DMSO Industrial Grade Product Sheet

A TECHNICAL GRADE FOR BASIC APPLICATIONS

DMSO Industrial Grade is a technical grade of Dimethyl Sulfoxide, suitable for use in common industrial formulations (such as solvent cleaning applications and paint stripping). This nontoxic polar solvent plays an important role inthe synthesis and processing of polymers, including polyacrylonitrile (PAN) and polyethersulfone (PES).

Choose DMSO Industrial Grade for:

Cleaning Solutions

DMSO is an effective solvent for removing organic materials from equipment lines and manufacturing equipment. DMSO exhibits high solubility for many polymers and may aid in polymer processing and clean-up.

Paint Stripping

DMSO as a nontoxic alternative to more hazardous solvents in paint stripping formulations.

Polymer Processing

DMSO Industrial Grade is used as a reaction solvent in manufacturing a variety of polymers. Additional downstream applications include as a processing solvent in operations such as casting polymeric membranes and wet-spinning synthetic fibers.

Agrichemicals

Use as a reaction solvent in Active Ingredient synthesis and as a solvent in the formulation for delivery of the active.

Additional literature is available on the physical properties of DMSO , solubility data, health/safety information and engineering/ recycling guidance.
