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.

Fluoroplastic silicone vulcanizates

Re-processable thermoplastic elastomer composition comprising (A) a thermoplastic polyurethane polymer, and (B) a silicone elastomer, wherein the weight ratio of the silicone elastomer to the thermoplastic polyurethane polymer is from 5:95 to 85:15, are disclosed along with methods for making such compositions.
