A few things jump out from that table. The thermal conductivity values \u2014 0.10\u20130.12 W\/m\u00b7K at 400\u00b0C \u2014 are competitive with much thicker insulation products. That’s the nature of the material: even a 3mm sheet provides meaningful thermal resistance. The tensile strength numbers look modest in absolute terms, but for a 3mm paper-form product, they’re actually quite good \u2014 enough to handle without tearing during normal installation.<\/p>\n

Can Ceramic Fiber Paper Be Cut, Formed, and Fabricated?<\/h2>\n

Yes, and this fabricability is genuinely one of its best selling points. Unlike ceramic fiber board, which requires power tools to cut, and unlike ceramic fiber blanket, which frays and sheds fibers if you try to cut it with anything less than a sharp knife, ceramic fiber paper behaves like \u2014 well, like paper. Within reason.<\/p>\n

Hand cutting.<\/strong>\u00a0Sharp scissors or a utility knife cut 1\u20133mm paper cleanly. For 6mm paper, a straightedge and a fresh utility knife blade gives clean edges without tearing.<\/p>\n

Die cutting.<\/strong>\u00a0This is where ceramic fiber paper really shines. Standard steel-rule dies on flatbed cutting presses stamp out gaskets and seals in high volumes with consistent dimensions. The material doesn’t gum up dies, doesn’t require lubrication, and produces clean cut edges with minimal fiber fraying. Most gasket manufacturers who work with high-temperature materials have die-cutting operations set up for ceramic fiber paper.<\/p>\n

Punching.<\/strong>\u00a0Hole punches, both manual and hydraulic, work well for producing bolt holes in gaskets. For high-volume production, custom punch presses turn out hundreds of identical gaskets per hour.<\/p>\n

Forming and wrapping.<\/strong>\u00a0The 1mm and 2mm grades are flexible enough to wrap around cylinders, pipes, and curved surfaces without cracking. Thicker grades can be bent around gentle curves but will crack on tight radii \u2014 try to keep the bend radius above 100mm for 6mm paper.<\/p>\n

Laminating.<\/strong>\u00a0Ceramic fiber paper can be laminated to metallic foil, glass cloth, or other facing materials using high-temperature inorganic adhesives. These composite products add surface protection and improve handleability in applications where the bare paper might abrade or tear during installation.<\/p>\n

How Does Ceramic Fiber Paper Perform as a Gasket Material?<\/h2>\n

Gasket performance comes down to three things: sealing effectiveness under compression, resistance to blowout at operating pressure, and long-term stability so the gasket doesn’t require constant re-torquing. Here’s how ceramic fiber paper stacks up on each count.<\/p>\n

Compression sealing.<\/strong>\u00a0Ceramic fiber paper compresses readily under bolt load, flowing into surface irregularities and microscopic imperfections on flange faces. It doesn’t require high bolt loads to achieve an effective seal \u2014 important when you’re working with thin cast iron or ceramic flanges that can crack under excessive torque.<\/p>\n

Blowout resistance.<\/strong>\u00a0Paper-form ceramic fiber isn’t designed for high-pressure service. In furnace and kiln applications \u2014 which typically operate at slightly negative pressure (draft) or very low positive pressures \u2014 blowout isn’t a concern. If your application involves gauge pressures above about 0.5 bar, you’d want to look at reinforced ceramic fiber sheet or a metal-jacketed gasket instead.<\/p>\n

Long-term stability.<\/strong>\u00a0This is where ceramic fiber paper outperforms organic-binder-based gasketing materials like compressed fiber sheet (CFG). Above 300\u00b0C, CFG oxidizes and hardens, eventually losing its compressibility and allowing flange joint leakage. Ceramic fiber paper, once its organic binder has burned out in the first heat cycle, is purely inorganic and maintains its properties indefinitely at operating temperature \u2014 no oxidation, no carbonization, no hardening.<\/p>\n

\u015eu\u00a0U.S. Department of Energy’s Better Plants program<\/a>\u00a0has identified high-temperature gasket performance as a meaningful factor in industrial energy efficiency, noting that leaking furnace joints can increase energy consumption by 5\u201315% in susceptible equipment types.<\/p>\n

AdTech Real Case: Upgrading a Japanese Ceramic Kiln Manufacturer’s Production Line<\/h2>\n

In mid-2024, a specialty ceramics manufacturer based in Aichi Prefecture, Japan, approached AdTech with a specific and somewhat unusual problem. The company produced fine technical ceramics \u2014 alumina substrates, zirconia components, and silicon carbide structural parts \u2014 in a line of continuous pusher kilns running at peak temperatures of 1400\u00b0C.<\/p>\n

Their existing interlayer insulation between kiln furniture components was a domestic fiberglass paper product rated to 700\u00b0C. During a routine process audit, their quality engineer noticed that the fiberglass paper was completely disintegrating above the transition zone in their kilns, where temperatures exceeded 800\u00b0C. Fragments of degraded fiberglass were contaminating the kiln atmosphere and, in some cases, adhering to the surfaces of sintered ceramic components \u2014 which caused rejection rates in their high-purity alumina substrate line to spike from a baseline of 2.3% to over 7% during certain production runs.<\/p>\n

The contamination source wasn’t immediately obvious \u2014 the failed fiberglass paper fragments were small and only showed up under microscopic surface inspection. It took their quality team three months to trace the rejects back to the kiln furniture insulation.<\/p>\n

AdTech recommended our\u00a0HA-grade ceramic fiber paper (1400\u00b0C classification, 3mm thickness, 160 kg\/m\u00b3 density)<\/strong>. The high-alumina grade was specified \u2014 rather than standard HP-grade \u2014 because the kiln peak temperature of 1400\u00b0C left very little safety margin for the HP grade. The low iron content of our HA paper (Fe\u2082O\u2083 under 0.3%) was also critical, since iron contamination is particularly damaging in alumina substrate sintering.<\/p>\n

The customer ordered an initial trial quantity of\u00a02,400 square meters<\/strong>\u00a0in 300mm \u00d7 600mm pre-cut sheets, sized to match their kiln furniture dimensions and minimize on-site waste. AdTech also supplied a small quantity of 1mm HA-grade paper for use as slip sheets between stacked components in their shuttle kilns.<\/p>\n
