Title:
POLYURETHANE MATERIAL FOR MOLDING
Document Type and Number:
Japanese Patent JPH06287266
Kind Code:
A
Abstract:
PURPOSE: To obtain a polyurethane material having good fluidity, hardly trapping foam even in flowing through the interior of the cavity of a mold at a high speed and hardly leaving foam on the whole surface containing the terminal part of moldings and capable of reducing pinhole defect.
CONSTITUTION: In a polyurethane material consisting essentially of a polyol component and an isocyanate component, the polyol component is controlled so as to have 2500-4000 average molecular weight and a siloxane compound- based solvent and further silicone foam stabilizer are added to the material. This polyurethane material is e.g. injected into a cavity of a mold 11 reduced in pressure and expanded to carry out ISF (integral skin foam) coating 43.
