Dynasheild Ceramic Fiber Blanket is a strong, lightweight needled blanket.  It is made from long ceramic fibers cross locked through a unique forming process which results in excellent strength.  Dynasheild Ceramic Fiber Blankets offer superior flame and heat resisting properties.  The fibers are asbestos free and have a melting point of 1843°C (3350°F).


Dynasheild Ceramic Fiber Blankets are manufactured in various densities, operating temperature ranges and are fabricated into Fire Retarding expansion joint fillers and penetration seals.  DynaShield is noncombustible and is being used in fire retarding systems where lightweight thin materials are needed to obtain a significant temperature drop and fire retardation such as nuclear power plants, utilities, chemical plants and commercial buildings.
