Abstract: A composite material, comprising: (A) a particle comprising: (i) a core comprising one or more magnetic materials and (ii) a shell comprising silicon dioxide and (B) a polymer component selected from the group consisting of polyolefin homopolymers, polyolefin interpolymers, and combinations thereof, wherein the polymer component is free of free radical initiator is provided.

Abstract: The invention relates to a perforated film composition, comprising at least three layers, and wherein at least one layer is a inner layer with a softening and/or melting temperature, lower than the respective softening and/or melting temperatures of at least two outer layers, located at opposite surfaces of the inner layer, and where upon exposure to elevated temperature, the inner layer softens or melts to such an extent, that upon exposure to a compression force, a sufficient number of perforations seal in the inner layer, to impart an increased moisture barrier to the overall film composition. The invention also relates to a method of forming such a perforated film composition, packages prepared from the same, and a method of filling packages prepared from the perforated film composition.

Abstract: The invention describes a method and a device for processing by chip-cutting of workpieces. It is preferentially applied for the cross-cutting and chamfering of extruded plastics material tubes. A chip-raising or cutting tool may be fed forward radially with respect to a rotational displacement of the workpiece in the direction of a center of relative rotation. An undulant approach motion is superimposed over the feed motion of the tool. The undulant approach motions of two directly consecutive revolutions are displaced in phase. As a result chip cuttings of uniform and predetermined length are produced with consequent facility in removal and avoidance of interference with the cutting operation.
