mm reached hazard level HL3, the highest of the three levels, for requirement sets R22, R23 and R24 of EN 45545-2, the European standard for fire protection on railway vehicles, which makes the material particularly suitable for interior components in rail vehicles. It also offers a Vicat B softening temperature of 115 °C and strong electrical insulation, with a volume resistivity of 1E15 Ohm·m, for safety-critical electrical and electronic applications. Final certification of a printed part remains the customer’s responsibility and depends on the application, geometry and part design.
