Fyrol® 6

Fyrol®6 is designed for use as a reactive flame retardant in polyurethane foams. Fyrol®6 is a reactive phosphonate ester that is incorporated into the foam structure by reacting as a polyol. It can also be used to aid in the bonding process for flame lamination of fabric with flexible foams. Fyrol®6 can be used as a flame retardant for printed boards and printing wiring board applications.
