General description

Tris(2-ethylhexyl) trimellitate (TOTM) is a plasticizer mostly used for PVC based medical devices.
Visit our Sensor Applications portal to learn more.

Application

Plasticizer for solvent polymeric membrane electrodes
TOTM has been used as reference fluid for viscosity measurements using vibrating wire viscometer, to evaluate its use as a lubricant in the polymer industry.
