Flamtard H
- CAS Number
- 12027-96-2
- EC Number
- 404-410-4
- Chemical Name
- Zinc Hydroxystannate
Flamtard H (zinc hydroxystannate) is an insoluble, non-hazardous, antimony-free flame retardant synergist that inhibits the development of flames and smoke in polymers. In halogen-containing polymers, the material has both condensed and vapor phase action during combustion. At 220 °C, the material releases 15w% of water, then at higher temperatures (400 °C - 600 °C) zinc and tin ions exert catalytic activity that inhibits the radical chain reaction causing the flame. In halogen-free polymers Flamtard H can increase the char consistency and strength.
