Silicone Rubber Thermal Expansion Coefficient

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.

Silicone rubber thermal expansion coefficient.

Mse supplies stands behind our promise for h igh quality products with competitive pricing and dependable technical support from phd scientists. The table at. The curing method can be either vulcanized or catalyzed. 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 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. Song in progress in rubber nanocomposites 2017. Our dialometry testing services use netzsch dil 402 pc or similar instrument.

2 chart 2 plastics and other non metals. Temperature expansion thermal expansion of pipes and tubes stainless steel carbon steel copper plastics and more. Silicones are polymers with a si o si backbone. There have been instances where a seal has ruptured a steel gland due to expansion when heated.

These forces are generated by thermal expansion of the rubber and or swelling effect of a fluid. The overall coefficient is the linear thermal expansion in per degree. There are different types depending on functional groups in the structure and curing mechanisms. Main applications are flexible seals o rings etc.

This expansion is an advantage for sealing applications. Coefficient of thermal expansion silicone has a high thermal expansion coefficient and can be used as a temperature activation method or sensor in the design. Material properties material properties for gases fluids and solids densities specific heats viscosities and more. 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.

Generally linear thermal expansion is most applicable to solids. The coefficient of thermal expansion is defined as the change in length or volume of a material for a unit change in temperature. Thermal expansion is usually expressed in one of two ways either volumetric expansion or more commonly linear expansion expressed as a coefficient. Abs pipes pressure ratings pressure ratings of.

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. Choose professional dilatometry and thermal expansion coefficient cte testing services from mse analytical services. Silicone rubber 190 0 x 10 6 342 0 x 10 6 mech. The linear thermal expansion coefficient cte is dependent on the material from which an object is made.
