Fiberfrax® Durablanket® LT and Durablanket LT Z

Fiberfrax® Durablanket® LT and Durablanket LT Z Blankets represent the next generation of the well established Durablanket product family. They offer the same benefits as previous Fiberfrax blankets, now with physical properties enhanced to improve  thermal performance, improved handling and increased strength. These needled blankets combine innovative proprietary technology with proven performance to create high performance RCF blanket products.

Product properties:

  • Excellent handling strength
  • Excellent hot strength
  • Superior thermal conductivity
  • Low heat storage
  • Light weight
  • Resiliency
  • Thermal shock resistance
  • High heat reflectance
  • Excellent corrosion resistance
  • Excellent thermal stability
  • Brand printing on the blanket surface

The enhanced Durablanket LT and LT Z fiber performance helps companies reduce their energy costs and meet increasingly strict carbon emission targets, without increasing the amount of insulation required. Alternatively, customers can save on material costs by using less insulation to achieve the same performance as standard RCF blankets. Customers can save money by reducing their lining thickness up to 25%, freeing up valuable space in furnaces and ovens.

Application Story

Fiberfrax® Anchor‑Loc® LTZ and Fiberfrax® Durablanket® LT

When designing the insulation lining for an ethylene cracking furnace, it is of the utmost importance that it complies with the codes and standards as outlined by the American Petroleum Institute (API). In this application story Unifrax demonstrates the use of ethylene cracker furnace lining systems without the need for a microporous back-up option (RCF modules with microporous back-up board).
