polydimethylsiloxane

Polydimethylsiloxane (PDMS) is a silicone-based elastomeric polymer composed of alternating silicon and oxygen atoms with methyl side groups, valued for its chemical stability, thermal resilience, and flexibility across a wide temperature range. It is widely used in medical devices (implants, tubing, catheters), consumer products (sealants, coatings, cosmetics), microfluidic devices, and industrial gaskets where biocompatibility, low toxicity, and resistance to thermal and chemical degradation are required. Engineers select PDMS when flexibility, durability in demanding environments, and non-reactivity with biological systems are critical; its silicone backbone provides superior longevity compared to conventional organic polymers in sterilization, UV exposure, and temperature cycling applications.
