PE10657 Polyacrylic Acid Powder, PAA

Polyacrylic Acid Powder, PAA Description

Polyacrylic Acid Powder, PAA (CAS 9003-01-4) is a synthetic polymer available in powder form with a rigorously controlled molecular weight distribution. Manufactured through a precise polymerisation process, the material exhibits reproducible rheological behaviour, which is critical for adjusting viscosity in composite systems. Its chemical stability minimises interactions with other formulation components, thereby maintaining performance consistency in both development and production settings.

Polyacrylic Acid Powder, PAA Applications

1.       Industrial Composites
   - Used as a rheology modifier in composite resin formulations to adjust flow properties by leveraging its controlled molecular weight distribution.
   - Applied in cement additives to improve workability by controlling dispersion and water retention, ensuring uniform mixing.

2.       Coatings
   - Serves as a dispersing agent in water-based coatings to stabilise pigment dispersion through its chemical inertness, reducing sedimentation during processing.
   - Frequently used in formulation systems to optimise viscosity for consistent film formation.

Polyacrylic Acid Powder, PAA Packing

Polyacrylic Acid Powder, PAA is packed in multi-layer foil pouches, which are then placed inside rigid, sealed containers to protect against moisture and contamination. The packaging is designed to withstand handling and transport stresses whilst maintaining product integrity. Storage conditions include temperature-controlled and low-humidity environments. Custom packaging options—including specialised compartmentalisation and labelling—are available to meet specific logistical requirements.

Additional Information

Polyacrylic acid is a functional polymer widely utilised in both research and industrial applications due to its inherent anionic nature. The precise control over its molecular weight and dispersibility makes it a valuable tool for modifying the rheological properties of composite systems. Recent advances in polymerisation techniques allow for enhanced customisation, catering to diverse formulation needs.

Academic and industrial studies have shown that adjusting the chain length and particle size of polyacrylic acid directly influences its performance as a viscosity modifier. This understanding supports its application in complex systems such as advanced composites and coatings, where maintaining process consistency is essential for achieving desired material properties.
