Filed:

Aug 1, 2003

Appl. No.:

10/632343

Inventors:

John B. Letts - Carmel IN, US
Wayne E. Laughlin - California KY, US
Bruce M. Miller - Orange Park FL, US

International Classification:

C08J 9/12

US Classification:

521133, 521130, 521131, 521170, 4283044, 4284231

Abstract:

A method of manufacturing a polyisocyanurate foam insulation board, the method comprising contacting a stream of reactants that comprise an isocyanate-reactive compound with a stream of reactants that include an isocyanate compound to form a reaction product, where the step of contacting takes place in the presence of a blowing agent and a low-boiling inert gas, and where the amount of low-boiling inert gas present at the time of the contacting is sufficient to result in frothing of the reaction product.

US Patent:

53525108, Oct 4, 1994

Filed:

Sep 27, 1993

Appl. No.:

8/126864

Inventors:

Wayne E. Laughlin - Gulfport FL
Kenneth P. Klapper - Palm Harbor FL

Assignee:

The Celotex Corporation - Tampa FL

International Classification:

C08G 1808

US Classification:

4283044

Abstract:

A method for the manufacture of paper faced foam which comprises (a) applying a foam-forming mixture to at least one advancing cellulosic sheet or composite thereof with an air- and/or moisture-impermeable material, the cellulosic sheet (i) being impregnated with cured polyisocyanate, (ii) being sufficiently flexible for unwinding from a roll for conveyance along a production line and (iii) having a moisture content which does not exceed about 10 percent and is evenly distributed throughout the cellulosic sheet, and (b) foaming and curing the faced foam-forming mixture.

Appl. No.:

7/148393

Inventors:

David G. Gluck - St. Petersburg FL

Assignee:

The Celotex Corporation - Tampa FL

International Classification:

B32B 326
B32B 1710
B32B 2308
B32B 3114

US Classification:

4283177

Abstract:

A thermally insulating structural laminate comprising a core of rigid plastic foam having two major surfaces, at least one of the major surfaces of the foam being attached to a facer comprising a fribrous sheet having at least one layer of an air- and moisture-impervious polymer disposed on the inner surface thereof and interposed between the fibrous sheet and the foam, the oxygen transmission of the polymer being a value of less than about 1 cc/100 in. sup. 2 -24 hrs-atm sufficient to make the facer substantially impervious to the passage of air and water vapor, resulting in the long-term preservation of insulation value.
