Heat-, heat-sound-insulated cardboards are intended for thermal and sound isolation in plants, home appliances, and also as the closed isolation in multilayered designs of various branches of a national economy. A basis for manufacture of cardboards are basalt ultra-, superthin and thin staple fibers.

As binding for manufacture heat-insulated (HC) and heat- sound-proof (HSC) cardboards it is used bentonitic clay or polyvinylacetate dispersion. Cardboards are issued unhydrophobization and hydrophobization (index H).

Cardboards on clay связующем concern to a category not burned down, temperature of application + 700 °С at bilaterial heating and thermal protection surfaces up to + 1000 °С, on polyvinyl dispersed эмульсии - a category difficultly burned down, temperature of application + 500 °С. In waterproofing cardboards at temperature + 500 °С occurs destruction waterproofing liquids, however thus the material keeps the heat-sound-proof properties.

Manufacture without waste as waste of cardboards are a subject to repeated processing. Cardboards of marks HC-4, HCH-4, HSCК-6, АТМ-12 - flexible. Materials which are used for manufacturing cardboards, do not give in thermochemical destruction and harmful substances under action of physical factors are not allocated.
