1 Product Information Sheet Fiberfrax Ceramic Fiber Introduction Fiberfrax ceramic fibers are a family of high-temperature fibers designed to be used in a variety of industrial and commercial applications. Manufactured from alumina-silica materials, Fiberfrax fibers are chemically inert. Some of the unique properties these fibers offer are: High-temperature stability Low thermal conductivity Low heat storage Excellent thermal shock resistance Lightweight Fiberfrax fibers are available in a variety of chemistries and diameters which can service a wide variety of applications. In addition, these fibers can be further modified by chopping or by removal of the unfiberized particles (called shot). Lubricants can also be added to the fiber to enhance fiber properties. Fiberfrax fibers exhibit excellent chemical stability and resistance to attack from most corrosive agents. Exceptions include hydrofluoric acid, phosphoric acid and strong alkalis. Fiberfrax fibers also effectively resist oxidation and reduction. If wet by water or steam, thermal and physical properties are restored upon drying. Fiberfrax fibers contain no water of hydration. Fiberfrax Bulk Fibers Fiberfrax Bulk Fibers are manufactured to be used as feedstock in manufacturing processes or other applications where product consistency is critical. Manufactured on large, computer-controlled furnaces, these products provide customers with consistent material properties. Fiberfrax Bulk Fibers are typically used in the manufacture of other ceramic fiber based product forms such as: High-temperature boards, felts, and papers Combustion chambers for commercial and residential boilers Riser sleeves for molten metal casting Fireplace logs and panels for gas fireplaces Tap out cones for molten metal applications Specialized vacuum-formed shapes These bulk fibers can also be directly used as hightemperature fill and packing material in a variety of hightemperature applications, such as: Expansion joints Furnace base seals Tube seals Burner tile packing Chimney insulation Fiberfrax 7000 Series Fiber Fiberfrax 7000 Series fibers are manufactured from highpurity alumina-silica materials for use in applications up to 2300 F (1260 C). These products are manufactured on computer-controlled, state-of-the-art furnaces to provide customers with consistent fiber properties. Fiberfrax 7000 Series fibers can also be chopped into several grades (coarse, medium, and fine) to provide customers with a fiber ideally suited for their application. Benefits of Fiberfrax 7000 Series fibers include: Low thermal shrinkage at high temperatures Consistent fiber properties Several chopped grades Fiberfrax 6000 Series Fiberfrax 6000 Series fibers have many of the same properties as the 7000 Series fibers. The main difference is that 6000 Series fibers are manufactured from kaolin clay rather than high-purity alumina-silica raw materials. Since kaolin is a mined material, it may contain impurities such as Fe 2 O 3, TiO 2, and Na 2 O as listed in the chemical composition chart on page 2. Even with these impurities, Fiberfrax 6000 Series fibers can provide an effective solution in many vacuum-forming and related applications. Refer to the product Material Safety Data Sheet (MSDS) for recommended work practices and other product safety information.

3 Fiberfrax Specialty Fibers In addition to Fiberfrax Bulk Fibers, Unifrax has the ability to produce many different specialty fibers that provide a variety of desirable performance properties for certain applications. These fibers can be classified into the following general categories: High-Index Fibers High-Temperature Fibers Large-Diameter Fibers Milled Fibers High-Index Fibers Fiber index is a measurement which determines the amount of fiberized material in the actual fiber. During fiber manufacturing, shot or unfiberized material is produced as a natural product of the fiberization process. Unifrax has the ability to reduce the amount of shot in a fiber by controlling the furnacing process or by washing out the unfiberized material. As shown in the table on page 4, Unifrax offers several high-index fibers ranging in fiber index from 68% up 95+%. Fiberfrax High-Index Fibers have proven to be a good reinforcement material for use in automotive brake lining and other friction materials. These high-index fibers provide a variety of desirable properties such as: Frictional stability High-temperature frictional performance Fade resistance Flexural reinforcement Fiberfrax High-Index fibers can also be used as a mechanical thixotrope in coatings applications offering reinforcement and fire resistance as additional benefits. These fibers offer the following unique properties: Excellent high-temperature stability Good strength and high modulus Low coefficient of thermal expansion Superior chemical resistance Very low moisture absorption The thixotropic properties of Fiberfrax High-Index Fibers in conjunction with the mechanical and physical properties they have to offer make them an excellent candidate for use in: Mastics Adhesives Thick Film Coatings Fire Protective Materials Caulks, Putties, and Sealants Fiberfrax High-Temperature Fibers Unifrax manufactures two high-temperature specialty fibers for use in applications beyond recommended operating temperatures of 2300 F (1260 C). Bulk 8000 is made from high- purity alumina, zirconia, and silica raw materials. This chemistry, along with the unique manufacturing process, provides a fiber which can with stand continuous operating temperatures up to 2450 F (1345 C). Fibermax Bulk Fiber is a high-temperature, polycrystalline mullite fiber. Fibermax fiber can withstand continuous operating temperatures up to 2800 F (1540 C) and is virtually shot free. Fibermax fibers can be blended with regular aluminasilicate Fiberfrax fibers to increase the thermal stability of the blended product beyond that of high-purity bulk fiber. Fiberfrax Large-Diameter Fibers Unifrax has the ability to control the average fiber diameter of fibers through a unique spinning operation. It is this spinning operation that is used to produce both the Fiberfrax Spun Fiber and Long Staple Fibers. Average fiber diameters for these fibers range from 3 to 12 microns as detailed on the table below. These larger-diameter fibers provide certain desirable properties, such as: Excellent resistance to mechanical stress and vibration Reduced processing time in vacuum-forming operations Ability to produce lower-density vacuum-formed products Fiberfrax Milled Fibers Fiberfrax Milled Fibers are ball milled from Regular Fiberfrax Fibers to reduce fiber length, thus increasing the flowability and facilitating its dispersion in a matrix, such as resins or refractory cement compositions. Fiberfrax Milled Fibers can also be used as a compact filler insulation. These milled fibers can be used as a functional additive in a variety of coatings and composites to provide the following benefits: Superior wear resistance Improved corrosion resistance Provides reinforcement and excellent compressive strength Form C-1420 Effective 5/ Unifrax I LLC All Rights Reserved Printed in USA Page 3 of 4

