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

Other Description of flame retardant agent
Flame Retardant are substances that can be chemically inserted into the polymer molecule or be physically blended in polymers after polymerization to suppress, reduce, delay or modify the propagation of a flame through a plastic materials. There are several classes of flame retardants; Halogenated Hydrocarbons (Chlorine and Bromine containing Compounds and reactive flame retardants), Inorganic flame retardants ( Boron Compounds, Antimony oxides, Aluminium Hydroxide, molybdenum Compounds, zinc and magnesium oxides ), Phosphorous containing Compounds (Organic Phosphate Esters, Phosphates, halogenated phosphorus Compounds and inorganic phosphorus containing salts).
