| Andur 720-DP is the result of several years of research to develop a high performance, moderate cost prepolymer for the cast urethane industry. This new product is a poly-ester/ether, toluene diisocyanate-terminated prepolymer. An elastomer with a hardness of 70 Shore D is obtained by reaction with various polyols and their combination with Curene 442 and other diamine curatives. |
