PDMS

Polydimethylsiloxane (PDMS) is a silicone-based polymer characterized by a Si-O backbone with methyl groups, offering exceptional flexibility, thermal stability, and chemical inertness across a broad service temperature range. It is widely used in medical devices (implants, tubing, seals), consumer electronics (protective coatings, adhesives), microfluidics, and laboratory applications where biocompatibility and resistance to thermal cycling are critical. Engineers select PDMS for applications requiring low-temperature flexibility combined with hydrophobic surface properties and minimal leaching, though its relatively low modulus necessitates careful design in load-bearing roles.
