At the present time the actual task in the development of compositions for profile molding products made of wood-polymer composites is the search for effective binding agents for the system wood filler - polymer. In this work, we investigated the influence of different types of silica as binding agents on the properties of wood-polymer composites based on polyvinyl chloride. Silica sols had different stabilizing media, pH values and silica content. Tests were carried out on film samples obtained by rolling. Both technological and operational properties of the studied composites were considered. It was found that the introduction of silica, regardless of their type, increases the tensile strength. At the same time composites modified with silica with higher SiO2 content (about 30%), have increased values of strength characteristics. It was also found that silica sols stabilized with sodium ions (Na+) do not lead to an increase in melt viscosity.
