The R.J. Marshall Company FSD479 is an antimony free proprietary inorganic blend flame retardant synergist for use with halogen based flame retardant polymer compounds where Zinc Hydroxy Stannate is used as the primary synergist. It allows the formulator to reduce the amount of the expensive Zinc Hydroxy Stannate while retaining flammability performance and hence provide an overall cost saving. This product is applicable to PVC, CPE, and a wide range of polymer systems where the flame retardant is bromine or chlorine based.
