Product Description
Product Description
Poly(acrylic acid) (PAA) Highly Pure MW 2,000 is a low–molecular weight, high-purity polyelectrolyte designed for use in electronics manufacturing—particularly as a dispersant in chemical mechanical planarization (CMP) slurry systems. Polysciences’ proprietary purification methods help minimize ionic and particulate contaminants, supporting reliable performance in processes where cleanliness and consistency are critical.
This grade is part of a family of highly pure PAAs offered across multiple molecular weights, including options that may achieve “non-detect” ion levels when tested by ICP-MS.
Key Features & Benefits
- Highly Purified for Electronics Use: Produced using purification methods that reduce ionic and particulate contamination
- Low Ionic Content: Low levels of sodium, potassium, and chloride
- Low Conductivity: Helps support high-purity aqueous processing environments
- 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
- Reliable Performance: Suitable for precision formulations requiring reproducibility
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
- Semiconductor & Electronics Processing: High-purity formulations where ionic contamination must be minimized
- Precision Aqueous Formulations: Particle stabilization in water-based systems
- Advanced Materials Processing: Surface interactions and dispersion control in specialty manufacturing
Functional Role
Poly(acrylic acid) is an anionic polymer that can adsorb to particle surfaces and provide electrostatic stabilization in suspension. At MW ~2,000, it offers rapid surface interaction and efficient dispersion while limiting viscosity build—an advantage in tightly controlled CMP and electronics applications.
Handling & Storage
- Store in a cool, dry location in the original, tightly sealed container
- Protect from moisture and excessive heat
- Follow standard laboratory handling procedures and consult the SDS for guidance
