Abstract
The subject of the application is a method for producing viscoelastic polyurethane foam, in which a polyol component containing a mixture of petrochemical polyols with repolyol and biopolyol, a surfactant, a catalyst, and water is mixed with an isocyanate component, then poured into a mold and seasoned. In addition to the petrochemical polyols, the polyol component contains from 10% to 30% by weight of repolyol and from 10% to 20% of a biopolyol with a hydroxyl value of 150 to 200 mgKOH / g.
