  • Silicone rubber composition having improved storage stability
    Patent number: 7385000
    Abstract: Silicone rubber compositions useful for high-voltage insulators, and which cure to give silicone rubbers having a low combustibility, are addition-crosslinkable or peroxide-crosslinkable silicone rubber compositions containing aluminum hydroxide as filler, with the uncrosslinked composition having a storage stability which is improved compared to the prior art and improved processing properties by including an acid, base, or a compound which liberates an acid or base upon heating. These improved properties are achieved both with surface-treated aluminum hydroxide and with untreated aluminum hydroxide.
    Type: Grant
    Filed: October 13, 2005
    Date of Patent: June 10, 2008
    Assignee: Wacker Chemie AG
    Inventors: Arvid Kuhn, Werner Guske, Stefan Dietl

  • Silicone rubbers with improved mold release properties
    Patent number: 5889109
    Abstract: The invention relates to polyorganosiloxane rubber compositions which vulcanize to elastomers under the influence of heat and compriseA) 100 parts by weight of organopolysiloxane,B) 10 to 200 parts by weight of filler,C) 0.1 to 10 parts by weight of crosslinking agent which forms free radicals andD) 0.05 to 10 parts by weight of aliphatic alcohol with C.sub.8 - to C.sub.30 -alkyl radicals.The aliphatic alcohol (D) acts as an internal mold release agent.

  • Silicone rubbers of improved green strength and low compression set
    Patent number: 5721300
    Abstract: Polyorganosiloxane rubber compositions which cure to elastomers under the influence of heat comprise 0.01 to 1 part by weight of ammonium, alkali metal or alkaline earth metal carbamate. The green strength of the rubber compositions is increased by the addition of carbamate. At the same time, the compression set of the vulcanized rubbers are reduced.
