Insulfrax® Paper

Insulfrax® Paper is an evolutionary product which is manufactured by forming Insulfrax Fiber in a non-woven matrix. These fibers are randomly oriented during manufacturing and then held in place with a latex binder system. A specialized paper-making process is utilized to form uniform lightweight, flexible materials, including Insulfrax Paper.

Typical applications:

  • Automotive and aerospace heat shields
  • Gaskets for ovens, stoves, heaters, and other appliances
  • Nonferrous ingot mold liners
  • Refractory backup insulation in ladles, glass tanks, and other high-temperature furnaces
  • Parting medium in brazing and soldering
  • Molten aluminum transfer systems

Insulfrax Fiber, utilized in Insulfrax Paper, is a low bio-persistent line of products based upon a calcium, magnesium, silicate (CMS) chemistry. This CMS fiber chemistry has been successfully used to solve a variety of application problems from 427°C (800°F) up to 1100°C (2012°F). In addition to high temperature resistance, Insulfrax Fiber meets European regulatory requirements (Directive 97/69/EC).

Insulfrax Paper offers many unique problem-solving advantages, which include: high-temperature stability up to 1100°C (2012°F), meets European regulatory requirements, superior wetting resistance to molten aluminum, low thermal conductivity, flexibility, and easy to wrap, shape or cut.
