We have in store for our clients a wide range of Zinc Hydroxystannate. Zinc Hydroxystannate has excellent flame retardant and smoke suppression properties of ZHS. Further, this can be used in Flame Retardant Low Smoke (FRLS) & Halogen-Free Flame Retardant (HFFR).
Zinc Hydroxystannate is also known as ZHS.

Zinc Hydroxystannate (ZHS) can replace Molybdenum Trioxide in PVC FRLS cable compound
ZHS was developed initially for use on halogen containing polymer formulation, especially flexible PVC for wires and cables
Zinc Hydroxystannate (ZHS) can provide Oxygen Index as well as Smoke Suppressant properties
By adding Antimony Trioxide you get oxygen index but smoke increases, while by adding ZHS you get oxygen index as well as smoke suppressant properties
The excellent flame retardant and smoke suppression properties of ZHS have been demonstrated for the following materials:-
PVC ( Rigid and Flexible), FRLS CABLE compound
Alkyd Resin-Based Paints
Polychloroprene ( Neoprene)
Chlorosulphoned Polyethylene ( Hypalon )
Polyamide ( Nylon 6 and Nylon 66 )
Epoxy Resins and Ethylene-Vinyl Acetate Co-Polymer
EVA, HFFR cable compound
