Zinc Hydroxystannate, often abbreviated as ZHS, is a flame retardant additive used to reduce the flammability of various materials. It belongs to the class of inorganic flame retardants and is particularly effective in improving the fire resistance of polymers and plastics. It works by releasing water vapor and other fire-inhibiting substances when exposed to heat or flames, which dilutes flammable gases and reduces the temperature during combustion.
