Zinc Hydroxystannate (ZHS) is a white powder, non toxic flame
retardant with low heat release rates, dual phase action,
combining flame retardancy and smoke suppression, has synergy
with inorganic fillers and unlimited pigment compatibility.
Applications: ZHS was developed
initially for use on halogen containing polymer formulation,
especially flexible PVC for wires and cables. The results
obtained were so impressive that its application in halogen-free
formulation has also been developed. The excellent
flame-retardant and smoke-suppression properties of ZHS have
been demonstrated for the following materials: PVC (rigid and
flexible), polyester resins, alkyd resin-based paints,
polychloroprene (Neoprene), chlorosulphonated polyethylene (Hypalon),
polyamides (Nylon 6 and Nylon 66), epoxy resins and
ethylene-vinyl acetate co-polymer.
