Fyrol® PCF

Fyrol® PCF is an additive flame retardant with very good hydrolytic stability used extensively in rigid and flexible polyurethane foams. It is soluble in most common organic solvents and exhibits outstanding polymer compatibility.

Fyrol® PCF is widely used as a flame retardant in roofing applications, and for laminate roofing and spray formulations. A class II ASTM E84 rating can be achieved with Fyrol® PCF, and it has superior hydrolytic stability for A or B components.

Fyrol®PCF can be used with unsaturated polyester resins and phenolics. It is an adjunct flame retardant for flexible-melamine foams, and meets the British BS5852 test. It may also be used in thermoset and thermoplastic materials as well as for textile finishes.