7 Product Information Sheet Fiberfrax Blanket and Mat Products Introduction The Fiberfrax blanket and mat product family is a group of lightweight, thermally efficient ceramic fiber insulating materials that combine the advantages of dimensional stability at high temperatures with complete resistance to thermal shock. Featuring a broad range of thermal capabilities and physical characteristics, this product family provides proven and effective solutions to a variety of heat processing applications. Durablanket ceramic fiber products are high strength, needled insulating blankets that are made from spun Fiberfrax ceramic fibers. The extra-long spun fibers, crosslocked through a unique forming process, produce a blanket with exceptional handling strength. The Durablanket product family is completely inorganic and available in a variety of temperature grades, densities, and sizes. Fibermat Mat, PH blanket, and Moist Pak-D insulation provide additional options for specific application requirements ranging from high-temperature filtration to hot gas velocity resistance. Fibermax Mat is a high-temperature, flexible mat product entirely composed of Fibermax polycrystalline mullite fibers, making it an extremely lightweight, highly resilient insulator that is virtually free of unfiberized ( shot ) particles. Having excellent chemical stability, Fiberfrax blanket and mat products are unaffected by most chemicals except hydrofluoric and phosphoric acids and concentrated alkalies. If wet by water or steam, thermal and physical properties remain unaffected after drying. Durablanket S Fiberfrax Durablanket S insulation is a strong, lightweight, flexible needled blanket that is made from spun ceramic fibers. Available in a wide variety of thicknesses, widths and densities, Durablanket S insulation provides an array of proven solutions for a broad spectrum of application problems. Durablanket HP-S Fiberfrax Durablanket HP-S insulation is a needled blanket made from spun Fiberfrax ceramic fibers. Durablanket HP-S insulation combines all of the physical characteristics offered by Durablanket S insulation in a product with a high-purity chemistry.

8 Duraback Fiberfrax Duraback blanket is a strong, lightweight, flexible needled blanket intended for use as a cost-effective back-up insulation in Fiberwall furnace linings. It is recommended for use up to 982 C (1800 F). Duraback blanket can be installed up to four times faster than common block-type back-up insulation. Fibermat Blanket Fiberfrax Fibermat is a lightweight, high-strength needled insulating blanket. The blanket fibers are spun from a ceramic composition having a normal use limit of 760 C (1400 F). Fibermat is completely inorganic and derives its exceptional strength from the needling of long ceramic fibers. It has excellent thermal and acoustical insulating properties. PH Blanket Fiberfrax PH blanket is a unique product that has been specifically designed to provide excellent filtration capabilities in addition to the high chemical stability and low thermal conductivity that is possessed by all Fiberfrax products. PH blanket is made from Fiberfrax bulk ceramic fibers in a unique wet felting process which removes unfiberized particles. In addition to the strength and resiliency afforded by the interlocking of fibers during the manufacturing process, handling strength is further enhanced by the addition of a small amount of organic binder. A typical filtration application would involve utilizing PH blanket as a platinum catalyst recovery filter in nitric acid production. In this application, PH blanket offers numerous advantages over glass wool products including longer life, 50-60% improved filter efficiency, reduced chance of blowouts, and better temperature resistance. Moist Pak-D Fiberfrax Moist Pak-D insulation is made from high-strength ceramic fiber blankets impregnated with inorganic bonding agents. This processing results in a flexible insulation that air dries to form a hard, rigid structure. Moist Pak-D is ideal for insulation of complex shapes and for service under conditions of high hot gas velocities. The material is packaged in a clear polyethylene bag to retain the wet binder during shipment and storage. Since damage will occur, care should be taken to prevent freezing of the product. Curing of product can be accomplished by air drying for several days or by immediate exposure to temperature in the application. Curing is merely a function of removing the water from the inorganic binder. Fibermax Mat Fibermax Mat is a high-temperature, flexible mat product that is lightweight (1.5 Ib/ft 3 density) and highly resilient. It is composed entirely of Fibermax polycrystalline mullite fibers to produce a product that is high-temperature (1650 C/3000 F) resistant and virtually shot-free. Fibermax Mat contains no organic binders or other additives which cause outgassing fumes or associated problems. In addi tion to exhibiting excellent resistance to attack from most corro sive agents (exceptions include hydrofluoric acid, phosphoric acid and strong alkalies), Fibermax fiber also resists oxidation and reduction.

