VERFAHREN ZUM HERSTELLEN VON ELASTOMEREN POLYURETHANEN, INSBESONDERE IN FORM VON SCHUHSOHLEN

摘要

In the production of elastomeric polyurethanes, more particularly in the form of shoe soles, using a polyurethane reaction mixture, low-stability or non-storable premixes of polyol and crosslinking agent can be avoided and immediate changes can be made to the crosslinking agent without any losses if the isocyanate, polyol and crosslinking agent are separately delivered to the mixing chamber. Optional catalysts and/or blowing agents can also be separately delivered to the mixing chamber. The processing temperature of the polyol component may be 60 DEG to 150 DEG C.
