Flamtard S+ (calcium stannate) flame retardant synergist is a non-zinc containing stannate that provides tin-based chemical functionality, making it ideal for applications where zinc ions are not permitted or desired. It is insoluble in water and thermally stable (no weight loss) up to 400 °C. At higher temperatures (400 °C - 600 °C) calcium and tin ions can be volatilised or liberated from their structure to exert catalytic activity.
