A method is disclosed for preparing an elastomeric base composition comprising: (I) mixing (A) a fluorocarbon elastomer with (B) a compatibilizer, (C) an optional catalyst, (II) mixing the product of step (I) with (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 (III) 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.

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.

A mattress constructed with multiple foam layers joined together provides reclining support with pressure redistribution for heavy weight persons, particularly those weighing over 350 pounds. The mattress includes: a core layer having a substantially planar top surface and at least two spaced apart regions in a bottom surface from which foam material has been extracted to leave cavities separated by an interconnected network of foam walls, a top layer of viscoelastic foam with an air permeability above 60 ft/ft/min, and a bottom layer of stiffer supporting foam. The open cavities of the core layer are directed away from the body supporting top surface of the mattress.

Organosiloxane compositions curable to silicone elastomers having improved weep properties are described. The compositions include an alkenyl-containing polydiorganosiloxane, an organohydrogensiloxane, a platinum-group metal catalyst and a MQ-type resinous organosiloxane copolymer having at least one fluorine atom-containing group per molecule; and a silicone elastomer prepared from such composition. A method of minimizing the leakage of a hydrocarbon fluid from a container using the silicone elastomer is also described.
