POLYMERFORBINDELSE TIL TÆTNING TIL ANVENDELSE MED FEDT-INDEHOLDENDE FYLDSTOFMATERIALER

摘要

The invention relates to a polymer compound for a sealing insert for a container closure, in particular for fat-containing filling materials, which has a composition such that the migration of constituents of the compound into the filling material is reduced, characterized in that the Shore A hardness of the polymer compound is between 45 and 95 and in the compressive deformation test analogous to ASTM D395-97 Method B at 70 DEG C the polymer compound exhibits a compression set of 30-90%.
