Description

Starch, Polymer With 2-Propenenitrile, Sodium Salt is a chemically modified starch derivative, specifically a graft copolymer of starch and polyacrylonitrile in its sodium salt form. This modification imparts unique water-absorbing and thickening properties, making it a valuable functional polymer for demanding industrial applications. It is primarily utilized in sectors requiring advanced superabsorbent materials, flocculants, and rheology modifiers.

Application

• As a superabsorbent polymer (SAP) in agricultural products for soil moisture retention and controlled-release fertilizers.
• As a flocculant and coagulant aid in water and wastewater treatment processes for clarifying industrial effluents.
• As a thickening and rheology control agent in the formulation of adhesives, coatings, and construction materials.
• In the paper and textile industries as a strength additive and sizing agent to improve product quality and process efficiency.
• For the development of hydrogel materials used in medical, personal care, and specialty packaging applications.
• As a dispersant and binder in ceramic processing and other industrial manufacturing.

Quality Control

Our Starch, Polymer With 2-Propenenitrile, Sodium Salt is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent performance, including assessment of absorption capacity, viscosity, and residual monomer content. Certificates of Analysis (COA) documenting purity and key specifications are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic nature, store in a cool, dry place at room temperature (15-25°C) with low humidity. Keep the container tightly sealed when not in use to prevent moisture absorption and caking.
