This invention relates to the production of low density resol foams from resol resins. The foams have a density of 2.0 pounds per cubic foot or less and are produced with a blowing agent of low boiling point HCFCs and perfluoroalkane.

Non-CFC foam produced using perfluoroalkanes

This invention relates to the production of low density resol foams from resol resins. The phenolic foams have a density of 2.0 pounds per cubic foot or less and are produced with a blended surfactant.

Non-CFC foam produced using blended surfactants

The invention relates to the preparation of closed cell phenolic resin foams produced from compositions of phenol-aldehyde resole resins, and the foam products thus prepared. More particularly the present invention relates to the preparation of phenolic resin foams by a method employing a novel modified phenolic foam catalyst. The invention also relates to these modified phenolic foam catalysts which include an aromatic sulphonic acid and resorcinol.

Modified phenolic foam catalysts and method

This invention relates to the manufacture of closed cell phenolic foams from low viscosity phenol-formaldehyde resole resin. This method of manufacture provides a foam which exhibits many of the advantageous characteristics of phenolic foams manufactured from high viscosity resole resin, including good thermal retention. There is provided a method of making a phenolic foam comprising the steps of mixing

Process for manufacturing closed cell phenolic foams

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
