Ceramic Fiber

Ceramic Fiber is an excellent source of heat insulation for low to high heat temperature applications.  NUTEC produces MaxWool Spun Ceramic Wool Blanket, Supermag Low Bio-Persistent Products, MaxBlok Modules, MaxBoard and all other types of ceramic based fiber products.  We also have the potential to create custom vacuum formed shapes which can be molded to specific specifications depending on customer need.  These products are used in the Steel, Refining, Chemical and Ceramic industries to provide backup linings to other refractories including fire brick and monolithics. 


MaxWool™ Ceramic Fiber Blanket is composed of long flexible, interwoven fibers manufactured by the “spun” process yielding a strong, lightweight, durable product. This material can be used for applications with temperatures from 1000°F (538°C) to 2600°F (1425°C). MaxWool™ Blankets have high tensile strength for longer life and durability. MaxWool™ Ceramic Fiber Blankets contain no binders and are completely inorganic.


Nutec™ Supermag is a high temperature body low bio-persistence fiber that utilizes a unique spinning technology to create a special fiber with superior thermal and mechanical properties. This fiber is made from a blend of calcium, silica and magnesium and can be exposed to temperatures up to 2192°F (1200°C).  Nutec™ Supermag products are produced in our ISO-9001: 2008 certified facility where bulk, double needled blanket and modules are manufactured. The Nutec™ Supermag family of products can be used in a variety of applications including refractory linings, thermal insulation, and fire protection.


MaxBlok™ Modules full thickness furnace linings and provide a high quality insulation system. Each Module is continuously folded and compressed to specific density to provide longer furnace life. MaxBlok™ Modules linings provide low heat loss and storage which increases furnace productivity and efficiency.


MaxBoard™ products are processed from alumina and silica blends for applications with temperatures up to 3000°F (1650°C). MaxBoard™ are vacuum formed products that are made to resist high velocities. These products proved low thermal conductivity, low heat loss and heat storage. Vacuum Formed Boards are ideal for furnace linings, boiler ducts and stacks. MaxBoard™ can be made with Organic or Inorganic (no smoke) formulations to meet your product requirements.


MG-1900 Board is a low-cost, high strength insulating board manufactured with the specific requirements of the refractory industry in mind. Made from a blend of Soluble Fibers and other fillers, MG-1900 Board offers an effective solution compared to other mineral wool products used for similar applications, but with enhanced advantages offered by low bio-persistent fibers (LBP).  MG-1900 Board is ideal for refractory back-up applications comes standard with a water repellent coating as an added protection if installed behind refractory castables.


MaxPly™ Paper is a lightweight refractory material processed from a blend of high purity alumina-silica wools. This product can be used for applications for continuous use to temperatures of 2300°F (1260°C). MaxPly™ Paper has a good handling strength, low thermal conductivity and low shrinkage. It contains an organic binder which makes it flexible and reduces off-gassing and odor during use. The paper has highly uniform consistency due to its controlled basis weight and thickness. This product is ideal to gaskets and seals. MaxPly™ Paper is durable and can be cut with a knife, shears, or standard steel rule dies. Its flexibility allows it to be wrapped or rolled to fit around most configurations. MaxPly™ Paper is free of asbestos and is designed to be a replacement for asbestos paper in most applications.
