AMPS/ATBS is a highly versatile molecule used to make polymers, which has applications in a wide range of industries due to its excellent hydrolytic and thermal stability. This unique molecule imparts properties, such as divalent cationic stability, lubricity and enhanced performance at high temperatures to its polymers. We offer three grades of 2-acrylamido 2-methylapropane sulphonic acid: 2401, 2404 and 2406.


This product can be used in the following industries as given below:

Industry Applications Relevance
Polymers to enhance oil recovery ATBS copolymers are used in oil field environments as scale inhibitors, friction reducers and water-control polymers, and in polymer flooding applications.
Construction chemicals In drilling operations where conditions of high salinity, high temperature and high pressure are present, ATBS copolymers are used successfully to inhibit fluid loss.

In cementing operations within deep, high temperature wells, ATBS copolymers are used as non-retarding fluid loss control agents.

Detergents and cleaners Used to improve characteristics of hydrophilicity, dispersibility, and lubricity and also enhance the cleaning efficiency of detergents and Cleaners.
Raw material for water treatment Used in Cooling Tower and Boilers to inhibit Calcium, Magnesium and Silica scale formation. Also used to precipitate solids in industrial and mining effluents
Acrylic fibre Gives dye receptability for acrylic fibre
Textile auxiliaries Used as Textile Sizing Agents, Thickeners, Dispersants and Non-Woven Emulsion Binders.
Hydrogels and super absorbents Being super absorbents, they are used in diapers, lotions and other personal care products, due to high water absorbing capacity, electrical conductivity, slipperiness and lubricity. Also used as water retention agents
Adhesives Improve strength in pressure sensitive formulations and also make wood glue to improve adhesive strength, thermal and mechanical properties with superior rheology
Emulsions for paint and paper coating Polymers containing ATBS improve scrub resistance, dispersant performance and reduce grit formation
