Duocel High Heat Foam

What are foam high temperature filters?

Foam high temperature filters are made of high heat foam such as carbon or silicon carbide. Filters are available in nearly any size or shape and are designed to work at extreme temperatures. We are able to filter molten metals and other high temperature liquids.

Why would you use Duocel® foam high heat foam?

Duocel® silicon carbide foam is routinely utilized in high temperature filter applications that exceed the temperature of our conventional metal and ceramic foams. The corrosive resistance of the material also makes it attractive for use in harsh environments.

Who uses Duocel® foam high temperature filters?

Duocel® Foam high temperature filters can be used to filter molten metal before casting, as a filter cap to protect high temperature sensors from debris and particles, and in PVD chambers to act as a barrier between the plasma generating top and bottom of the chamber.  High heat foam is useful in a variety of  wet or dry applications.
