  • Patent number: 7718727
    Abstract: Fluoroplastics containing fluorocarbon resins and silicones are prepared by first mixing a fluorocarbon resin with a compatibilizer, then adding a curable organopolysiloxane with a radical initiator, and vulcanizing the organopolysiloxane in the mixture. The fluoroplastics can be processed by various techniques, such as extrusion, vacuum forming, injection molding, blow molding or compression molding, to fabricate plastic parts. The resulting fabricated parts can be re-processed (recycled) with little or no degradation of mechanical properties.
    Type: Grant
    Filed: May 7, 2009
    Date of Patent: May 18, 2010
    Assignee: Dow Corning Corporation

  • Patent number: 7345118
    Abstract: A method is disclosed for preparing an elastomeric base composition comprising: (I) mixing by an extrusion process (A) a fluorocarbon elastomer with (B) an optional compatibilizer, (C) an optional catalyst (D) a silicone base comprising a curable organopolysiloxane, (E), an optional crosslinking agent (F) a cure agent in an amount sufficient to cure said organopolysiloxane; and (II) dynamically vulcanizing the organopolysiloxane, wherein the weight ratio of fluorocarbon elastomer (A) to silicone base (B) in the elastomeric base composition ranges from 95:5 to 30:70. The cured rubber compositions obtained from the elastomeric base compositions herein have good fuel resistance properties.
