Low volatile liquid flame retardants, hydrolysis resistance and good thermal stability, suitable for polyurethane soft foam flame retardant. Solid flame retardant added to the liquid raw material easily precipitates, usually before foaming or foaming added. Solid flame retardant material viscosity will increase, reducing the activity of the product, adding inorganic flame retardant fillers on foam properties have some negative impact. The finer the more favorable retardant performance of the play, and mitigate the adverse effects of the physical properties of the foam. flame retardant
The solid fire retardant material viscosity increase, and the liquid flame retardant lower viscosity material, they can be used in combination, not only have a synergistic effect, and can adjust the viscosity of the reaction mass, to obtain a high flame-retardant product.
