MICROCELLULAR ELASTOMERS WITH IMPROVED PROCESSABILITY AND PROPERTIES |
摘要 |
Microcellular polyurethane elastomer shoe sole components having exceptional physical properties may be prepared from isocyanate-terminated prepolymers derived from polyoxypropylene diols having a molecular weight of from about 2000 Da to 8000 Da, an unsaturation less than about 0.02 meq/g, and a random oxyethylene content of from about 5 to about 15 weight percent. The shoe sole components exhibit high tensile strength, elongation, resilience, and in addition have excellent tear strength, particularly 90 DEG angle tear.