15 Product Information Sheet Fiberfrax Duraboard Products Introduction Fiberfrax Duraboard products are a family of rigid, hightemperature ceramic fiber boards manufactured in a wet forming process using Fiberfrax alumina-silica fibers and binders. All Duraboard products offer low thermal conductivity, high temperature stability, uniform density, and excellent resistance to thermal shock and chemical attack. They are also well-suited for applications experiencing vibration, mechanical stress and strong erosive forces. The excellent rigidity and modulus of rupture possessed by these boards makes them strong and self-supporting, yet relatively lightweight and easy to cut or machine. These product features allow for quick, efficient handling and high installation rates, thereby enabling fast turnaround times in a variety of industrial insulation applications. Once installed, they can help reduce energy costs and cycling times due to their high insulating capability, as well as serving to protect refractory surfaces from thermal shock. The Fiberfrax Duraboard family exhibits excellent chemical stability, resisting attack by most corrosive agents. Exceptions are hydrofluoric, phosphoric, hydrochloric and sulfuric acids as well as concentrated alkalies. Fiberfrax Duraboard products also resist oxidation and reduction. If wet by water, steam or oil, thermal and physical properties are completely restored upon drying. In order to provide handling strength during the manufacturing process, small quantities of organic and inorganic binders are typically added to the board formulation. Where present, the organic binding agents burn out at temperatures between 450 F/232 C to 600 F/316 C during initial heat up by the end user. Following burnout of the organic binder, the boards are white in color.

16 Duraboard Products Duraboard RG Duraboard RG (Refractory Grade) insulation is a cost-effective insulating board manufactured with the specific requirements of the refractory industry in mind. It has a rolled, rigidized surface which gives it a high modulus of rupture and compressive strength as well as high abrasion and hot gas erosion resistance. These properties make Duraboard RG insulation ideally suited for use both as a backup to dense refractories, such as those used in the glass industry, and as a hot face protective layer over blanket linings where the rigidized surface aids in dust suppression during both installation and operation. Duraboard LD This product possesses the same density and temperature rating as Duraboard RG insulation, but is manufactured to tighter dimensional tolerances and has an excellent finished surface. These characteristics make it ideally suited for use as a sandwich or core material or for use in the manufacture of components where aesthetic quality, as well as uniformity and performance, is important. It is available in a variety of standard thicknesses ranging from =z to 2z. Duraboard HD Duraboard HD insulation is a high-density board product that offers the same high level of dimensional and surface uniformity as Duraboard LD insulation, but provides enhanced compressive strength and a higher modulus of rupture. This higher density is achieved through the inclusion of clay additives during the manufacturing process. Its higher strength makes Duraboard HD insulation particularly well-suited to weight load support applications such as refractory brick backup or for covering larger unsupported spans. Duraboard 350ES and 500ES These products use a unique fiber formulation to obtain high strength and machinability not normally achieved in lightweight ceramic fiber board products. The innovative composite binder system using both inorganic and organic components results in a strength-to-weight ratio of more than three times that of standard refractory ceramic fiber boards. Improved physical characteristics of these products allow for easier handling and fabrication. Duraboard 350ES has more than three times the strength of standard boards of similar densities and thicknesses. Duraboard 500ES has more than four times the strength of standard boards of similar densities and thicknesses. Duraboard 2600 Duraboard 2600 insulation is a high-temperature insulating board designed to provide high stability at elevated temperatures. This capability is achieved by manufacturing a board formulated with a blend of Fiberfrax alumina-silica fibers and Fibermax, Unifraxʼs patented polycrystalline mullite fibers. This unique formulation controls thermal shrinkage to a level less than 1.0% after 168 hours at 2450 F/1343 C. Duraboard 3000 Duraboard 3000 insulation, the highest temperature rated board manufactured by Unifrax, provides maximum high-temperature stability and shrinkage resistance. Also formulated from a blend of Fiberfrax alumina-silica fibers and Fibermax, Unifraxʼs patented polycrystalline mullite fibers, Duraboard 3000 insulation derives its exceptional high-temperature capability from an increased Fibermax fiber concentration in the blend. This unique formulation controls shrinkage to a level of only 1.2% after 168 hours at 2700 F/1482 C. Inorganic Boards Duraboard products are manufactured using a combination of both organic and inorganic binding agents. In certain applications, the presence of organic binders and the low temperature burnout that is associated with them may be unacceptable. These products may be ordered with the organic binding agents already removed by heat treating following the manufacturing process. Heat treated boards display a reduced modulus of rupture and an increase in dustiness.
