Abstract
Elastomer compositions are provided which contain high molecular weight water-insoluble humic acid humates. The compositions show improved bloom resistance in both the uncured and the vulcanized or otherwise cured state. Methods to make sponge rubber are also disclosed in which the humic acid humate is the gas producing agent. A predominantly humic acid humate containing composition maintains a clean mold, and curing an uncured article coated with the humate at elevated temperature will clean metal molds which have dirty surfaces, particularly when green coated articles are vulcanized in contact with the mold's surfaces.
