Polyethylene Oxide MW 10,000,000 CAS 25322-68-3 Ultra High Molecular Weight Grade for Extreme Drag Reduction
Polyethylene Oxide MW 10,000,000 (PEO 10M, CAS 25322-68-3) is linear ultra-high molecular weight water-soluble polyether polymer. When added into turbulent aqueous fluid, fully stretched long polymer chains absorb turbulent kinetic energy and restrain small vortex generation. It remarkably reduces frictional resistance on pipe walls, lowers pumping energy consumption and increases pipeline flow capacity. With superior intrinsic chain length, this grade delivers outstanding extreme drag reduction
Product Overview
Polyethylene Oxide MW 10,000,000 (CAS 25322-68-3) is top-tier ultra-high molecular weight PEO customized for extreme drag reduction scenarios. Medium molecular weight PEO cannot reach high drag reduction efficiency; excessively high molecular weight variants face difficult dissolution and severe shear degradation. This 10M grade balances ultimate drag reduction performance, water dispersibility and practical operability.After being prepared into dilute aqueous solution and injected into pipeline systems, entangled polymer chains interact with turbulent boundary layer. It suppresses turbulence fluctuation and achieves obvious pressure drop reduction under high Reynolds number flow conditions.
Key Features
- Molecular Weight: 10,000,000, CAS 25322-68-3, white free-flowing fine powder
- Ultra-long molecular chain structure, deliver excellent extreme turbulent drag reduction effect
- Significantly reduce pipeline friction loss, raise flow rate and save pumping power
- Take effect under ultra-low ppm-level concentration, cost-effective
- Good water solubility, convenient for continuous on-site liquid preparation
- Nonionic polymer, compatible with multiple water-based fluid systems
- Adaptable for neutral aqueous circulation pipeline environments
Main Applications
- Extreme drag reduction additive for long-distance industrial water pipeline transportation
- Flow improver for fire-fighting water supply pipeline systems
- Drag reducer for hydraulic circulation and large-scale irrigation piping

Usage Guidance
Slowly disperse PEO powder under continuous mild stirring to avoid agglomeration and fish-eye particles. Prepare low-concentration stock solution before pipeline injection. Typical working concentration range: 5~100 ppm. Conduct pipeline simulation drag reduction test to confirm optimal dosage before formal engineering application. Avoid intense high-shear stirring for long duration to prevent molecular chain breakage.
