Embodiment 1
[0218] In a kneader operating at 150°C, in 100 parts of trimethylsiloxy End-blocked, viscosity 8×10 6 In the diorganopolysiloxane of mPa·s, firstly mix 50 parts, and the specific surface area produced in the gas phase by the pyrogenic method is 200m 2 / g of silica, then mixed with 1 part of trimethylsiloxy-terminated dimethylpolysiloxane with a viscosity of 96 mPa s, then mixed with 7 parts with one Si in each terminal unit Hydroxyl-bonded dimethylpolysiloxane with a viscosity of 40 mPa·s, and then remixed with 1 part of trimethylsiloxy-terminated dimethylpolysiloxane with a viscosity of 96 mPa·s, and mixed with 1% by weight specific surface area of at least about 100m 2 / g and the average particle size of the primary particles is 13nm alumina powder (with The trade name Alu C was purchased from Degussa AG, Germany).
[0219] The mixture can now be pelletized or used as a mixture with good sheet integrity.
[0220]The mixture has good sheet integrity. It is characteri...

[0223] This mixture is now mixed with 1.5% 2,4-dichlorodibenzoyl peroxide (50% paste in silicone oil) on a roller mill. The mixture has good sheet integ...
Embodiment 3
[0225] In a kneader operating at 150°C, in 100 parts of trimethylsiloxy End-blocked, viscosity 8×10 6 In the diorganopolysiloxane of mPa·s, firstly mix 50 parts, and the specific surface area produced in the gas phase by the pyrogenic method is 200m 2 / g of silica, then mixed with 1 part of trimethylsiloxy-terminated dimethylpolysiloxane with a viscosity of 96 mPa s, then mixed with 7 parts with one Si in each terminal unit Hydroxyl-bonded dimethylpolysiloxane with a viscosity of 40 mPa·s, and then remixed with 1 part of trimethylsiloxy-terminated dimethylpolysiloxane with a viscosity of 96 mPa·s, and mixed with 1% by weight specific surface area of at least about 100m 2 / g and the average particle size of the primary particles is 13nm alumina powder (with The trade name Alu C was purchased from Degussa AG, Germany).
[0226] This mixture is now mixed with 0.7% dicumyl peroxide (98% strength) on a roll crusher. For homogenization, the roll mill was cooled to 40°C.
