Rodys R is an aqueous solution of sodium salt of naphthalene sulfonic acid formaldehyde (NSF) polycondensates with a dry substance content of 40%, and a low content of calcium and iron ions. The production technology of Rodys R allows obtaining a product that neither has an environmental classification, nor does it contribute to increase of the concentration of polycyclic aromatic hydrocarbons in finished products. As a dispersant, it is especially dedicated to emulsion polymerization of styrene-butadiene rubber (SBR), and can be an alternative to Rodys K.

Properties and applications
  • does not have an environmental classification;
  • allows obtaining latex dispersions stable during polymerization;
  • inhibits the formation of coagulates of latex particles during both polymerization and degasification;
  • leads to cost and time savings caused by cleaning of the polymerization system;
  • does not slow down the polymerization reaction rate;
  • does not adversely affect the physicochemical or mechanical properties of the produced rubber;
  • intended mainly as an auxiliary in the production of styrene-butadiene rubbers using emulsion polymerization.
