A process for the preparation of a molded polyurethane clastomero.

摘要

Process for the preparation of a polyurethane elastomer Molded by Fusion reaction.Is a Aromatic plissocianato REACT normally methylene - bis (4 - fenilisocianato polio), a high molecular weight and a Chain extension agent, elilenglicol, where a triol polyol that is a joint contitne internal segment of Propylene Oxide ethylene oxide proportions in pes Or 65 - 98% for the first and 2 - 35 per 100 for the second.To produce a Foam formulation. This formulation is injected into a Mold Cavity of the desired Configuration by a RIM Machine. It desmoldea article from the previous stage.
