Silicone Rubber Thermal Expansion Coefficient

Material properties material properties for gases fluids and solids densities specific heats viscosities and more.

Silicone rubber thermal expansion coefficient.

The table at. 2 chart 2 plastics and other non metals. Key properties include thermal stability chemical stability electrical insulation and low toxicity. Generally linear thermal expansion is most applicable to solids.

For example silicone may expand linearly 5 9e 4 to 7 9e 4 in in c compared to aluminum at 23 0e 6 in in c or steel at 10 8e 6 in in c. Mse supplies stands behind our promise for h igh quality products with competitive pricing and dependable technical support from phd scientists. Our dialometry testing services use netzsch dil 402 pc or similar instrument. Silicone rubber 190 0 x 10 6 342 0 x 10 6 mech.

Find linear thermal expansion coefficient α and volumetric coefficient for thermal expansion β at 20 c for rubber or for different material like brass copper concrete lead silver water and more. Main applications are flexible seals o rings etc. Thermodynamics effects of work heat and energy on systems. If the seal is completely confined and the gland is 100 filled the dominating force is the force of thermal expansion of the rubber.

Carbons 1 2 to 2 5 x 10 6 2 16 to 4 5 x 10 6. The coefficient of volumetric thermal expansion for all silicone rubber products is in the range of 5 9 to 7 9 x 10 4 4 c. Untreated silicone in gel or liquid form will convert to solid after curing. Thermal expansion is usually expressed in one of two ways either volumetric expansion or more commonly linear expansion expressed as a coefficient.

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. There have been instances where a seal has ruptured a steel gland due to expansion when heated. This expansion is an advantage for sealing applications. Silicones are polymers with a si o si backbone.

Abs pipes pressure ratings pressure ratings of. Choose professional dilatometry and thermal expansion coefficient cte testing services from mse analytical services. Song in progress in rubber nanocomposites 2017. These forces are generated by thermal expansion of the rubber and or swelling effect of a fluid.

The coefficient of thermal expansion is defined as the change in length or volume of a material for a unit change in temperature. There are different types depending on functional groups in the structure and curing mechanisms. The cte employs reciprocal temperature units k 1 f 1 c 1 etc representing the length change per degree per unit length e g in in f or mm mm c. The curing method can be either vulcanized or catalyzed.

The overall coefficient is the linear thermal expansion in per degree.
