HT1000® Sheet

HIGH TEMPERATURE GASKET MATERIAL

Phlogopite Mica with Inorganic Binder
ht1000-cut-gaskets

application:

Durlon® HT1000® ensures efficient sealing and performance characteristics in extreme temperature applications. It is flexible, elastic, has a high tensile strength, can with-stand substantial mechanical pressure perpendicular to the lamellar plane, chemically resistant, fire-proof, infusible, incombustible, non-flammable and is a known alternative to asbestos.

composition:

Durlon® HT1000® consists of phlogopite mica paper impregnated with an inorganic binder at less than half the binder amount found in a typical vermiculite-phyllosilicate filled product. This lower binder content allows for superior weight retention, less than 4% weight loss at 1,472°F (800°C), and results in ultimate extreme temperature sealing performance up to 1,800°F (1,000°C).

available styles:

  • HT1000®-S90 Phlogopite mica paper impregnated with an inorganic binder and no carrier.
  • HT1000®-L316 Phlogopite mica paper impregnated with an inorganic binder laminated with a 0.002” thick stainless steel carrier.
  • HT1000®-T316 Phlogopite mica paper impregnated with an inorganic binder laminated with a 0.004” thick stainless steel perforated carrier.

Warning: Durlon® gasket materials should never be recommended when both the temperature and the pressure are at the maximums listed. Properties and applications shown are typical. No application should be undertaken by anyone without independent study and evaluation for suitability. Never use more than one gasket in one flange joint, and never reuse a gasket. Improper use or gasket selection could cause property damage and/or serious personal injury. The data reported is a compilation of field testing, field service reports and/or in-house testing.
