Material Notes:
EFR-4 is ideal for incorporation into urethane resin systems, including coatings, foams and other similar applications.When blended into a resin system, EFR-4 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-4 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 retardants. EFR-4 is a RoHS/WEEE compliant material. EFR-4 functions at loading levels around 30% by weight but specific and individual product testing must be undertaken to qualify the formulation.
