Abstract

Flame retardant compositions that are halogen-free or substantially halogen-free are disclosed. In certain examples, the compositions comprise a halogen-free or substantially halogen-free epoxide and one or more phosphorated compounds. In some examples, the phosphorated compound comprises an average particle size less than 10 microns. In other examples, the phosphorated compound provides a surface area of 78.5 μm2 to about 1965 μm2. Prepregs, laminates, molded articles and printed circuit boards using the compositions are also disclosed.
