Why the "Stabilized" Aspect of Acrylic Acid is Paramount
The emphasis on the "stabilized" nature of Acrylic Acid is not merely a quality feature; it's a critical safety requirement. Acrylic Acid possesses an inherent and strong tendency to polymerize, which can lead to hazardous situations if not properly managed:
Risk of Uncontrolled Polymerization:
Polymerization is a highly exothermic (heat-releasing) reaction. If this reaction occurs uncontrollably within a container, the rapidly generated heat can cause a dangerous increase in temperature and pressure. This can lead to the container rupturing violently or even exploding, releasing hot, corrosive, and flammable Acrylic Acid and its vapors, posing severe risks of fire, chemical burns, and environmental contamination.
Factors Triggering Instability:
Even with stabilizers, certain conditions can compromise Acrylic Acid’s stability and initiate uncontrolled polymerization:
Elevated Temperatures: Excessive heat can override the inhibitor's effectiveness.
Contamination: Trace impurities, especially metal ions (like iron or copper), strong acids, strong bases, or free radical initiators, can act as catalysts.
Loss of Inhibitor Effectiveness: The inhibitor (e.g., MEHQ) requires the continuous presence of oxygen (usually air) to function properly. Storage under an inert atmosphere or oxygen depletion can render it ineffective.
Freezing and Improper Thawing: If the acid freezes, the inhibitor may separate. Improper thawing (e.g., localized heating) can lead to polymerization in uninhibited areas.
Aure Chemical's Commitment to Stability:
We ensure our Acrylic Acid is properly inhibited and provide clear guidelines for storage and handling, requiring temperature control and appropriate oxygen exposure to maintain stability throughout its shelf life and transport.
The controlled reactivity of stabilized Acrylic Acid, combined with its ability to form long polymer chains, makes it indispensable across diverse industries:
Superabsorbent Polymers (SAPs):
The single largest application of Acrylic Acid is in the production of Superabsorbent Polymers (SAPs). These polymers can absorb and retain extremely large amounts of liquid relative to their own mass, making them essential components in disposable diapers, adult incontinence products, and feminine hygiene products.
Coatings, Adhesives, and Sealants:
Acrylic Acid is a key monomer in the production of acrylic polymers and copolymers used in various high-performance coatings, adhesives, and sealants. These products offer excellent adhesion, weatherability, color retention, and flexibility.
Thickeners and Dispersants:
Polyacrylates derived from Acrylic Acid serve as effective thickeners, dispersants, and rheology modifiers in applications ranging from paints and detergents to cosmetics and oilfield chemicals.
Flocculants and Water Treatment Chemicals:
Polymers based on Acrylic Acid are widely used as flocculants in water treatment processes, helping to clarify water by causing suspended particles to clump together.
Other Chemical Intermediates:
It acts as a versatile chemical intermediate for the synthesis of esters (acrylates), which are then used in the production of specialty polymers and various chemical products, including certain plasticizers and chemical auxiliaries.

Packaging, Transportation & Storage Solutions
At Aure Chemical, we understand the critical importance of rigorous packaging, transportation, and storage for chemical products. To ensure the safety and integrity of the products you purchase, and to comply with international and national regulations, we provide the following general guidelines. Please note that each specific product has its own Safety Data Sheet (SDS), which contains the most detailed and authoritative information on packaging, transportation, and storage. We strongly advise you to consult and strictly adhere to the SDS for the respective product.
| I. Packaging Solutions | II. Transportation Solutions | III. Storage Solutions |
We utilize various UN (United Nations) certified packaging containers based on the chemical nature, hazard class, and transportation requirements of our products. Common packaging types include, but are not limited to: Steel Drums: Suitable for a wide range of liquid and solid products, especially flammable liquids. Plastic Drums/Jerricans: Primarily used for corrosive liquids like acids and bases, or substances incompatible with metal. Composite Drums: Combine the corrosion resistance of a plastic inner liner with the strength of a steel or fiber outer shell. IBCs (Intermediate Bulk Containers): Often referred to as "Tote Bins" or "Cubic Tanks," these are used for larger volumes of liquid or solid dangerous goods, offering efficient storage and transport solutions. Lined Bags or Fibre Drums: Primarily used for powdered or granular solids. Glass Bottles: Typically used as inner packaging for small quantities of high-purity or specialized chemicals, requiring additional absorbent material and sturdy outer packaging (e.g., wooden crates, fiberboard boxes). Steel Cylinders: Specifically designed and constructed as pressure vessels for the storage and transport of compressed, liquefied, or dissolved gases. Available in various capacities and pressure ratings, they are built to withstand high internal pressures and ensure the safe containment of gaseous substances.
All packaging undergoes stringent testing and complies with UN packaging performance levels to ensure product safety under normal transport conditions. | We strictly adhere to international and regional regulations for the transport of dangerous goods, ensuring full compliance and safety from our facility to your delivery point.

Other Necessary Certifications or Documents: Such as Certificates of Analysis (COA).
Upon receiving your shipment, please carefully verify the integrity of the packaging and the label information.
| Proper storage is crucial for maintaining product quality and ensuring operational safety. The following are general storage principles: Dedicated Areas: Dangerous chemicals should be stored in designated warehouses or areas that meet safety standards, away from residential zones and densely populated areas. Segregated Storage: Strictly classify and segregate products according to their hazard class to prevent incompatible substances from being stored together and causing dangerous reactions (e.g., acids and bases separated, flammables away from oxidizers). Good Ventilation: Storage areas should maintain good natural or forced ventilation to prevent the accumulation of hazardous gases or vapors. Temperature & Humidity Control: Control the temperature and humidity of the storage environment according to the recommendations in the SDS. Avoid direct sunlight and extreme temperatures. Fire and Explosion Prevention: Storage areas for flammable and explosive products should be equipped with adequate fire-fighting equipment, prohibit open flames, and ensure electrical equipment meets explosion-proof standards. Clear Labeling: All storage containers and areas should have clear, conspicuous hazard labels and warning signs. Spill Response: Storage areas should be equipped with appropriate spill response equipment and materials, and personnel should be familiar with emergency procedures. Regular Inspections: Periodically inspect the integrity of storage containers to ensure no leaks or damage, and verify label information. Away from Food and Drinking Water: Avoid cross-contamination.
