Description

General description

Poly(dimethylsiloxane) (PDMS), also known as dimethicone, is an organosilicon compound that is widely used as a siloxane based elastomer. It is a hydrophobic material with attractive physical and chemical properties such as elasticity, optical transparency, tunable surface chemistry, and low electrical conductivity.

Application

PDMS can be used in microfluidic devices, nanolithography, and other membrane based applications.

Packaging

50 mL in glass bottle
