Polyethylene Oxide MW 5,000,000 (PEO 5M, CAS 25322-68-3) is linear ultra-high molecular weight water-soluble polyether polymer. When prepared into aqueous solution and sprayed on bulk material surfaces, extended polymer chains capture fine dust particles and build cohesive network. It forms flexible anti-dust crust, effectively preventing PM2.5 and PM10 particles from being blown away by wind. The product features lasting dust suppression effect, excellent moisture retention and wide pH adaptabi

Product Detail

Product Overview

Polyethylene Oxide MW 5,000,000 (CAS 25322-68-3) is specially developed ultra-high molecular weight PEO for industrial dust control. Medium molecular weight PEO cannot form durable binding crust; excessively high molecular weight grades cause excessive solution viscosity and difficult field spraying. This 5M grade balances particle binding capacity, solution fluidity and film-forming performance.

After water dissolution and surface spraying, polymer chains connect scattered dust fines together. A continuous flexible protective layer is formed on ore stockpiles, haul roads and bulk cargo yards to reduce fugitive dust pollution under wind and vehicle disturbance.

Key Features

Molecular Weight: 5,000,000, CAS 25322-68-3, white free-flowing fine powder
Ultra-long molecular chain with powerful adsorption and particle binding capacity
Form flexible anti-dust crust, resist wind erosion and light rain washout
Good moisture retention to prolong dust suppression cycle
Nonionic structure, stable performance in various water quality and pH conditions
Low application dosage, convenient for on-site dilution and spraying
Environmentally friendly, low toxicity, no serious corrosion to equipment

Main Applications

Dust suppressant raw material for coal mines, metal ore stockpiles and tailing yards
Anti-dust polymer for construction sites, gravel roads and quarry transportation roads
Fugitive dust control additive for bulk cargo storage yards and port terminals
Functional binder for road maintenance dust suppression liquid formulations

Usage Guidance

Gradually disperse PEO powder into continuously stirred water to avoid agglomeration and fish eyes. Prepare dilute working solution on site. Usual spraying concentration: 0.01% ~ 0.08%. Adjust concentration according to wind conditions, material type and required maintenance cycle. Complete field small-scale spraying test before large-area construction.

Storage & Package

Seal packages tightly. Store in cool, dry and ventilated warehouse. Prevent moisture absorption, high temperature and direct sunlight. Standard package: 25kg kraft paper bag with inner PE liner. Shelf life: 12 months under proper sealed storage.

Service Support

Test samples available for dust suppression formula evaluation. Stable bulk supply. We provide technical support for dust control liquid formulation. Welcome to inquire TDS, COA and factory quotation.
