ABSTRACT:
Improved blowing agents for thermoplastic and thermoset polymers are disclosed which contain silicate based compounds containing from about 5 to about 40% water and which expand or intumesce when heated to at least about 5 times their initial volume, which blowing agents are highly effective, predictable, stable and microwave receptive, do not cause post-blow, and which also act as an initiator or accelerator for other organic blowing agents.
