General description

Poly(ethylene glycol) bis(2-ethylhexanoate) (PEG-EH) is an ethylene acrylic elastomer that can be used as a low volatile plasticizer.

Application

PEG-EH can form a blend with polyvinylidene fluoride (PVDF) which can be used in the preparation of electrolytes for lithium batteries. It is also used as an additive for the development of ionization methods for mass spectroscopy.

Features and Benefits

Low volatility and good heat resistance. Compatible with a variety of polymers including polyesters and polyamides.
