Polyethylene Oxide (PEO, CAS 25322-68-3) is linear nonionic water-soluble polyether polymer designed as sacrificial support raw material for FDM 3D printing. It possesses matched melt processing temperature, maintains structural stability during layer-by-layer extrusion. After printing, the support structure can dissolve completely in room-temperature water without damaging printed workpieces. It greatly simplifies post-processing for intricate, enclosed and hollow models. It is an ideal raw mat

Product Detail

Product Overview

Polyethylene Oxide CAS 25322-68-3 is high-purity water-soluble polymer specially developed for manufacturing FDM 3D printing soluble support filament. Traditional mechanical supports require tedious manual stripping and easily cause workpiece surface scratches. This PEO grade exhibits balanced melt rheology for filament extrusion and stable printing property. The support dissolves cleanly in water, enabling high-precision complex model production and lowering post-processing labor costs for additive manufacturing factories.

Key Features

CAS Number: 25322-68-3, Appearance: White free-flowing fine powder
Suitable melt viscosity, easy for twin-screw extrusion into 3D printing filament
Stable dimensional performance during FDM printing, less warpage and sagging
Completely soluble in room temperature water, no residual contaminants on printed parts
Good interlayer adhesion, reliable supporting effect for overhang and hollow structures
Excellent compatibility with PLA, ABS, PETG, TPU and other mainstream FDM materials
Multiple molecular weight grades adjustable to match different printing temperature requirements
Low impurity content, stable batch consistency for continuous filament production

Main Applications

Raw polymer for producing FDM water-soluble support filament
Sacrificial material for printing complex hollow, interlocking and enclosed structural models
Water dissolvable mold material for small-batch precision prototype manufacturing
Research raw material for developing novel multi-material 3D printing composite formulas

Usage Guidance

Blend with auxiliary additives according to formulation requirements before twin-screw granulation and filament extrusion. Control processing temperature reasonably to avoid thermal degradation. Dry the raw material sufficiently before extrusion to prevent bubbles inside filament. Conduct small-batch extrusion and printing tests to confirm optimal formula and processing parameters.

Storage & Package

Keep tightly sealed. Store in cool, dry warehouse, protect against moisture, high temperature and direct sunlight. Standard package: 25kg kraft bag with inner PE liner. Shelf life: 12 months under proper sealed storage.

Service Support

Lab samples available for filament formulation research. COA and TDS documents can be supplied. Stable bulk supply capacity. Welcome to inquire factory quotation.
