HIGH TEMPERATURE POTTING AND CASTABLE CERAMICS

 

Accumet Materials’ REFRACTOCAST ceramics are ideal for potting, encapsulating or casting applications where high temperature resistance is required.  REFRACTOCAST materials exhibit high thermal conductivity, good dielectric strength and excellent chemical resistance to 3200 ºF.

 

Applications include potting electronic components when it is important to remove heat and hold components in alignment as well as sensor applications, temperature probes, igniters, high power resistors and accelerometers.  In addition, REFRACTOCAST is used as furnace components, brazing and heat treating fixtures, molds and tooling.

 

Accumet’s high temperature materials are easy to use.  After a simple air dry for 1-2 hours and a low temperature cure at 200 - 500°F, these materials are ready to use. REFRACTOCAST contains no volatile organic compounds, are non-flammable and environmentally safe.

 

• REFRACTOCAST ALC is a coarse grain aluminum oxide ceramic used for casting relatively large structures or potting large sections where good thermal conductivity and strength are needed to temperatures up to 3000 ºF.   REFRACTOCAST ALC is strong and offers good chemical resistance. Applications include producing brazing and heat treating fixtures, insulation liners, tooling and furnace components.

 

• REFRACTOCAST ALF consists mostly of fine grain aluminum oxide ideal for use in potting small sections or casting small parts where fine detail is required.  It exhibits high thermal conductivity and good dielectric strength to 3000 ºF. Applications include potting sensors, electrical feed thrus, thermocouples; temperature probes vacuum components and halogen fixtures.
