Zinc Borate can be used as a fire retardant in PVC, Polyolefins, Elastomers, Polyamides
and Epoxy resins.  In halogen containing systems  Zinc Borate is often used in
conjunction with antimony oxide.  In halogen free systems it is normally used with
aluminaa trihydrate, magnesium hydroxide or red phosphorus.  In some applications
Zinc Borate is used alone.  

We have expertise in the field of plastic formulations using Zinc Borate -- please ask
us if this chemical can be effectively used to solve your flame retardant problems.
