Ethylene Glycol Semiconductor Grade

Product Overview

Ethylene Glycol Semiconductor Grade (also known as Monoethylene Glycol or MEG) is a high-purity, colorless, hygroscopic liquid engineered for the stringent requirements of the electronics and semiconductor industries. With a molecular weight of 62.07 g/mol and a boiling point of 197.3°C, this reagent-grade glycol ensures stable thermal management and low volatility in closed-loop systems.

This semiconductor grade material is characterized by strict assay control (Minimum 99.5% wt), exceptionally low trace metal levels, and minimal particulate contamination. It is designed for applications requiring precise temperature control, such as wafer processing, photolithography, and as a solvent in cleanroom environments. The product maintains compatibility with water and a broad range of organic solvents, supporting consistent performance in critical manufacturing workflows.

Safety & Handling

Handle Ethylene Glycol Semiconductor Grade in a well-ventilated area, avoiding contact with eyes, skin, and clothing. Wear appropriate Personal Protective Equipment (PPE), including chemical-resistant gloves and safety goggles. Store in a cool, dry place away from direct sunlight, strong oxidizers, and acids to maintain shelf-life stability (24 months). Ensure containers are tightly closed when not in use to prevent moisture absorption.
