Comparing the Best Rubber Compound for High Temperature Gasket Applications13 October 2020
There are a few rubber gasket compounds for use in raised temperature applications. There are, of course, numerous things to assess before choosing the best possible material. Other than the temperature, the liquid (or media), framework weight, and presentation conditions should be thought of. Those variables will influence the last decision, however this concise outline will highlight temperature limits.
Read on below to compare the best rubber compound for high temperature gasket applications.
For applications where the rubber material won’t be presented to acids, soluble bases, superheated steam (over 250ºF), sweet-smelling hydrocarbons, and certain powers, Silicone is a decent decision for the gasket you will utilizing. Silicone has an unrivalled temperature go, for the most part staying adaptable from – 75ºF to + 450ºF, and is the compound of decision for hot, dry air gasket applications.
Viton®, while not an awesome compound for low temperatures, is a magnificent decision in high temperature gasket applications up to around 400ºF. Viton® has better obstruction than a wide assortment of synthetic compounds, including numerous acids, powers, fragrant hydrocarbons, chlorinated hydrocarbons, and non-combustible water driven liquids. The entirety of the Viton® gaskets we gracefully are produced using certifiable DuPont material; not a nonexclusive FKM.
EPDM is the best rubber gasket material for steam and boiling water applications to 350ºF, with some EPDM materials equipped for taking care of temperatures in steam to 400ºF. EPDM isn’t viable with oil based liquids, yet can deal with numerous Glycol based liquids to 300ºF.
Perfluoroelastomers handle a more extensive scope of synthetics than Viton®, however most usually are accessible just as O-rings. Perfluoroelastomers (the most usually known is Kalrez®) by and large are heat impervious to 600ºF, yet because of their extraordinary cost, and restricted shape and size accessibility, ought to be viewed as just when the application can’t be fixed with another material. At the point when temperatures surpass the cut-off points noted above, it is likely a material other than rubber will be required.
