  • What is sulfur vulcanization?
  • Vulcanization is the conversion of a high-molecular mate-rial from the plastic to the elastic state. 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®.
  • What is vulkacit used for?
  • Used mainly for tires. Also suitable for dynamically stressed technical goods, e.g. bufers and conveyor belting, and for technical moldings and extrudates in general, e.g. seals, hoses, profiles, footwear, cable sheathing and insulation. Vulkacit® CZ (CBS) Vulkacit® NZ (TBBS)
  • 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.
  • What is vulkacit merkapto mercaptobenzothiazole used for?
  • Vulkacit® Merkapto and sodium mercaptobenzothiazole from LANXESS are excellent collectors for the flotation of many precious metals like gold, lead, molybdenum, platinum, silver, copper, nickel and zinc. NaMBT mercaptobenzothiazole serves as a flotation agent for the mining industry and as additive in various fluids.
  • 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.
  • What is vulkacit® merkapto?
  • With its nitrogen and sulphur functionality, Vulkacit® Merkapto is a very versatile molecule and used across several industries. Mercaptobenzothiazole (MBT) as well as benzothiazole (BT) are important intermediates in the synthesis of several active ingredients such as for pharma-ceutical and agricultural use.
