Abstract
Flame retardant polymer compositions comprise stannic oxide hydrate in combination with hydrated zinc borate and a halogen source which may be the polymer itself. The zinc borate comprises from 50 to 65%, by weight of the oxide-borate mixture. Polymers that incorporate these flame retarding compositions exhibit improved flame retardant characteristics together with effective color stability in the presence of heat.
