Vulcanization of rubber is easily performed in DuBois rubber curing salts. Our solutions allow for high throughput of assorted rubber moldings used in automotive components, windows and doors. DuBois molten salts have excellent thermal and chemical stability to ensure complete continuous vulcanization. They are quickly rinsed off complex profiles in using spray rinsing or by complete immersion in water. DuBois rubber curing salts offer the following characteristics:

  • A nitrite-free formulated salt to eliminate the possible formation of nitrosamines
  • Will not react with the surface of rubbers at temperatures below 500˚F
  • Eutectic mixtures to achieve the lowest possible melting points
