Figure 4 Tough FR V0 Black meets UL94 V0 at 3 mm and FAR 25.853(a) at 2 mm, providing controlled flame behavior without dripping or sustained combustion. In addition, the material maintains mechanical strength while limiting flame spread under load. As a result, engineers specify this UL94 V0 flame-retardant resin for housings, enclosures, and structural components that require documented fire performance.
This flame-retardant 3D resin delivers a tensile strength of 38 MPa and 44.6% elongation at break. This combination supports impact resistance and controlled flexibility under load. These capabilities make the black FR photopolymer perform well in snap-fit features, clips, brackets, and protective covers. Its isotropic behavior also supports predictable tolerances across repeated production builds.
Figure 4 Tough FR V0 Black maintains mechanical strength, color, and surface quality under UV exposure. Validated testing supports up to eight years of indoor performance and one year outdoors. In addition, the material is resistant to oils, fuels, and common cleaning agents extends part life in automotive, aerospace, and industrial environments. This stability enables fire-safe, production-grade workflows without secondary coatings or post-treatments.
