Acrylic Acid (AA)

Description

Acrylic Acid (Glacial) is a highly reactive carboxylic acid used as a fundamental building block for a vast range of polymers and chemical intermediates in 2026.

Uses

Production of Superabsorbent Polymers (SAP) for diapers, polyacrylic acid (PAA) for water treatment, detergents, and as a precursor for acrylate esters (butyl acrylate, 2-EHA).

Benefits

High reactivity due to the double bond and acid group; provides excellent polymer chain growth and cross-linking capabilities.

Application Benefits

Thickening: Used in rheology modifiers for paints and cosmetics. Hydrophilicity: Imparts water-absorbing properties to copolymers. Adhesion: Enhances polar bonding in adhesives and sealants.

Storage & PackagingRecommendations: Store between 15°C and 25°C. If it freezes, it must be thawed very carefully with tempered water (max 35°C) to avoid localized overheating and polymerization. Never use steam for thawing. Packaging: Polyethylene-lined steel drums, HDPE drums, or stainless steel ISO tanks.
Product StewardshipAcrylic acid is susceptible to violent runaway polymerization. It must be inhibited (typically with MEHQ) and stored under an atmosphere containing 5–21% oxygen.
NOTENote: Always monitor inhibitor levels. If the liquid freezes, the inhibitor may be excluded from the crystals, creating a high-risk zone upon thawing.
NOTICEThis profile is based on 2026 industrial standards. You must consult the Official Safety Data Sheet (SDS) from your specific supplier before any physical handling.
Compliance & Standards

ISO 9001 (QMS), COA, MSDS/SDS, REACH (on request)

Highly Corrosive. Causes severe skin burns and eye damage. Vapors are irritating to the respiratory system. It is a combustible liquid.
