Verfahren zur Herstellung von Formkörpern auf Basis von einem Stärkeprodukt, sowie eine pulverförmige Mischung zur Verwendung darin

The invention relates to a process for manufacturing mouldings, wherein 500-1500 parts by weight of starch or starch derivative, 0.5-50 parts by weight of xanthan gum, 5-250 parts by weight of a reactive siloxane, 25-300 parts by weight of an inert filler, and preferably also 0.5-50 parts by weight of a salt are mixed with water to obtain a homogeneous dough, and the dough is baked in a baking mould. The mouldings obtained are properly resistant to water and moisture and possess a great mechanical strength. Moreover, they can be easily composted or biologically decomposed, after which eventually only useful and innocuous residual materials are left. The invention also relates to a powdered mixture containing starch or starch derivative, xanthan gum, an inert filler, and preferably also a salt in the above-indicated weight amounts.
