Product Description


TPU Specific halogen-free flame retardant FR-1400

FR-1400 of Copolyforce is specially designed for TPU, with phosphorus, nitrogen elements as the main flame retardant elements of halogen-free flame retardant which works by the mechanism of condensed phase flame retardancy. It has the advantages of low additive amount and high flame retardant efficiency. Not subject to RoHS and REACH restrictions; the surface of the final parts is smooth, with strong precipitation resistance, good water resistance, and excellent resistance to migration, excellent electrical properties and low smoke non-toxic and other characteristics.

Process Condition


1)Because the initial decomposition temperature of FR-1400 in air is 321 ℃, the processing temperature of twin screw extruder can be adjusted higher in accordance with the actual need to enhance the dispersion and enhance the plasticization effect. Maintain vacuum of the twin screw extruder during the processing is also needed.

(2)When FR-1400 is used, please pay attention to proper use of stabilizer, coupling agent, and other phosphorus/nitrogen flame retardant APP, MC or MCA after mixing.
