Abstract

This invention is a partially or semi-cured foam used to form the pipe insulation. The semi-cured foam is very flexible and can be formed around a pipe for a long period of time after production. The semi-cured phenolic foam board of this invention is a closed cell foam. The semi-cured foam is further cured in the formed shape. Upon curing the foam retains the shape of the preform. The semi-cured product is very flexible, once fully cured, the insulation becomes rigid.
