PEO MW 600k (CAS 25322-68-3) is linear high molecular weight water-soluble polyether polymer. Added to aqueous fiber slurry, hydrated polymer chains build adhesion points between fibers to reinforce nonwoven structure. It enhances dry and wet tensile strength and reduces fabric deformation during manufacturing. Thanks to superior water solubility, it acts as an ideal temporary binder that can be removed by water rinsing, leaving nearly no stains. It is an eco-friendly processing additive for hig

Product Detail

Product Overview

Polyethylene Oxide MW 600,000 (CAS 25322-68-3) is high-viscosity water-soluble PEO specially engineered for nonwoven industry. Medium molecular weight PEO cannot provide enough fiber binding force; ultra-high molecular weight PEO causes excessively high slurry viscosity and uneven web formation. This 600k grade achieves perfect balance between viscosity and bonding performance. When mixed with fiber suspension, the long polymer chains interconnect scattered fibers to increase fabric tenacity and resist shrinkage. As a water-soluble temporary binder, it can be washed off completely in subsequent water washing procedures, avoiding residual marks on finished nonwovens, which meets strict cleanliness requirements of medical and disposable wipe products.

Key Features

Molecular Weight: 600,000, CAS 25322-68-3, white free-flowing fine powder

Good fiber binding capacity, improve dry & wet tensile strength of nonwoven fabric
Optimize fabric dimensional stability, reduce shrinkage and deformation
Can be thoroughly washed out, low residue, no spots on nonwoven surface
Nonionic structure, compatible with most textile processing auxiliaries
Environmentally friendly, free of organic solvents

Main Applications

Temporary binder for wet-laid nonwoven fabric, spunlace nonwoven materials
Fiber bonding additive for disposable cleaning wipes and medical nonwoven products
Processing auxiliary for filter nonwoven and special industrial textile materials
Water-soluble binder for laboratory filter paper manufacturing

Usage Guidance

Gradually disperse PEO powder into continuously stirred deionized water to prevent agglomeration, prepare dilute solution before adding into fiber slurry. Recommended dosage: 0.2% ~1.5% based on fiber mass. Adjust dosage according to fabric grammage and target strength. Conduct small wet forming trial before mass production.

Storage & Package

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

Service Support

Test samples are available for pilot test. Stable bulk supply. We provide technical support for nonwoven production formulation. Welcome to inquire TDS, COA and factory quotation.
