Description

General description

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.[1]

Glow discharge plasma deposition of TEG renders surfaces resistant to protein adsorption and cellular attachment.[1]

Packaging

100 g in poly bottle

1, 3 kg in poly bottle

20 kg in steel drum

Caution

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