Abstract
A flexible discontinuous process produces a series of at least two articles containing thermally insulating polyurethane foam from at least three streams (A), (B) and (C). The process involves mixing the at least three streams with different mixing ratios and injecting the mixture into cavities of the articles. A production unit can be used for performing this process.
