Polyethylene Oxide (PEO, CAS 25322-68-3) is linear nonionic water-soluble polyether polymer applied as key binder component for Metal Injection Molding (MIM) and Ceramic Injection Molding (CIM). During feedstock compounding, PEO effectively wets metal and ceramic powders, optimizing melt flow property for injection molding. It significantly improves green body toughness to avoid cracking during handling. The polymer can be extracted by water debinding to form interconnected pore channels, facili

Product Detail

Product Overview

Polyethylene Oxide CAS 25322-68-3 is high purity water-soluble thermoplastic polymer designed for powder injection molding binder systems. Traditional binder formulas often suffer poor powder wettability, fragile green parts or heavy carbon residue after sintering. This PEO grade offers balanced rheology, excellent powder compatibility and clean debinding performance. It supports water-based solvent debinding process, lowers production hazard and reduces part defects for precision MIM & CIM component manufacturers.

Key Features

CAS Number: 25322-68-3, Appearance: White free-flowing fine powder
Outstanding wetting capacity for metal powder and ceramic powder
Improve feedstock flowability for smooth injection molding
Increase green body strength, reduce breakage during demolding and transportation
Water soluble, available for environment-friendly water debinding process
Forms continuous pore network after solvent extraction, accelerates thermal debinding
Low ash & low carbon residue after high temperature pyrolysis
Compatible with backbone polymers, waxes and dispersants in multi-component binder systems

Main Applications

Water-soluble binder ingredient for Metal Injection Molding (MIM) feedstock
Binder additive for Ceramic Injection Molding (CIM), alumina & zirconia forming
Functional component for powder injection molding eco-friendly binder formulation
Auxiliary binder for titanium alloy, stainless steel and technical ceramic precision parts

Usage Guidance

Blend PEO with backbone polymer, wax and dispersant according to binder formula. Conduct twin-screw compounding together with metal/ceramic powder under controlled temperature. Avoid excessive processing shear to prevent polymer chain degradation. Optimize debinding temperature and immersion time based on part thickness. Complete small-scale trial production before mass manufacturing.

Storage & Package

Seal tightly. Store in cool, dry, dust-free warehouse, prevent moisture absorption, overheating and direct sunlight. Standard package: 25kg kraft bag with inner PE liner. Shelf life: 12 months under proper sealed storage.
