  • Patent number: 11905413
    Abstract: The invention relates to a device assembly and methods useful for producing molded silicone rubber products from liquid silicone rubber compositions (“LSR”) via injection molding. The methods provide a flexible process to produce faster cured silicone rubber products from LSR and allow for use of low curing temperature in the molding cavities without drastically lowering cure speed of the LSR and the physical properties of the produced molded silicone rubber material, therefore allowing liquid silicone rubber overmolding on or over heat sensitive substrates. The device assembly of the invention allows a faster cycle and the use of precise dosing and mixing units thus creating a flexible process to produce cured silicone rubber products faster from liquid silicone rubber (LSR).

  • Patent number: 11884847
    Abstract: A curable silicone adhesive having improved elongation-at-break and adhesive properties to various substrates, in particular synthetic textiles used in the manufacture of air bags, to be used, for example, as a joint sealer. These silicone compositions provide excellent adhesive properties such as peel strength and cohesive failure when used to seal joints/seams between two pieces of textile fabric. Airbag fabrics using such novel addition curable adhesive silicone compositions are also provided.

  • Patent number: 11345817
    Abstract: A two-part curable liquid silicone rubber composition is provided in which the first liquid composition and the second liquid composition yield, upon mixing, a curable liquid silicone rubber composition which, when cured, yields a silicone elastomer having an elongation-at-break value of at least 800%. The silicone elastomers of the invention comprise at least one alkenyl group-containing organopolysiloxane having two silicon-bonded alkenyl groups per molecule, at least one diorganohydrogensiloxy-terminated polydiorganosiloxane, at least one organosilicon crosslinker containing at least 3 silicon-bonded hydrogen atoms per molecule, at least one addition reaction catalyst, and at least one filler. Also provided are silicone elastomers having an elongation-at-break value of at least 800% and withstand elongation without breaking. An article for a medical device comprising a cured product of the two-part curable liquid silicone rubber compositions or the silicone elastomers of the invention are also provided.
