ATBS Monomer And ATBS Sodium Salt For Medium Molecular Weight Polymer

Our ATBS monomer and ATBS sodium salt enables polymer producers to manufacture superior and high quality polymers for use in a wide range of consumer and industrial products. We supply monomers in both granule and liquid forms with exceptionally high levels of product purity for optimum performance.

We produce ATBS monomers and ATBS sodium salts for polymers of different molecular weight. Our product series AP3131G granule and AP3132 liquid are designed specifically for medium molecular weight polymer.

ATBS Monomer AP3131G Granule

AP3131G is sulfonic acid acrylic monomer in granular form. The granular product reduces dust emissions resulting in a cleaner working environment, better worker safety and reduced plant maintenance. AP3131G does not agglomerate and is easy to transport. As AP3131G granulation is a post-reaction step, the ATBS monomer chemistry remains unchanged.

ATBS Sodium Salt AP3132 Liquid

AP3132 is sulfonic acid acrylic monomer in aqueous solution. It is produced by treating ATBS monomer with 50% sodium salt.

ATBS Monomer And ATBS Sodium Salt are widely used in water treatment, acrylic fiber, oilfield, latex and adhesive, emulsion coatings, personal care and medical and construction applications.

ATBS Monomer And ATBS Sodium Salt for medium molecular weight polymer (AP3131G Granule and AP3132 Liquid) are especially effective in the following applications:

  • Oil Field Applications: Due to their exceptional thermal and hydrolytic stability, AP3131G Granule and AP3132 Liquid are used in many oilfield applications where hostile environments demand high-performance products. Their unique hydrophilic nature, a tendency to increase viscosity and its divalent cation stability, also makes them the ideal solution for many oil field operations. In drilling operations, AP3131G Granule and AP3132 Liquid are used as scale inhibitors, friction reducers, non-retarding fluid loss control agent and water-control.
  • Latex and Adhesive Applications: AP3131G Granule and AP3132 Liquid are field-proven to achieve exceptional latex stability in high-performance latex coatings. The dispersion of solids in aqueous media is colloidally stable, improving the preparation of high solids emulsions. It improves the thermal and mechanical properties of adhesives, and increases the adhesive strength of pressure-sensitive adhesive formulations. Lower molecular weight polymers containing ATBS Monomer And ATBS Sodium Salt are especially effective dispersants for highly polar materials.
