摘要: Methods of manufacturing wall structures having high racking strength are described in this specification. The methods include spray applying a foam-forming composition into a cavity of a wall structure, wherein the wall structure is disposed in a climate-controlled spray application station and allowing the foam-forming material to expand within at least a portion of the cavity to form a foam layer deposited in the cavity. In the methods, the foam layer is formed in-situ during the manufacturing method, and the density of the foam layer is selected and the relative humidity and dew point of the air in the climate-controlled spray application station throughout the spray applying is selected so that the wall structure has a racking strength of at least 500 pounds per linear foot.

摘要: HCFO-containing isocyanate-reactive compositions, foam-forming compositions containing such isocyanate-reactive compositions, rigid PUR-PIR foams made using such foam-forming compositions, and methods for producing such foams, including use of such foams as insulation in discontinuous foam panel applications. The isocyanate-reactive composition includes a polyol blend, a blowing agent composition, and a tertiary amine catalyst. The polyol blend includes: (1) an aromatic polyester polyol having a functionality of 1.5 to less than 2.5 and an OH number of 150 to 360 mg KOH/g; (2) an aromatic polyester polyol having a functionality of at least 2.5 and an OH number greater than 360 mg KOH/g, which is present in an amount of at least 10% by weight, based on the total weight of the aromatic polyester polyol in the polyol blend; and (3) an amine-initiated polyether polyol having an OH number of at least 500 mg KOH/g and a functionality of 2.5 to 4. The blowing agent composition includes a hydrochlorofluoroolefin and a carbon dioxide generating chemical blowing agent.

摘要: Disclosed are methods, systems and computer program products for producing and applying a spray foam producing mixture onto a surface, and imaging a spray cone, or the applied surface, using an infrared or an optical imaging device to capture an image, and then determining, based on the captured image, if a defect that requires correction exists in the spray cone or in the applied surface; and optionally, in response to determining that a defect requiring correction exists, modifying a process parameter in producing or applying spray foam.

摘要: Foam wall structures and methods for making them are described. The wall structures include a frame, a foam panel overlying a front surface of the frame, and a polyurethane foam layer disposed in a cavity of the wall structure. The polyurethane foam layer has a density, as determined by ASTM D1622-14, of at least 44 kg/m3 and exhibits ASTM E84-16 Class A flame spread and smoke development characteristics. The polyurethane foam layer is the cured reaction product of a polyurethane foam-forming composition that includes a polyisocyanate, an aromatic polyester polyol having a functionality of greater than 2.5 and an OH number of at least 300 mg KOH/g, which is present in an amount of at least 50% by weight, based on the total weight of the polyurethane foam-forming composition less the weight of the polyisocyanate, a catalyst, and a blowing agent composition. The blowing agent composition includes water and a hydrofluoroolefin.

摘要: Foam wall structures and methods for making them are described. The wall structures include a frame, a foam panel overlying a front surface of the frame, and a polyurethane foam layer disposed in a cavity of the wall structure. The polyurethane foam layer has a density, as determined by ASTM D1622-14, of at least 44 kg/m3(2.75 lb/ft3) and exhibits ASTM E84-16 Class A flame spread and smoke development characteristics. The polyurethane foam layer is the cured reaction product of a polyurethane foam-forming composition that includes a polyisocyanate, an aromatic polyester polyol having a functionality of greater than 2.5 and an OH number of at least 300 mg KOH/g, which is present in an amount of at least 50% by weight, based on the total weight of the polyurethane foam-forming composition less the weight of the polyisocyanate, a catalyst, and a blowing agent composition. The blowing agent composition includes water and a hydrofluoroolefin.
