Ethylene Glycol: Semiconductor-Grade Overview

Ethylene Glycol: A Semiconductor-Grade Essential

Ethylene glycol, especially in its semiconductor-grade form, is integral in various high-tech industries due to its purity and consistency.

Chemical Properties

Ethylene glycol, with the chemical formula C2H6O2, is known for its hygroscopic nature and capability to lower the freezing point of water.

Appearance and Odor

Typically, it’s a clear, colorless, and odorless viscous liquid, making it suitable for precise industrial applications.

Boiling and Melting Point

It has a boiling point of approximately 197.6°C and a melting point of about -12.9°C.

Solubility and Density

Ethylene glycol is completely miscible with water. Its density is about 1.1132 g/mL at 20°C.

Applications in Semiconductor Industry

In the semiconductor industry, the purity of materials is paramount. Semiconductor-grade ethylene glycol, due to its high purity, is preferred for certain applications.

Cooling Medium

Its ability to dissipate heat effectively makes it an ideal cooling medium in semiconductor manufacturing processes.

Dehumidifying Agent

Its hygroscopic nature enables it to prevent moisture-related complications in sensitive semiconductor environments.

Handling and Storage

Handling and storing semiconductor-grade ethylene glycol requires specific precautions to maintain its purity and effectiveness.

Protective Measures

Use of protective gear like gloves and safety goggles is recommended. Proper ventilation is crucial to ensure safety, especially during spillages.

Storage Conditions

It should be stored in a cool, dry place, preferably in tightly sealed containers to prevent contamination and moisture ingress.


Semiconductor-grade ethylene glycol, with its high purity and specific properties, plays a pivotal role in the high-tech semiconductor industry. Ensuring adherence to handling and storage guidelines is vital for its optimal performance in sensitive applications.
