Description générale

An oligomer of polyethylene glycol, tetra (ethylene glycol) (TEG) is a transparent, colorless, odorless, low volatility, hygroscopic liquid soluble in ethyl alcohol and very soluble in water.

Application

Used for the synthesis of tetraethylene glycol metha acrylate monomer.

Glow discharge plasma deposition of TEG renders surfaces resistant to protein adsorption and cellular attachment.

Attention

Do not confuse with glycofurol, which is also sometimes called tetraglycol.
