| titleOfInvention | Phenol/formaldehyde resoles and cellular products derived therefrom |
| abstract | ABSTRACT OF THE DISCLOSURE The present invention provides particular phenol/formaldehyde resoles which are especially useful as formable resins, and further provides cellular phenolic products having physical properties which are especially attractive for end-use application as construction foam. The resoles are characterized by a particular relation-ship between their viscosity and water content, expressed as the area bounded by certain points on a plot of resole viscosity on a logarithmic scale, as a function of water content of the resole, the particular area depending upon the mole ratio of formaldehyde-to-phenol at which the resole has been condensed. It has been found that phenol-formaldehyde resoles having the defined viscosity/water relationship are capable of providing phenolic foam having acceptable foam processability, a foam density from about 1.90 to about 3.70 pounds per cubic foot and, within this foam density range, a good balance of friability resistance and compressive strength. that is, a friability of less than 35 percent weight loss and a compressive strength of at least 20 pounds per square inch. Preferred resoles within the invention are foamable to phenolic foam having a reduced tendency to punk as well as the aforementioned desirable combination of foam processability and mechanical properties. |
