Polyethylene Oxide MW 4,000,000 (PEO 4M, CAS 25322-68-3) is linear ultra-high molecular weight water-soluble polyether polymer. It acts as core binder for 3D printing water-soluble support materials. During filament extrusion, PEO binds solid fillers uniformly to guarantee good extrudability and printing stability. After printing, the support structures can dissolve thoroughly in room-temperature water, which simplifies post-processing and prevents scratch or breakage of delicate model features.

Product Detail

Product Overview

Polyethylene Oxide MW 4,000,000 (CAS 25322-68-3) is high molecular weight PEO customized for 3D printing consumable industry. Low molecular weight PEO leads to insufficient binding force and poor filament toughness; ultra-high molecular weight PEO results in excessive melt viscosity and difficult extrusion. This 4M grade balances binding strength, melt processing property and water dissolution performance.

When blended with functional fillers and extruded into filaments, PEO forms continuous polymer network to maintain structural integrity during FDM printing. After forming, users only need to soak the workpiece in water to dissolve support parts, realizing non-destructive separation of support and prototype.

Key Features

Molecular Weight: 4,000,000, CAS 25322-68-3, white free-flowing fine powder
Strong binding performance for inorganic and organic fillers
Suitable for melt extrusion to produce water-soluble 3D printing filament
Good thermal processing stability within appropriate processing temperature range
Complete water solubility at ambient temperature, residue-free after dissolution
Great compatibility with various additives used in support material formula
Improve filament flexibility, reduce filament breakage during printing

Main Applications

Main binder for FDM 3D printing water-soluble support filament
Water soluble bonding polymer for powder bed 3D printing auxiliary materials
Raw material for removable sacrificial mold used in additive manufacturing
Functional binder for water degradable 3D printing composite materials

Usage Guidance

Dry blend PEO powder with fillers, plasticizers and other additives uniformly, then carry out twin-screw extrusion for filament production. Adjust plasticizer dosage and extrusion temperature according to target filament hardness and dissolution speed. Conduct extrusion test, printing test and water dissolution evaluation before mass production. Avoid overheating during processing to prevent polymer molecular chain degradation.
