    • A plastic film is provided that has release properties towards adhesives. The materials that produce the release properties are incorporated in the plastic layer and can be extruded with it. The materials responsible for producing the release properties are organo-silicone graft polymers or organo-silicone block copolymers obtained from mercapto-functionalized silicones, such as polydimethyl-siloxanes. The materials are produced by modifying SiH-containing polysiloxane with organic, polymerizable monomers of the type that can be produced with acrylates, such as methylmethacrylate, butylacrylate, styrene or vinyl acetate.
    • 提供了一种对粘合剂具有剥离性能的塑料膜。 产生释放性质的材料被结合到塑料层中并且可以与其挤出。 负责产生脱模性质的材料是由巯基官能化的硅氧烷如聚二甲基硅氧烷获得的有机 - 硅氧烷接枝聚合物或有机 - 硅氧烷嵌段共聚物。 该材料通过用可用丙烯酸酯如甲基丙烯酸甲酯,丙烯酸丁酯,苯乙烯或乙酸乙烯酯生产的类型的有机可聚合单体改性含SiH的聚硅氧烷来制备。

    • The invention relates to a method for producing a multilayer coextrudate, comprising a plastic layer that has release properties vis-vis adhesives, the release-property producing materials being disposed in the plastic layer. When the coextrudate is produced, a first web(support web I) is provided on the one side of which an adhesive layer is disposed, followed by the plastic layer having the release properties, which in turn is linked with a second web (support web II). The release layer does not show substantial migration with respect to the adhesive and the release effect does not substantially change afterwards, especially during storage.
    • 本发明涉及一种生产多层共挤出物的方法,其包括与粘合剂相比具有剥离性质的塑料层,该剥离性质生产材料设置在塑料层中。 当制造共挤出物时,在其一侧设置有粘合剂层的第一纤维网(支撑纤维网I),接着是具有剥离性质的塑料层,其又与第二纤维网(支撑纤维网 II)。 释放层相对于粘合剂不显示实质的迁移,并且释放效果以后基本上不会改变,特别是在储存期间。
