Ceramic Fiber Papers – Super-Flexible Refractory Materials that Can Take the Heat!

UntitledFrom appliance insulation and mold wrap to high-temperature gasketing and refractory backup for thermal management, ceramic fiber paper has countless uses when it comes to high-heat protection. Another fine thermal refractory ceramic fiber product like our blankets and rigid boards, ceramic fiber paper looks like felt but is thicker than true paper. Our ceramic paper goes up to ¼ inch thick! By adding starch and binders to Fiberfrax ceramic fibers, this product becomes exceptionally flexible and strong. Ceramic fiber paper makes for excellent gasketing and sealing material in stoves and ovens as well as use in expansion joints – anywhere a high-heat insulation solution is needed with minimal thickness.

Fiberfrax® Refractory Ceramic Fiber Moldables and Pumpables Fill-In Your High-Heat Gaps

UntitledUsed to repair refractory linings in ovens, furnaces, kilns, boilers, incinerators, etc. in multiple industries, refractory ceramic fiber in the moldable/pumpable format is injectable for ease-of-use and ultra-convenience. With a putty-like consistency, this product is often used in conjunction with ceramic fiber boards or blankets to line high-temperature chambers and process equipment.

The Fiberfrax Specialties family of products includes Fiberfrax moldables, pumpables, caulks, coating cements, and rigidizers.

More about Ceramic Fiber Moldables and Pumpables

Fiberfrax LDS and LDS-AL moldables consist of Fiberfrax ceramic fibers dispersed in a sticky water-based refractory binder. These materials have a putty-like consistency which permits application by caulking, troweling, or hand forming. Both products adhere well to most surfaces. Drying is accomplished at a noncritical, elevated temperature, and the resulting dried material is strong, hard, and erosion resistant. LDS-AL moldable possesses excellent resistance to wetting by many nonferrous molten metals and is used extensively in molten aluminum contact applications.

Fiberfrax Pumpable-LDS, Pumpable-GS, and Topcoat 2600

Insulating Mix were designed for application into difficult-to-reach areas requiring insulation. Fiberfrax Pumpable-LDS and Pumpable-GS have temperature grade ratings of 1260°C (2300°F). Fiberfrax Topcoat 2600 Insulating Mix has a temperature grade rating of 1426°C (2600°F). A conventional air-operated extrusion pump permits application of these products directly from their container into furnace and boiler hot spots, refractory cracks, furnace door jambs, and other areas requiring high-temperature insulation and sealing.

Fibermax caulk is a high-temperature blend of Fiberfrax bulk fibers, Fibermax polycrystalline high-alumina fibers, and inorganic binder. This product is available in convenient-to-use caulking tubes.

DynaGuard™ Microporous Insulating Panels for Convenient Thermal Management

As explained in our blog post about microporous insulating boards, panels made of microporous insulation are basically insulating powder that has been compressed into a rigorous and efficient thermal refractory material for smaller spaces and is then used in high-heat or tight and compact scenarios. The value of our microporous insulation is two-fold.

UntitledFirst, our microporous insulation is a VERY efficient insulating material for high-temperature furnaces, kilns and oven linings. Indeed, microporous insulation is the most efficient insulating material we feature on our website. Secondly, due to the “micro porous” nature of this insulating material, a thinner layer or amount can be used than with ordinary insulation made from ceramic fiber. This is very helpful for certain applications within smaller spaces, and our panels work well to line appliances and smaller thermal units.

More on Microporous Insulation Panels

The extremely low-thermal conductivities of DynaGuard microporous products from Armil CFS save space, weight, and energy for thermal management and convenience. Microporous insulations such as DynaGuard insulating panels provide excellent thermal stability while allowing for consistent operating temperatures.
DynaGuard Panel Insulation Systems represent one of Armil CFS’ microporous products for primary use in industrial and commercial applications. Each DynaGuard panel is a rigid, textile-encased, comparatively dense material with high compression resistance and exceptional strength, and its superior thermal performance allows for the maximum amount of thermal protection to be provided within minimum space and weight requirements.

DynaGuard insulating panel systems are also specially formulated to minimize heat transfer via conduction, convection and radiation through the material by use of the following design and engineering standards:

  • Ceramic powders with intrinsically low thermal conductivity: the microporous core materials used in the manufacture of DynaGuard insulating panel systems possess a thermal conductivity even lower than that of still air, and minimize the solid conduction of energy through the material.
  • Special opacifiers: the introduction of special opacifiers into the DynaGuard Panel formulation ensures that the transmission of infrared radiation through the material is kept to the lowest possible levels.
  • Microporous structure: the microporous structure of the DynaGuard insulating panel system inherently minimizes the possibility for air current convection through the material, as void spaces too small for air currents to exist form between the core material components.

The DynaGuard Panel microporous core material is a 1,800ºF continuous-use formulation, and is compressed into a uniform thickness and density to ensure the proper distribution of the core material. In addition to the microporous core, DynaGuard panels are also supplied encased in a high-temperature textile shell. This shell provides additional structure, strength, ease of handling and installation, and consistent distribution of the core material, and may also be used to increase the overall composite temperature use limit of the assembly as specified by individual customer needs.

DynaGuard™ Panel systems are supplied standard at 17 lbs/ft3 density, 24″x 36,” in thicknesses of 1/2″ to 1-1/2,” and with a fiberglass textile shell (1,000ºF use limit). Other densities, sizes, thicknesses and cloth facings are available upon request here.

DynaGuard Panel Insulation Systems Advantages

Lowest Thermal Conductivity

Because DynaGuard insulating panels inherently possess a thermal conductivity lower than that of still air, even at elevated temperatures, they are ideal in environments where materials with low thermal conductivity, thermal diffusivity and heat storage are necessary.

Space and Weight Savings

Because smaller amounts of DynaGuard Panel are needed for thermal management, it is an ideal material for industrial and commercial applications where considerable space and/or weight savings are valuable in increasing capacity or efficiency without sacrificing the thermal performance of the system.

High Temperature Capability

DynaGuard Panel insulating systems can be manufactured to meet continuous high-temperature environments up to 1,800ºF, but are also capable of performing in intermittent exposure to 2,000ºF temperatures.
