摘要： A sheathing system that envelops a building structure is provided, combining lightweight structural layers and a high R-value insulation layer. The insulation layer includes a coated insulation product with a reduced fluorinated blowing agent concentration, while maintaining acceptable thermal properties. The coated insulation product includes a foam product that is coated with a barrier coating. The barrier coating includes a polymer having a minimum degree of crystallinity and at least one additive. The collective layers of the sheathing system offer the benefits of decreased thickness, reduced weight, improved thermal insulation, improved structural strength, improved nailability, improved fire performance, and enhanced energy efficiency.

摘要： This invention relates to a process for producing phenolformaldehyde foams, also known as phenolic foams, of improved properties. The inventive feature resides in using a controlled combination of the various components in the curing reaction mixture and in controlling the temperature within the mass of the curing mixture. The process is applicable to production of block or laminated foams. Phenolic foams find increasing use in building applications where their thermal insulation and fire resistant properties are of value.

摘要： This invention relates to flame retardant phenol aldehyde foams which have a k value below 0.020 W/mk. The foams have as flame retardants a blend of a halosubstituted diphenyl oxide and an organic phosphorus compound. The feature of the invention is that unlike conventional flame retardants, the blend now used does not adversely affect the low k value i.e. the low thermal conductivity of the foam.

摘要： This invention relates to the manufacture of foam from phenolic resins and to the foam so produced. In order to overcome some of the limitations of the prior art closed cell phenolic foams, we have developed a method of preparing closed cell foams from modified, low cost phenol formaldehyde resoles, which exhibit high closed cell contents, low friability and low thermal conductivity. This specification provides a foam competitive with urethane foams, which have an aged thermal conductivity of about 0.16K. or less, but which will not generate fumes as toxic as those of urethane. There is, provided a method of making a phenolic foam material comprising the steps of(1) preparing a base catalyzed phenol-formaldehyde resole having a mole ratio of phenol to formaldehyde of between 1:3 and 1:4.5 and containing substantially no free phenol but including residual formaldehyde;(2) neutralizing, concentrating and acidifying said resole;(3) reacting with co-reactants consisting essentially of urea and resorcinol in an amount such that the molar ratio of combined urea and resorcinol to free formaldehyde in said resole is about 1:1, the ratio of urea to formaldehyde being selected so that in a test starting at ambient temperature a reaction temperature of 70.degree. to 75.degree. C. is reached during foaming within a period of 4 to 8 minutes, the urea being reacted first where urea and resorcinol are separately reacted with the resole;(4) (a) combining the product of step 3 with a surfactant in an amount sufficient to be effective as a cell stabilizer and(b) a blowing agent in an amount sufficient to form a foam;(5) initiating foam formation by adding to the mixture of step 4 a catalyst comprising an acidic material to reduce the pH of the mixture to below 4;(6) curing the mixture of step 5.

摘要： An expandable blend of a linear olefinic polymer and a crosslinkable polymer for production of lightly crosslinked foamed polymers and a process for the preparation thereof is provided. The presence of a crosslinkable polymer component in the blend increases the melt strength of the linear olefinic component so that conventional melt processing techniques may be utilized to produce foamed polymers. Both open and closed cell foams may be produced.
