(NH4PO3)n Intumescent Flame Retardant

CAS	68333-79-9
Molecular Formula	(NH4PO3)n n>1000
Solubility	TF-201:＜0.45%;TF-201S:＜0.7% (25℃, g/100ml)
Appearance	White powder
Application	1 . Intumescent coatings, on account of its low water solubility, TF-201 is particularly suitable as an ”acid donor” for intumescent coatings. Other essential components of intumescent systems include a binder, a carbon donor (e.g. pentaerythritol) and a blowing agent (e.g. melamine); 2 . Polyurethane foams, TF-201 is a suitable non-halogenated flame retardant for polyurethane foams. If the handling of TF-201 as a solid is not possible we recommend the dosage of the flame retardant by preparing a TF-201/polyol-suspension;
