Polydimethylsiloxane (PDMS)

PDMS Polydimethylsiloxane​

PDMS Polydimethylsiloxane belongs to a group of polymeric organosilicon compounds that are referred to as silicones. PDMS is the most widely used silicon-based organic-polymer and is particularly known for its unusual rheological or flow properties. PDMS is optically clear and inert, non-toxic, and non-flammable. It is one of several types of  silicone oil (polymerized siloxane). 

Main applications:

  • Component of defoamers
  • Ingredient in water-repellent coatings
  • Plasticizer in silicone sealants
  • Stamp resin in the procedure of soft-lithography
  • Lubricant in condoms
  • A component in silicone grease
  • A component in heat-transfer fluids
  • A component in mold-release agents
  • Sorbent for the analysis of head-space

    Packaging & Shelf Life:
  • 200 kg drum
  • 950 kg & 1000 kg IBC
  • Iso-tanker

    Under proper storage conditions, the shelf life is 24 months.
