Flamtard H

Flamtard H 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. 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. It is an environmentally friendly product. Flamtard H has both a condensed phase and vapor phase action during the rapid degradation of polyvinyl chloride and polymer materials containing halogenated and antimony additives. In halogen-free flame retardant polymer materials it can act to increase the char consistency and strength.
