Product Description
Poly(acrylic acid) (PAA) Highly Pure MW 10,000 is a high-purity, mid–molecular weight polyelectrolyte designed for electronics manufacturing applications—especially as a dispersant in chemical mechanical planarization (CMP) slurry systems. Polysciences’ proprietary purification methods help produce PAAs with low ionic content and low particulate content, supporting cleaner processing and more consistent performance in contamination-sensitive environments.
Highly Pure PAA is available 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: Designed to help minimize common ionic species in high-purity processes
- Low Particulate Content: Supports cleaner formulations and reduced contamination risk
- MW ~10,000: Balanced molecular weight for dispersion performance and formulation stability
- Reliable in Aqueous Systems: Suitable for high-purity, water-based formulations
Typical Applications
- CMP Slurries: Dispersant for stabilizing abrasive particles in semiconductor planarization
- Semiconductor & Electronics Processing: For formulations requiring low ionic/particulate contamination
- Precision Aqueous Formulations: Particle stabilization and suspension control
- Advanced Materials Processing: Where consistent dispersion and cleanliness are important
Functional Role
Poly(acrylic acid) functions as an anionic polyelectrolyte that can adsorb to particle surfaces and provide electrostatic stabilization in suspension. At MW ~10,000, it can offer strong particle interaction and improved dispersion stability while maintaining manageable viscosity—supporting performance in CMP and other precision aqueous systems.
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
Frequently Asked Questions (FAQs)
What does “highly pure” mean for this product?
It indicates the polymer is produced using purification methods intended to reduce ionic and particulate contaminants compared with conventional grades, supporting electronics manufacturing needs.
How does PAA help in CMP slurries?
It is used as a dispersant to help stabilize abrasive particles, improve suspension uniformity, and support consistent planarization performance.
Why select MW ~10,000 instead of lower molecular weight PAA?
A mid–molecular weight like ~10,000 can provide stronger steric/electrostatic stabilization and improved dispersion persistence, which may benefit certain slurry chemistries and particle systems.
Are other molecular weights available?
Yes. Polysciences offers Highly Pure PAA at multiple molecular weights, including some options that may test at “non-detect” ion levels by ICP-MS.
Is this product intended for contamination-sensitive applications?
Yes. This product is designed for electronics and other high-purity uses where low ionic and particulate content are important.
