Fyrol® FR2

Fyrol® FR-2 is a flame retardant additive commercially used in flexible and rigid polyurethane foams. Its superiority is demonstrated in excellent hydrolytic stability, low volatility, low fogging and processing characteristics, which enable its incorporation into foam formulations with little or no effect upon foam processing.

Fyrol® FR-2 is suitable for flexible polyurethane applications; the use of this flame retardant can easily achieve the California TB117 and automotive FMVSS302 flammability test. An adjunct flame retardant for HR-melamine foams, Fyrol® FR-2 has low fogging properties that meet the DIN75201 test for automotive foams. In addition, it can be used in epoxy resins, phenolics and unsaturated polyester resins.
