PROCESS FOR PRODUCING SHAPED PHENOLIC FOAMS |
摘要 |
This invention is a partially- or semi-cured foam (2, 12) used to form the pipe insulation. The semi-cured foam is very flexible and can be formed around a pipe (4) 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 shaped (8, 18). Upon curing the foam retains the shaped of the perform. The semi-cured products is very flexible; once fully cured, the insulation becomes rigid.
