Silicone compositions with improved heat stability

摘要

The subject matter of the invention are silicone compositions to form elastomers, which the constituents of dollars a (a) 20 to 99% by weight - at least two polyorganosiloxane containing alkenyl groups per molecule and having a viscosity at 25 deg c. of from 0,1 to 500000 paes, dollar a (b) 1 to 80 w -% not - reinforcing filler having a mean particle size of from 0,1 to 200 mu m and a specific surface area of 100 m · 2 · / g, dollars a (c) cross-linking component, which is selected from dollars a (c1) organic peroxide and dollars a (c2) at least two sih - functions per molecule containing organosilicon compound in combination with hydrosilylation catalyst and dollars a (d) nitrogen compound, which is selected from amino -, ammonium, -, and nitrogen-containing esterifying organosilicon compounds which contain.
