Reactive PIN FR for rigid polyurethanes
ICL (pinfa member) has launched an innovative phosphorus PIN FR which reacts into rigid PIR and PUR insulation foams. These are widely used for sheathings and for wall and roof insulation (more than 70% of commercial roofs). Because the new PIN FR reacts into the foam, it is stable and durable, without migration, so offering sustainability benefits. It is compatible with existing foam processes, chemically binding into the foam during production. It is a low-viscosity liquid, soluble in most organic solvents, with high polymer compatibility and benefits as a processing aid by reducing viscosity. It can be a “drop in” replacement for the chlorinated additive TCPP in rigid PIR and PUR foam products and closed-cell spray foams.
