ELEMENT14 PDMS 200 (SILICONE 200/200)

Element14* PDMS series The Element14 PDMS fluids series is a portfolio of products globally available from Momentive Performance Materials. In their chemical structure our Element14 PDMS fluids are quite different from other synthetic materials. The products of the Element14 PDMS line belong to the class of the methyl terminated polydimethylsiloxane polymers. Where organic hydrocarbon fluids are based on a backbone of carbon-tocarbon bonded chains, silicones have an inorganic backbone of alternating silicon-to-oxygen linkages. General chemical structure is shown below, where the variable x denotes the polymerization degree:

Element14 PDMS The silicon-to-oxygen bond is much stronger than the carbonto-carbon bond. Additionally, the inorganic backbone - inherited from quartz – is saturated with organic methyl groups. As a result of this structure silicones exhibit:

• Unusually low viscosities at high molecular weight
• Excellent low temperature fluidity
• Outstanding high and low temperature stability
• Low vapor pressure
• Oxidation stability
• Chemical stability
• Very low interfacial tensions of down to ~20mN∙m-1

As a result of these properties, Element14 PDMS fluids are used in many applications, e.g. as:

• Heat transfer media
• Hydraulic Fluids
• Liquid dielectrics
• Water repellents
• Polish ingredients
• Mold release agents
• Lubricants
• Antifoams
• Damping fluids
• Slipping Acids
