Dial-a-Durometer (DAD): A Versatile Approach for Polyurethane Elastomer Production

摘要

Dial-a-Durometer (DAD) is an elastomer production approach where one uses a low-hardness and high-hardness TDI prepolymer and blends the two to get any hardness in between. One can achieve a hardness from 70A to 75D using this approach. Physical/mechanical properties of these systems will be presented and compared to the traditional single prepolymer approach. The positives and negative of DAD will be presented. The versatility of this approach will be highlighted.
