FOAMING MIXTURE FOR PRODUCING ELASTOMERICS SILICONE FOAM

摘要

The invention relates to novel blowing agent compositions (a) based on aqueous emulsions comprising organopolysiloxanes (1), emulsifiers (2), water (3) and thickeners (4) for the preparation of elastomeric silicone foams. The novel blowing agent compositions are used in compositions which can be cured to form elastomeric silicone foams and comprise blowing agent compositions (a), diorganopolysiloxanes (b), crosslinking agents (c) and optionally crosslinking catalysts (d) and optionally fillers (e). The preparation of elastomeric silicone foams by heat-curing is carried out by mixing blowing agent compositions (a), diorganopolysiloxanes (b), crosslinking agents (c) and optionally crosslinking catalysts (d) and optionally fillers (e) and optionally further substances with one another and curing the mixtures at temperatures in the range from 100 to 250 DEG C with simultaneous foaming to give the elastomeric silicone foams.
