Petrochemical Intermediates

We produce BTX products -- benzene, toluene and xylene -- from the secondary distillation of crude benzene, a liquid by-product derived in conversion of coal into metallurgical coke used for pig iron and steel production. A substantial part of our crude benzene is procured from third parties. Benzene, toluene and crude xylene are critical inputs for several chemicals-based substances. Applications of toluene and crude xylene include use as solvents for inks and paints.

Superplasticizers

Superplasticizers

Superstructures such as bridges and high-rises require concrete with flowability, compressive strength, low air permeability, good resistance to wear and tear, and longevity. Superplasticizers are necessary to achieve these properties.

The market today demands a wide variety of concrete superplasticizers specifically designed to offer different product properties for different end-use applications. Rain Carbon develops, produces and markets the broadest range of these critical construction polymers available in the Americas’ marketplace. Our products improve the rheological, mechanical and flow properties of concrete, while increasing its strength, promoting compaction and providing optimum workability.

Product quality and reliability is why our RÜTGERS brand of high-performance polymeric dispersants were selected for construction of the 452-meter Petronas Twin Towers in Kuala Lumpur, one of the tallest buildings in the world.

Polynaphtalene sulfonate (PNS)

DISAL®

DISAL® is a sodium polynaphthalene sulfonate used as major ingredient in the formulation of various superplasticizer admixtures.

GYPFLOW® and GYPSPERSE

GYPFLOW® et GYPSPERSE are sodium and calcium salts of polynaphthalene sulfonates, specially formulated for the gypsum industry. They are designed to impart a strong anionic charge on gypsum particles to produce optimum dispersion of solids, and present many advantages:

 

  • Permit the use of low water/stucco ratios thus requiring lower energy usage per MSF
  • Allow instantaneous dispersion of solids in the mixer, due to their low viscosity producing fast dilution
  • Provide excellent fluidity to the gypsum slurry at very low concentration
  • Lower energy usage levels by decreasing excess water at the mixer
  • Respond to the demand for high speed, low cost manufacturing
  • Yield excellent results with natural and synthetic gypsum

SARATAN®

SARATAN® series is a family of low molecular weight sodium polynaphthalene sulfonates. SARATAN® is a highly effective dispersant for a wide variety of pigments, including carbon black, mineral colorants, organic dyestuffs, fillers, extenders and clays.

SARATAN® stabilizes and reduces viscosity of thick pastes and produces a smooth, uniformly wet paste without separation of the solid particles. Used in the leather industry, SARATAN® acts as a wetting and dispersing agent for staining dry leather, applying aqueous finishes and rewetting hides or crushed leather.

MANUFACTURE OF SYNTHETIC RUBBERS

Some specialized grades of SARATAN® products can be used in combination with primary emulsifiers such as fatty acid soaps, disproportionate rosin acid soaps to prepare high solid content latexes, very stable towards pH variation. A very fine floc or ‘gums’ tends to form during the emulsion polymerization of styrene-butadiene rubber, nitrile rubber, and polychloroprene despite the presence of efficient primary emulsifiers.

The addition of a secondary dispersant/emulsifier such as SARATAN® effectively minimizes the formation of gum.

 

A secondary dispersant is economically important because excessive gum formation in the reactors and in styrene stripping columns leads to frequent shutdowns for clean-up. SARATAN® minimizes such formation of gum and allows rubber production facilities to operate for considerably longer periods of time before shutdown.
