Firemaster® 520

A higher reactivity flame retardant for rigid polyurethane and polyisocyanurate foam applications, Firemaster® 520 has been developed in close consultation with foam manufacturers who need to change their formulations to accommodate alternative blowing agents.

Features and Benefits

• Highly reactive proprietary bromine containing Diol

• Faster reaction rates, lower viscosity and improved compatibility in water and pentane-blown systems

• Move to non-HCFC 141b blowing agents has changed the performance requirements for flame retardancy in rigid polyurethane foams – this meets the new requirements

Key Applications

• Insulation
• Roofing

Key Polymers

• Rigid Polyurethane
• Unsaturated Polyester (UPE)
