Kunstschnee fuer Dekorationszwecke und Verfahren zu seiner Herstellung
Other Title
Artificial snow made from foamed plastic or natural materials e.g. expanded starch - is either biodegradable or recyclable and closely resembles natural snow for use in displays and visual arts being produced with sparkle but without electrostatic charge in correct size distribution.
Abstract
This artificial snow provides a decorative, realistic imitation of natural snow. It has free-flowing qualities with flake size and size distribution strongly resembling natural snow. The novel feature is use of foamed, high molecular weight organic materials to make it. Also claimed is a corresponding process in which the material is first foamed, then torn up. In this way the process either produces the required size and size distribution in the flakes, or they are subsequently classified with this objective. USE - To imitate snow for window displays and artistic purposes, including the film and television arts. ADVANTAGE - This snow improves on an earlier type which was neither readily biodegradable nor re-useable. The snow is improved in appearance by the thin layer of unexpanded material, which gives it sparkle. A variety of recyclable plastics can be used, or natural materials, especially starch, which are readily biodegradable. Starch is particularly easily cleaned away, being so luble in water. Lack of electrostatic charge in all varieties, assists manufacture in conventional equipment, including sieving; it also facilitates use.
