Applications :
  • 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


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
