Acrylic Acid (CAS 79-10-7), or Glacial Acrylic Acid (GAA), is a clear, colorless liquid with a strong, pungent odor. It is a critical reactive monomer used worldwide in the manufacturing of superabsorbent polymers, water treatment chemicals, acrylic esters, and industrial resins.
At Snowwhite Chemical Co., LTD., we supply industrial grade Acrylic Acid produced under strict quality control standards to support reliable, large-scale downstream chemical synthesis.

Primary Industrial Applications
1. Superabsorbent Polymers (SAP)
Acrylic Acid is the primary raw material for superabsorbent polymers. Polymerized GAA forms cross-linked sodium polyacrylate resins, which offer exceptional fluid retention capacity. These polymers are essential for personal hygiene products, such as baby diapers and adult incontinence pads, as well as agricultural moisture retainers.
2. Water Treatment Chemicals
By polymerizing Acrylic Acid alone or with co-monomers (such as maleic acid or acrylamide), manufacturers synthesize Polyacrylic Acid (PAA) and copolymer salts. These water-soluble polymers function as high-performance scale inhibitors and dispersants in industrial cooling towers, boiler systems, and wastewater facilities.
3. Acrylic Esters and Industrial Resins
GAA undergoes esterification with various alcohols to produce key acrylic esters, including:
• Butyl Acrylate (BA): Used in architectural paints, textile coatings, and decorative finishes.
• Ethyl Acrylate (EA): Applied in industrial coatings and fiber processing.
• 2-Ethylhexyl Acrylate (2-EHA): Provides flexibility in pressure-sensitive adhesives, tapes, and sealants.
Handling, Storage, and Safety Guidelines
Because Acrylic Acid is thermally sensitive and highly reactive, proper storage procedures are necessary to maintain product stability:
• Storage Temperature: Keep containers maintained strictly between 15°C and 25°C. The product crystallizes at temperatures below 13°C. If freezing occurs, thaw slowly in a temperate environment (20°C – 25°C); never heat containers above 35°C.
• Dissolved Oxygen Requirement: Do not blanket containers with 100% pure nitrogen. The MEHQ inhibitor requires dissolved oxygen to remain active. Maintain a dry air headspace in storage vessels.
• Material Compatibility: Store in 304/316L stainless steel or high-density polyethylene (HDPE) vessels. Avoid direct contact with mild steel, copper, or brass.
Frequently Asked Questions (FAQ)
Q1: What is the typical shelf life of Acrylic Acid with 200 ppm MEHQ?
When stored within the recommended temperature range (15°C – 25°C) with an adequate air headspace, the typical shelf life is 6 to 12 months from the production date.
Q2: How should I thaw Acrylic Acid if it crystallizes during cold weather transport?
Allow the product to melt naturally by transferring the container to a warm area (20°C – 25°C ) with gentle air movement. Do not apply direct steam or open flames, as localized heat can trigger rapid, exothermic self-polymerization.
