Manufacturing Insight EFR-1 Enhanced Fire Retardant Additive

EFR-1 is ideal for incorporation into thermoset coatings, foams and potting compounds as well as electronic laminates and other similar applications, primarily epoxies. When blended into an epoxy resin system, EFR-1 will react to heat and/or flame by foaming and forming a thick, high yield char barrier. The char barrier will extinguish fire and prevent further flame spread. Additionally, the char foam insulates and protects the coated substrate from heat and fire damage.EFR-1 is halogen-free, contains no metals, PDBEs, PBBs or other brominated compounds and does not evolve the highly toxic and corrosive gasses associated with many other fire retardants. EFR-1 is a RoHS/WEEE compliant material. EFR-1 functions at loading levels in the range of 10% - 20% by weight. Flame spread and smoke developed values (ASTM E-84) are typically 10/10 and under and are in compliance with UL 94V0, MSC.41(64) and FAR 25.853.
