Numerous sulfur chemicals are used in rubber applications, be it as vulcanisation accelerators, antioxidants or plasticizers.

BRUNO BOCK manufactures products which are distributed directly to our customers or we produce custom made products for customers as part of their rubber chemicals product portfolio.

MBT Ester

Methylene Bis(Butylthioglycolate), CAS# 14338-82-0, or MBT Ester, is used as plasticizer to flexibilise rubber articles like V-belts in the automotive industry. On one hand this ester shows a very low volatility and on the other hand excellent plasticising properties which make it suitable to be used in V-belts in a temperature range from -40°C to
140 °C.

Di(2-ethylhexyl) Thiodiglycolate

Another substance, CAS# 24293-43-4, also used as rubber additive.

EVANSTAB* 13, Ditridecyl Thiodipropionate, CAS# 10595-72-9, a liquid, is also used as antioxidant.
