Product Number:
-
14433
Product Description
Poly(acrylic acid) (PAA) Ultrapure MW 2,000 is a low–molecular weight, high-purity polyelectrolyte specifically engineered for use in demanding electronics and advanced manufacturing applications. Produced using proprietary purification methods, this ultrapure grade exhibits exceptionally low ionic and particulate content, making it well suited for critical environments where contamination control is essential.
This material is commonly used as a dispersant in chemical mechanical planarization (CMP) slurries and other precision formulations requiring tight molecular weight control and minimal trace metal content.
Key Features & Benefits
- Ultrapure Quality: Stringently purified to achieve very low ionic and particulate levels
- Low Molecular Weight (MW ~2,000): Promotes effective dispersion with minimal viscosity contribution and can effectively assist in removal of metal contaminates in post CMP cleaning formulations
- Electronics-Grade Performance: Designed for high-purity manufacturing environments
- Consistent Performance: Controlled molecular weight distribution for reproducible results
- Excellent Dispersant Properties: Strong interaction with inorganic particles and surfaces
Typical Applications
- CMP Slurries: Dispersant for stabilizing abrasive particles during planarization processes
- Post CMP Cleaners: Low molecular weight PAA assists in the removal of metal contaminates left after CMP processing while minimizing redeposition
- Electronics Manufacturing: Formulations requiring ultra-low metal contamination
- Precision Surface Processing: Particle stabilization and surface conditioning
- Advanced Aqueous Formulations: High-purity water-based systems
Functional Role
Poly(acrylic acid) functions as an anionic polyelectrolyte, providing electrostatic stabilization of particles in suspension. At low molecular weight, it offers rapid adsorption to particle surfaces and efficient dispersion without excessive viscosity contribution, making it ideal for tightly controlled formulations.
Handling & Storage
- Store in a cool, dry location away from incompatible materials
- Keep container tightly closed when not in use
- Protect from excessive heat and moisture
- Follow standard laboratory handling procedures for polymeric materials
