Product Description

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.


Description of Product

Application :


1. Aqueous solution is used for the retardant treatment .To prepare 15-25%P-N flame retardant, used solely or together with other materials in the flameproof treatment for textiles, papers, fibers and woods, etc. To apply by autoclave, immersion or by spray both ok. If special treatment, it can be used to prepare high-concentration flameproof liquid to 50% to meet the flameproof requirement of special production.


2. It also can be used as flame retardant in water based fire extinguisher and wood varnish.


3. It is also used as a high concentration of binary compound fertilizer, slow released fertilizer.
