摘要： The present invention provides processes for producing re-bonded polyurethane foam constructs that are useful in applications such as carpet underlayments. According to the invention, a tertiary amine is employed as a catalyst either alone, or preferably in combination with other catalysts in a binder which comprises an organic isocyanate and a polyol. Inclusion of a tertiary amine as a catalyst dramatically increases production throughput.
