Immersion Treatment Ammonium Polyphosphate Flame Retardant 68333-79-9

Ammonium Polyphosphate Flame for Wood Fireproof of Immersion Treatment

Chemical flame retardant methods are mainly chemical agents, that is, flame retardants to treat wood. The mechanism of flame retardant is to form a protective layer on the surface of the wood to isolate or form a supply of diluted oxygen.

TF-FR303 is mainly for wood/paper/textile liquid flame retardants. especially for wood immersion, which can reach " Class A". TF-FR303 is a water soluble grade, which is 100% water soluble and the solution is clear and neutral.
