MANUFACTURING METHOD OF POLYURETHANE ELASTOMER, POLYURETHANE ELASTOMER, HDD STOPPER, USE OF INTERNAL MOLD RELEASE AGENT AND POLYURETHANE ELASTOMER RAW MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method of polyurethane elastomer capable of enhancing releasability with an internal mold release agent and preventing the internal mold release agent from becoming VOC, a polyurethane elastomer, an HDD stopper, a use of the internal mold release agent and a polyurethane elastomer raw material.SOLUTION: The manufacturing method of polyurethane elastomer, the polyurethane elastomer, the HDD stopper, the use of the internal mold release agent and the polyurethane elastomer raw material according to the present invention provide the polyurethane elastomer where the internal mold release agent binds to polyurethane by using the internal mold release agent having a functional group having affinity to polyurethane.SELECTED DRAWING: None
