Flamtard S (zinc stannate) is an insoluble, non-hazardous, antimony-free flame retardant synergist, and is increasingly being used in green applications, particularly in the electronics industry. It is extremely effective in PVC systems for cable sheathing, epoxy resins for printed circuit boards, polyamides and surface coatings. Flamtard S is thermally stable up to 400 °C; at higher temperatures (400 °C - 600 °C) zinc and tin ions exert catalytic activity that inhibits the radical chain reaction causing the flame.
