Material Notes:
EFR-3 is ideal for incorporation into unreinforced thermoset resin systems, including coatings and foams, potting compounds as well as electronic laminates and other similar applications. EFR-3 has been proven especially successful in phenolic matrices, but also functions well in epoxy and urethane resin systems.When blended into a resin system, EFR-3 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 polymer substrate from heat and fire damage.EFR-3 is halogen-free, contains no metals, PBDEs, PBBs or other brominated compounds and does not evolve the highly toxic and corrosive gasses associated with many other fire retardant compounds. EFR-3 is a RoHS/WEEE compliant material. EFR-3 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.
