Block copolymer release surface for pressure sensitive adhesives |
摘要 |
Release surfaces comprising extruded polymer-siloxane block copolymer mixtures are provided. At least one block of the copolymer is a polymer compatible with the bulk polymeric material, while a second block is polysiloxane. Coextruded release surfaces comprising two or more polymeric layers, including one layer of a polymer-siloxane block copolymer mixture, are provided. The release surfaces serve as release liners for pressure sensitive adhesive labels and tapes.
