Poly(acrylic acid) partial sodium salt
Poly(acrylic acid) partial sodium salt (CAS 76774-25-9) is a hydrophilic polymer with a molecular weight dependent on its degree of polymerisation. It is known for its water-absorbing properties and its ability to form gels. This material finds significant application in the manufacturing of disposable absorbent products such as diapers, and also in moisture barrier tapes, coatings, and humidity control systems. Its unique properties make it valuable in various material science applications.
Absorbent Products
Utilised as a key component in disposable products like diapers, where its high absorbency efficiently manages moisture. It contributes to the overall performance and comfort of these essential items.
Moisture Barrier Tapes and Coatings
Incorporated into the formulation of moisture barrier tapes and coatings, providing effective protection against water ingress in various industrial and consumer applications. It enhances the durability and functional integrity of coated surfaces.
Humidity Control
Employed in systems designed for humidity regulation, leveraging its hygroscopic nature to absorb or release moisture as needed, thereby maintaining a stable atmospheric environment.
Gel Actuators
Serves as a component in the development of gel actuators, where its swelling behaviour in response to environmental changes can be harnessed for mechanical actuation and responsive materials.
