Description

Potassium Acrylate is the potassium salt of acrylic acid, a versatile monomer essential for synthesizing superabsorbent polymers (SAPs) and other specialty polymers. Its primary commercial value lies in its ability to form highly absorbent, cross-linked networks with superior ionic strength compared to sodium-based counterparts. This product is critical for manufacturers in the personal care, agriculture, water treatment, and construction chemical industries seeking to develop advanced materials with tailored absorption and rheological properties.

Application

• Superabsorbent Polymers (SAPs): The dominant application, used in the production of high-performance hygiene products such as diapers, adult incontinence pads, and feminine hygiene items.
• Agricultural Hydrogels: Formulated into soil conditioners and water-retention agents to improve moisture availability for crops, reduce irrigation frequency, and enhance seed germination.
• Industrial & Construction Sealants: Acts as a key monomer in water-swelling sealants and grouts used for waterproofing, crack injection, and tunnel construction.
• Waste Solidification: Employed to encapsulate and solidify liquid industrial waste, facilitating safer handling, transport, and disposal.
• Desiccant & Humidity Control: Used in the formulation of advanced desiccants for controlled environments in packaging and electronics.
• Specialty Adhesives & Coatings: Serves as a reactive component in the synthesis of pressure-sensitive adhesives and functional coatings.
• Research & Development: A crucial raw material for R&D laboratories developing novel polymer compositions and functional materials.

Quality Control

Our Potassium Acrylate is manufactured under a stringent quality management system. Every batch undergoes comprehensive analytical testing to ensure it meets precise specifications for purity, monomer content, and impurity profiles. A Certificate of Analysis (COA) detailing assay, moisture content, heavy metals, and other critical parameters is provided with each shipment to guarantee traceability and compliance with your formulation requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent caking and degradation. For long-term storage, consider using an inert atmosphere to minimize oxidation.
