Five Year Aging of Elastomeric Vulcanizates in Panama, Alaska and Illinois.
Vulcanizates prepared from commercially available elastomers were exposed outdoors in Alaska; Rock Island, Illinois; and the Panama Canal Zone to compare the effects of exposure to arctic, temperate, and tropic environments. Aging data collected on pads exposed as long as five years are presented as...
