Liquid Silicone Rubber Thermal Conductivity

Silicone rubber unfilled 0 2 glass 1 1 stainless steel 15 aluminium 220 table 1 thermal conductivity of common substances as can be seen a typical unfilled silicone rubber has a thermal conductivity of approximately 0 2 w m k and even a highly filled silicone elastomer can barely exceed 0 4 w m k.

Liquid silicone rubber thermal conductivity.

New carbon materials 2020 35 1. 2 2 4 silicone rubber sir silicone rubber sir is an elastomer composed of silicone containing silicon carbon hydrogen and oxygen in the form of a polymer. Song in progress in rubber nanocomposites 2017. Jia long lin et al.

The curing method can be either vulcanized or catalyzed. Silicone rubbers are often one or two part polymers and may contain fillers to improve properties or reduce cost. Thermal conductivity 9 flame retardancy 9 electrical conductivity 9 compression set 10 flex fatigue resistance 10 tear strength and tensile strength 11. For many years the.

By infusing rubber silicone with carbon black a small amount of conductivity can be imparted into the material while still retaining its superior physical properties. 4 thermal conductivity of neat silicone rubber and its composites the measurement results of the thermal conductivity of neat silicone rubber and its composites were plotted in fig. There are different types depending on functional groups in the structure and curing mechanisms. Although thermal conductivity increases with higher viscosities it becomes nearly constant at viscosities above 100 mm 2 s.

November 1 2001 clemens j. 4 as a function of the weight fraction of the fillers. Lasance articles design materials compounds adhesives substrates test measurement elastomer rubber technical data thermal conductivity in the may 2001 issue this column discussed the thermal conductivity of unfilled plastics. Silicones are polymers with a si o si backbone.

Main applications are flexible seals o rings etc. The thermal conductivity of silicone rubber is higher in comparison with common organic rubbers. Key properties include thermal stability chemical stability electrical insulation and low toxicity. Carbon infused silicone rubber is preferred to meta filled organic rubber because of overall better mechanical performance.

Untreated silicone in gel or liquid form will convert to solid after curing. Silicone rubber is an elastomer rubber like material composed of silicone itself a polymer containing silicon together with carbon hydrogen and oxygen silicone rubbers are widely used in industry and there are multiple formulations.
