Flamtard S

Flamtard S by William Blythe is a smoke suppressant and flame retardant synergist with co-flame retardants that inhibits the development of flames and smoke. It is designed for polymer processing at temperatures below 220°C. It also functions as a co-additive in phosphate flame retardant containing polymer formulations to optimize char formation. It is used in green, “antimony-free” applications, particularly in the electronics industry. It is thermally stable (no weight loss) at very high temperatures (>400°C). It is an environmentally friendly product. At higher temperatures (400-600°C), zinc and tin ions can be volatilized or liberated from their structure to exert catalytic activity. It is part of a family of n-type wide bandgap semiconductors with a high concentration of free electrons in the conduction band, thus leading to high optical transmissions in combination with electrical conductivity. Flamtard S is extremely effective in PVC systems for cable sheathing, epoxy resins for printed circuit boards and polyamides.
