Abstract
Disclosed is a two-component polyurethane system for rotational molding, which includes a polyol component including a high functionality polyol with a functionality of larger than 3.5, a bio-sourced polyol, a viscosity modifier, a chain extender in a content of from 10 wt. % to 20 wt. %, based on a total weight of the polyol component, an amine catalyst, and a rheological modifier; and a di- or polyisocyanate component. Also provided are an article produced from the two-component polyurethane system and a method of producing the same.
