Title: Blowing agent and method for producing foamed polymers and related compositions

Abstract: A silicate-based blowing agent and method for producing foamed polymer; provides a blowing agent containing at least one metal silicate, boric acid or a salt thereof, a peroxy compound, a reaction initiator and, optionally, a desiccant. The blowing agent is prepared by mixing the ingredients at least one time and allowing the mixture to rest without mixing until a dry dilatent gel is formed. The blowing agent is useful for the production of foamed polymers, especially for the production of foamed rubber.
