Title
(EN) BLOCK COPOLYMER RELEASE SURFACE FOR PRESSURE SENSITIVE ADHESIVES
(FR) SURFACE ANTICOLLANTE CONSTITUEE D'UN COPOLYMERE BLOC POUR ADHESIFS AUTOCOLLANTS
Abstract
(EN)
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 a 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.
(FR)
L'invention concerne des surfaces anticollantes renfermant des mélanges copolymères blocs polymère-siloxane extrudés. Au moins un bloc du copolymère est un polymère compatible avec le matériau polymère en masse, tandis qu'un deuxième bloc est un polysiloxane. L'invention concerne également des surfaces anticollantes co-extrudées comprenant au moins deux couches polymères, dont une constituée d'un mélange copolymère bloc polymère-siloxane. Ces surfaces anticollantes servent de revêtements anti-adhérents pour étiquetttes et rubans autocollants.
