Pentachlorothiophenol cas 133-49-3

1. The product reacts with zinc sulfate solution to form zinc pentachlorothiophenol, which can be used as a plasticizing accelerator for natural rubber. It has significant chemical promotion effect for high and low temperature use, and is suitable for open mills and internal mixers.
2. The zinc pentachlorothiophenol has no effect on the physical properties, aging properties and chlorine smell of the vulcanizate, so it can be used for light-colored products.
3. It can also be used as a peptizer for rubbers containing unsaturated bonds such as natural rubber, cis-butadiene rubber, isoprene rubber, styrene-butadiene rubber, nitrile rubber, neoprene or butyl rubber. Good plasticity at low temperatures and small amount of sulfur has a stopping effect on its plastication.
