Abstract

The invention relates to a modeling composition consisting of binder which is present as a plastisol and optionally further additives, wherein the plastisol is composed essentially of PVC and plasticizer and wherein the composition comprises at least one phthalate-free plasticizer.

Description

technical field [0001] The invention relates to oven-hardenable styling compositions and their use. Background technique [0002] Plastic, oven-hardenable compositions for shaping and molding objects are known in principle. [0003] Styling compositions are also to be understood as so-called clays or, in the case of polymer-containing compositions, polymer clays. [0004] Thus, plastic, hand-mouldable and heat-hardenable compositions are known from DE 25 15 757 C3. Such compositions mainly consist of polyvinyl chloride, fillers and plasticizers. The disadvantage of such compositions is that they harden only at very high temperatures, wherein the hardening process takes place slowly. For this reason, the fracture strength of such hardened compositions is insufficient. Furthermore, it is disadvantageous that such compositions contain up to 30% by weight of phthalate-containing plasticizers, which are suspected of having hormonal or reproductively damaging effects.
