摘要:
The present invention relates to a halogen-free or substantially halogen-free flame-retardant composition comprising a blend of (i) at least one of each highly charring polymer (ii) at least one low volatility phosphate ester, and (iii) at least one compound which splits off a high volatility phosphorus-containing fragment. The invention also relates to a flame retarded thermoplastic composition wherein the flame retardant composition is blended with at least one thermoplastic resin (iv), preferable a polystyrene resin. The invention also relates to a process for manufacturing a flame retardant composition and a thermoplastic composition containing the same.
