Zinc soaps for improved vulcanizates

Zinc carboxylates, which also is known as zinc, soap, are used in rubber manufacture for its curing and processing effects. A study into the ability of zinc soap to change vulcanization efficiencies in natural rubber was conducted. Research results indicate that the best vulcanization efficiencies in natural rubber were obtained from the use of an aromatic acid.
The use of zinc carboxylates as a multifunctional additive for both processing and curing effects has been described (ref. 1). The structure of the organic acid and concentration of the [...]
