  • Viscoelastic polyurethanes
    Patent number: 7022746
    Abstract: Viscoelastic foams and elastomers based on a reaction system comprising a monomeric polyisocyanate composition, a specified mixture of polyols, and a specified package of additives. The viscoelastic materials offer superior combinations of physical properties, including surprisingly low compression sets. Very soft viscoelastic foams and microcellular elastomers can be conveniently prepared from the reaction system without the necessity of using plasticizers. The reaction system can be processed into useful polymeric articles using a wide range of conventional polyurethane processing methods.
    Type: Grant
    Filed: May 27, 2004
    Date of Patent: April 4, 2006
    Assignee: Huntsman International LLC
