Polymeric composite materials (PСM) on the basis of low-molecular siloxane rubber which are supposed to be used as impression materials in stomatology are developed. As fillers for creation of PСM were used: amorphous aerosil; vegetable aerosil, received from waste of a rice peel; diatomite. Researches concerned definition influence of content of filler on working hours of siloxane compositions and a complex of properties of the developed impression materials.

Polymer composite materials (PCМ) based on low molecular weight siloxane rubber SKTN-A have been developed, which are supposed to be used as osteoplastic materials in maxillofacial surgery. The following materials were used as fillers for the creation of PCM: bentonite, sepiolite, wollastanite. The effect of the type and content of filler on the curing process and the properties of the resulting compositions was investigated.

The development of new polymer composites is governed by the need to improve the quality of the products being produced by improving their physicomechanical and service properties.
