One of the few known materials that both draw heat away from hot spots and block electrical currents, aluminum nitride ceramic sheets are great for heat sinks and other electronic components.

Pressed into ultra-dense sheets, these silicon-nitride ceramic sheets resist deforming, expanding, or cracking when compressed, bent, or exposed to quick temperature changes. They’re just as strong and fracture resistant as zirconia ceramic, and hold their strength and shape at higher temperatures.

Drill and mill precisely shaped heat sinks and other electronic components that require thermal stability.

Also known as Macor, these glass-mica ceramic sheets and bars withstand temperatures up to 1470° F.

Made of high-strength calcium silicate, these durable sheets withstand high temperatures and are often used in power-generating applications.

Thinner than most rigid insulation for furnaces and other high-heat applications, these millboard sheets are also used for gasket fabrication.

Typically used in ovens and furnaces, these are the most efficient of our rigid high-temperature insulation sheets. Please note that they require special care when installing since the crumbly material is difficult to work with and will crack easily. Sheets lose strength over time and are intended to be installed behind another facing or insulation material.

Stronger than standard firebricks but with lower insulation capabilities, these withstand heavy abrasion on the floors and sides of furnaces. Also known as hard firebricks.
