Flame retardant P430
Flame retardant P430
P430 is a phosphorus-containing polyhydroxy reactive flame retardant, mainly used for the production of polyurethane foam for flame composite. The foam sheet containing 2 to 4 parts of this product can not only be flame retarded when it is combined with textile fabrics flame composite, but also improve the adhesion between foam and fabric, making the foam layer hot-melt and re-curing. P430 is soluble in polybasic alcohol and most organic solvents and easily soluble in water.
