Silicone Oil Thermal Conductivity

Ss 35 is a thermally conductive silicone rtv transfer adhesive rubber developed for heat sink applications.

Silicone oil thermal conductivity.

To confirm the ht 110 is a pdms silicone oil with a viscosity of 100cst 25c. Ht 110 has a lower vtc value and does not thicken as acutely as the pm 125 dpdm 400 when chilled. It is heat stabilized with an iron siloxane additive and will remain stable at elevated temperatures. At 25 c the densities are 2 40 2 69 and 1 96 g ml for the greases 860 8616 and 8617 respectively.

Ss 35 is a 1 part silicone thermal conductive paste that when applied to the substrate enables adhesion to parts and heat transfer of the bonded assembly within minutes. It has virtually no oil separation or. A silicone oil is any liquid polymerized siloxane with organic side chains. Although thermal conductivity increases with higher viscosities it becomes nearly constant at viscosities above 100 mm 2 s.

The thermal conductivity of dimethyl silicone fluid is lower than that of common organic compounds nearly the same as that of benzene and toluene and is roughly 25 that of water. The thermal conductivity of silicon oil is typically lower than most common organic compounds but close to the values of benzene and toluene and it has roughly on quarter of water s conductivity ca 0 6 w m k 20 c. The most important member is polydimethylsiloxane these polymers are of commercial interest because of their relatively high thermal stability and their lubricating properties. The thermal grease 860 is a silicone oil with a zinc oxide filler and 8616 and 8617 are synthetic oils with various fillers including aluminum oxide and boron nitride.

This combination of high purity fillers and silicone results in a smooth homogeneous white high temperature dielectric compound.
