| ADIPRENE L 100 urethane elastomer is one of a series of liquid urethane polymers which can be cured to a strong, rubbery solid by reaction of the isocyanate groups with polyamine compounds. When cured with MBCA¹ curing agent, ADIPRENE L 100 yields vulcanizates in the 88 to 92 Shore A hardness range. Lower hardness values and special properties can be obtained with other curing systems. Cured ADIPRENE L 100 has high tensile strength and resilience, as well as excellent resistance to abrasion, compression set, oils, solvents, oxidation, ozone, and low temperatures.&& |
