Polyethylene Oxide MW 10,000,000 (PEO 10M, CAS 25322-68-3) is linear ultra-high molecular weight water-soluble polyether polymer. Incorporated into adhesive formulations, entangled polymer chains form stable three-dimensional network structure. It effectively increases system viscosity, optimizes thixotropic property, prevents sagging during construction and enhances interfacial adhesion. This grade offers outstanding thickening efficiency, making it an ideal multifunctional thickening and reinf

Product Detail

Product Overview

Polyethylene Oxide MW 10,000,000 (CAS 25322-68-3) is ultra-high molecular weight PEO developed for high-performance adhesive production. Medium molecular weight PEO shows insufficient thickening effect; excessively high molecular weight varieties cause poor dissolution and over-high viscosity which hinders processing. This 10M grade balances thickening capacity, rheology regulation and production operability.

After uniform dispersion in adhesive raw materials, polymer networks improve coating uniformity and mechanical bonding performance of cured adhesives, satisfying the demands of heavy-duty industrial bonding applications.

Key Features

Molecular Weight: 10,000,000, CAS 25322-68-3, white free-flowing fine powder
Excellent thickening efficiency at low addition amount
Improve thixotropy, enhance anti-sagging and anti-flowing performance
Strengthen internal cohesion and interfacial bonding strength of adhesives
Good compatibility with water-soluble polymers, emulsions and various auxiliaries
Optimize leveling property for coating and bonding construction
Stable performance under neutral and weakly alkaline adhesive systems

Main Applications

Premium thickener for water-based industrial composite adhesives
Rheology modifier for pressure-sensitive adhesives and assembly glues
Reinforcing additive for construction bonding agents and sealant pre-polymers
Functional thickening raw material for special environmental-friendly waterborne adhesives

Usage Guidance

Slowly disperse PEO powder under gentle continuous stirring to avoid agglomeration and fish-eye particles. Adjust dosage according to target viscosity and construction requirements. Complete rheology test, sagging resistance test and bonding strength test before mass production. Avoid long-time high-temperature treatment to prevent molecular chain degradation.
