PDMS
Flexible silicone compound
PDMS stands for polydimethylsiloxane, a silicon-based organic polymer widely used in industrial and consumer applications.
It's the main component in silicone oils, lubricants, and many cosmetic products.
In scientific research, PDMS is valued for making flexible molds and microfluidic devices: The lab cast the channels in PDMS.
