FIELD: chemistry.
SUBSTANCE: present invention relates to a gypsum panel comprising a first polymer additive and a second polymer additive distributed therein, where the first polymer additive is polyvinyl acetate, and the second polymer additive is starch, where gypsum panel contains glass fibres immersed into it in amount of 2–10 wt. % with respect to gypsum; where total amount of first and second polymer additives is more than 4 wt. % and less than 15 wt. % with respect to gypsum. In the gypsum board, the amount of the first polymer additive can be equal to or greater than the amount of the second polymer additive. Starch can be leaded.
EFFECT: technical result is high strength of panel, high fluidity of plaster suspensions and high resistance to hygroscopic expansion.
