Resumen de: WO2026017195A1

Molded articles made of established permanently plastic moldable masses are disadvantageously either not stable over several weeks or can no longer be remolded after several weeks. The aim of the invention is to overcome said disadvantages. This is achieved by means of a mass based on starch-based colloid, fat, and adjusting agents and auxiliary agents, a flocculation aid being added to the mass. The flocculation aid is capable of supporting the moisture content and enclosing impurities. For the first time, it is thus possible to obtain molded articles which last for months to years and can be remolded and which can be meaningfully used and reused for long periods of time as toys, modeling compounds for pastry designs, modeling compounds for molded building blocks, or also seals and reference bodies for lines.
