| VIBRATHANE 6020 is a diphenylmethane diisocyanate terminated polyester based liquid prepolymer which yields an 85A durometer urethane when cured with l,4-Butanediol. This liquid prepolymer exhibits low viscosities at processing temperatures in addition to good heat stability. Some of the features of this high performance elastomer are: Outstanding abrasion resistance Lower isocyanate exposure High Tear Strength Good Dynamic Properties Low Compression Set&& |
