Low VOC Reactive Phosphorus Polyol PU Flame Retardant For Automotive Interiors

Tailored for emission‑sensitive polyurethane end‑goods, IFR‑OP560 is a non‑halogenated reactive phosphorus polyol serving as a cost‑competitive replacement for Clariant Exolit OP560. Unlike conventional additive‑type flame retardants that tend to escape from polymer matrices over service time, this liquid polyol participates in PU cross‑linking reactions and becomes part of the polymer backbone. Such chemical anchoring keeps flame‑retardant moieties locked inside the material, supporting compliance with rigorous automotive emission requirements such as low fogging and trace‑level volatile organics. It maintains stable fire‑retardant performance without sacrificing the intrinsic hand‑feel or physical attributes of PU foams and elastomers.
