  • What is vulkacit Dm/C?
  • Vulkacit® DM/C by Lanxess is di(benzothiazol-2-yl)disulfide-based vulcanization accelerator. It is a fast but very safe accelerator offering a steep slope on the rheometer curve. It also acts as anti-corrosion agent in boilers. It is suitable in manufacturing of textile auxiliaries, tires, tread, auto tubes, carcass, conveyor- and V-belts.
  • Why are there so many accelerators available?
  • The great variety of accel-erators available is a result of their diferent influences on the vulcanization kinetics (scorch and cure time) and on physi-cal properties such as tensile strength, elasticity or resist-ance to aging. In many cases, accelerators are combined to supply optimal processing and physical properties.
  • Is sulfur vulcanization a catalyst?
  • One of the key chemical reactions in this process is that of rubber with sulfur. Sulfur vulcanization, widely used in the rubber industry, requires the use of vulcanization accelerators such as Vulkacit®. Vulcanization accelerators are not catalysts because they are part of the chemical reaction.
  • How do antidegradants protect vulcanizates from aging?
  • Ozone or dynamic stress (fatigue) lead to cracking on the surface of the rubber article. Antidegradants such as Vulkanox® are chemicals which protect the vulcanizates against damaging external influ-ences. Depending on the chemical structure, they act against one or more of the aging processes mentioned.
