Polydimethylsiloxane (PDMS)

polymer

Polydimethylsiloxane (PDMS) is a silicone-based synthetic polymer characterized by a silicon-oxygen backbone with methyl side groups, making it chemically distinct from carbon-chain polymers. It is widely used in industries requiring materials with low surface energy, high flexibility, and thermal stability—including medical devices (implants, contact lenses), consumer products (sealants, coatings), microfluidics research, and elastomer applications. PDMS is valued for its biocompatibility, gas permeability, and resistance to temperature extremes and UV exposure, making it a preferred choice where conventional plastics would degrade or where surface properties need tight control.

Safety & Biocompatibility

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
