X-MAT has announced the release of X-FOAM, a 1,300°C ceramic foam engineered for use in harsh environments demanding high thermal insulation and structural performance. This machinable ceramic foam has a thermal conductivity of only 0.034 W/m·K, on par with some aerogel products; but is stiff and hard, with a compressive strength in the hundreds to thousands of PSI. It is also very light, with a density of only 0.15g/cc, seven times less dense than water. Orlando, FL (SPX) Dec 01, 2025
X-MAT has announced the release of X-FOAM, a 1,300°C ceramic foam engineered for use in harsh environments demanding high thermal insulation and structural performance. This machinable ceramic foam has a thermal conductivity of only 0.034 W/m·K, on par with some aerogel products; but is stiff and hard, with a compressive strength in the hundreds to thousands of PSI. It is also very light, with a density of only 0.15g/cc, seven times less dense than water.
X-FOAM, produced in the United States, is based on X-MAT's silicon oxycarbide polymer-derived ceramic resin. The manufacturing process yields a foam structure that is both lightweight and strong, offering high insulation from cryogenic to re-entry temperatures in air. The material can be machined in its final form with hand tools, bench tools, or CNC machines, and holds a sharp edge.
"This is a major step forward for high-temperature applications," said Josh McConkey, Commercialization Lead. "X-Foam delivers the strength and heat resistance demanded by aerospace and advanced engineering industries, but at a fraction of the weight and cost of existing materials. It's tough, lightweight, machinable, vacuum-stable, and built to perform where other materials fail. Custom versions of X-FOAM can be made radar absorbent, waterproof, or even function for many hours above 1,650°C."
Applications for X-FOAM include aerospace insulation, molten metal filtering, hot gas filtration, furnace and pyrolysis insulation, and oven furniture.
"X-MAT is always reimagining high-performance materials," said Bill Easter, CEO of X-MAT. "With X-Foam we're seeing what's possible when innovation meets real-world needs - a ceramic foam material that's not only high-performing but also highly practical. This product has the potential to redefine insulation, protection and performance in some of the harshest environments imaginable.
