  • Patent number: 7902284
    Abstract: Organosilicon compositions which can be cured to produce elastomers, in particular elastomers suitable for use in the food industry, contain very fine particulate aluminum oxide powder in minor amount. Non-blocking sheets and pellets can be formed from the compositions, and later molded and cured.
    Type: Grant
    Filed: July 4, 2007
    Date of Patent: March 8, 2011
    Assignee: Wacker Chemie AG
    Inventor: Peter Jerschow

  • Patent number: 7563855
    Abstract: Flame-retardant compositions contain peroxidically crosslinking, addition-crosslinking or condensation-crosslinking silicone rubber and at least one rhodium compound or iridium compound or mixtures of the two. The compositions exhibit increased flame retardancy as compared to similar compositions containing platinum complexes, and especially when used in conjunction with the latter, produce stable ceramic layers upon combustion.

  • Publication number: 20080125528
    Abstract: Organopolysiloxane moldings are prepared from (A) compounds which have radicals having aliphatic carbon-carbon multiple bonds, (B) organopolysiloxanes having Si-bonded hydrogen atoms, and (D) a hydrosilylation catalyst, by a process involving first preparing an admixture of 100 parts by weight of (A) and (B) or (A) and (D), and then feeding, into the mixer of a plastics-processing machine, either from 0.3 to 5 parts by weight of (D), based on the catalyst formulation, into the mixture of (A) and (B), or from 0.3 to 5 parts by weight of (B) into the mixture of (A) and (D).

  • Patent number: 6518371
    Abstract: A polyorganosiloxane containing the units (HR2Si—O1/2) HM units, (Si—O4/2) Q units, (R1Si—O3/2) T units and (R2Si—O2/2) D units in a ratio of from 2:1:0:0 to 6:4:2:2, or (HR2Si—O1/2) HM units, (R1Si—O3/2) T units, (R2Si—O2/2) D units and (R2(R1O)Si—O1/2) in a ratio HM:T:D:alkoxyM of from 1:2:0:0 to 3:4:2:2 is described, where R are identical or different, non-halogenated or halogenated hydrocarbon radicals having from 1 to 18 carbon atoms per radical, or are OR1, where R1 is a monovalent, unsubstituted or substituted hydrocarbon radical having from 1 to 8 carbon atoms, and in each molecule there are at least 3 Si-bonded hydrogen atoms. The polyorganosiloxanes are particularly useful as crosslinking agents in addition curable elastomer formulations.
