Zinc Hydroxystannate

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
  • Polyester Resins
  • 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
