Durlon® HT1000® L316

Durlon® HT1000® L316


Not Resistant  

Premium Durlon Solutions

Durlon® HT1000® consists of phlogopite mica paper impregnated with an inorganic binder at less than half the binder amount found in vermiculite-phyllosilicate filled products.


Thermal Strength

  • The low binder content allows for superior weight retention
  • Phlogopite mica is a non-toxic naturally occurring hydrated silicate of potassium and magnesium with a lamellar and non-fibrous structure
  • Its flexible, elastic and a high tensile strength and can withstand substantial mechanical pressure perpendicular to the lamellar plane
  • Chemically resistant, fireproof, infusible, incombustible, non-flammable and a known alternative to asbestos
  • Ensures high efficient sealing and performance characteristics in extreme temperature applications
