Joseph M. Sutej has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Foam-forming mixtures with decreased decomposition of hydrohalocarbon blowing agents
    Patent number: 5693686
    Abstract: A polyisocyanate having an acid value of at least 0.01% HCl is used to produce polyisocyanate, polyisocyanurate and polyurethane urea foams with an HCFC blowing agent. The use of such a polyisocyanate is advantageous because the polyisocyanate does not cause significant decomposition of the HCFC blowing agent.

  • Low thermal conductivity foam
    Patent number: 5397808
    Abstract: The present invention is directed to the discovery that a specific combination of HCFC-141b, certain perfluorinated compounds and carbon black significantly improve the insulating capacity of isocyanate-based foams when compared to foams made without all three ingredients.

  • Method for preparing improved expanded polystyrene sheet
    Patent number: 4048208
    Abstract: Expanded styrene polymer sheet material is produced by extruding expandable and/or general purpose styrene polymer with a conventional blowing agent, a nucleating system and small amounts of finely divided hydrophilic silicon dioxide and alkaline earth metal oxide. The resulting product has very fine, uniformly sized pores and improved flexibility.
