Manufacturing Insight LLC EFR-3 Enhanced Fire Retardant Additive

Subcategory: Additive/Filler for Polymer

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.
