Abstract
This invention relates to an accelerator system comprising a sulphur donor, a carbamate or combination of carbamates as the only accelerator and optionally sulphur and optionally an activator, characterized in that the carbamate is a zinc dihydrocarbyldithiocarbamate, or a combination of zinc dihydrocarbyldithiocarbamates; a composition comprising a synthetic isoprene polymer latex and the accelerator system, and dipped goods made therefrom.
Claims8
A composition comprising:
- (a) a synthetic isoprene polymer;
- and (b) an accelerator system with respect to 100 parts by weight of the synthetic isoprene polymer wherein the composition comprises:
- 0.5 to 10 phr of a thiuram as sulphur donor:
- 0.05 to 2.0 phr of a carbamate or combination of carbamates as the only accelerator and
- optionally at most 5.0 phr sulphur and
- optionally at most 2.5 phr of an activator, characterized in that the carbamate is a zinc dihydrocarbyldithiocarbamate, or a combination of zinc dihydrocarbyldithiocarbamates.
A good comprising a composition a comprising synthetic isoprene polymer latex and an accelerator system, comprising 0.5 to 10 phr of a thiuram as sulphur donor, 0.05 to 2.0 phr of a carbamate as the only accelerator and optionally at most 5.0 phr sulphur and optionally at most 2.5 phr of an activator, wherein the carbamate is a zinc dihydrocarbyldithiocarbamate, or a combination of zinc dihydrocarbyldithiocarbamates.
