ABSTRACT:
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
