EXTERIOR WFX POLYMERIC FLAME RETARDANT TREATED WOOD
First of all, it is important to know the nature of the method used in manufacturing of a wood cladding treated with a polymeric flame retardant in order to understand why it is superior to all other known alternatives.
The method uses an advanced heat-curing polymeric system based on water soluble organic polymer system applied to the timber by vacuum pressure followed by a high temperature curing process which promotes polymerization.
This process chemically converts the water-soluble chemicals to permanent covalent bonds with the wood constituents (i.e., lignin, hemicellulose and cellulose), which ensures a long lifespan of the achieved flame retardant properties of the wood.
