Abstract:
1. An addition-crosslinkable silicone composition, comprising (A) 100 parts by weight of polydiorganosiloxane(s) having at least 2 alkenyl groups per molecule, whose viscosity is from 2,000,000 to 50,000,000 mPas at 25° C., and having at least 0.15 mol% of alkenylsiloxane units, based on all of the siloxane units, (B) from 1 to 50 parts by weight of polydiorganosiloxane(s) having no alkenyl groups and whose viscosity is at least 5,000,000 mPas at 25° C., (C) at least one SiH-functional crosslinking agent, (D) at least one hydrosilylation catalyst, and (E) from 3 to 90 parts by weight of at least one filler whose BET specific surface area is at least 50 m
