<p>Addition crosslinkable silicon mass (I) comprises: vinyl terminal polydiorganosiloxane (A) (100 parts by weight) with a viscosity of 5000-1000000 mPas; polydiorganosiloxane (B) (0.1-50 parts by weight) with a viscosity of 200-1000000 mPas; polydiorganosiloxane (C) (1-150 parts by weight) with a viscosity of 2000000 mPas; silicon hydride functional cross linkage material (D); hydrosilyl catalyst (E); and filler (F) (0-90 parts by weight) with a specific surface of at least 50 m 2>/g. Addition cross linkable silicon mass (I) comprises: vinyl terminal polydiorganosiloxane (A) (100 parts by weight) with a viscosity of 5000-1000000 mPas, where the amount of vinyl group in (A) is 0.1 mol.%; polydiorganosiloxane (B) (0.1-50 parts by weight) with a viscosity of 200-1000000 mPas, where the amount of vinyl group in (B) is 0.5-30 mol.%; polydiorganosiloxane (C) (1-150 parts by weight) with a viscosity of 2000000 mPas, where the amount of vinyl group in (C) is three per polymer chain; silicon hydride functional cross linkage material (D); hydrosilyl catalyst (E); and filler (F) (0-90 parts by weight) with a specific surface of at least 50 m 2>/g. Independent claims are included for: (1) the preparation of (I); and (2) a silicon elastomer produced by addition cross-linking of (I).</p> |
