Construction Highlights

Thermiculite 896 combines exfoliated vermiculite and steatite with a thin 50 µm 316 stainless steel foil core. It features a smooth reinforcement and chemical bonding, unlike the tanged stainless steel core found in Thermiculite 815. Published ratings are 1,000 °C and 150 bar, but these do not represent an allowable simultaneous operating point. The typical 1 mm thickness and 1,000 × 380 mm sheet format make dimensional availability particularly critical.

Applications and Service Conditions

The technical data sheet specifies a thin-profile construction engineered for narrow sealing faces, low bolt load thermal applications, and marine environments. Its documented oxidation resistance provides a distinct advantage over traditional flexible graphite. Rated up to 150 bar (catalogue limit; not to be combined concurrently with 1,000 °C). The data sheet notes a typical thickness of 1 mm and a 1,000 × 380 mm sheet format.

Preparing for Material Selection or Replacement

Compare with 815 for vermiculite technology, and against foil-reinforced graphites to properly assess construction characteristics. Oxidation performance and material qualifications are not interchangeable. When selecting a sealing material, verify the media, flange geometry, bolting specifications, thermal exposure duration, and required certifications.

Also compare Flexitallic Thermiculite 815 and KLINGER Graphite Laminate SLS. These cross-references do not validate interchangeability.
