HT1000® (Ultimate Mica Technology)

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. This lower binder content allows for superior weight retention, less than 4% weight loss at 800°C (1,472°F), and results in ultimate extreme temperature sealing performance up to 1,000°C (1,800°F).

Phlogopite mica is a non-toxic naturally occurring hydrated silicate of potassium and magnesium with a lamellar and non-fibrous structure. It is flexible, elastic, has a high tensile strength, can withstand substantial mechanical pressure perpendicular to the lamellar plane, chemically resistant, fireproof, in-fusible, incombustible, non-flammable and is a known alternative to asbestos. Durlon® HT1000® ensures efficient sealing and performance characteristics in extreme temperature applications.

Durlon® HT1000® Paste, a high-temperature form-in-place sealing compound designed to be used with our HT1000® sheet material and dovetail gaskets, is available as a standard adder to your gasket order or can be purchased separately. The paste allows end users to cut large diameter gaskets using cost effective dovetail gasket segments. The HT1000® Paste eliminates possible leak paths through traditional dovetail designs and provides one-piece gasket construction and lower leakage rates at an affordable price point.
