Statotherm HT 9560

Features

Statotherm HT 9560 is a gasket made from particularly heat-resistant natural mica. It is available without and with spit plate reinforcement (9560 and 9560/3). The outstanding thermoactive sealing behavior (from around 600 °C) is achieved through a specially developed treatment. The materialʼs expansion ratio actively counteracts any loss of surface pressure, which in turn guarantees the tightness and stability that the gasket needs for sealing even extreme conditions.

Operating range

Pressure:
9560: p = 5 bar
9560/3: p = 40 bar
Temperature

• Continuous operation:
  tmax = + 950 °C
• Inert environment:
  tmax>1,200 °C

Recommended surface roughness:
RZ = 40 … 60 μm

Guaranteed chemical resistance even in many gaseous media.

Sealing parameters
Thermal conductivity coefficient of sealant at 400 °C: λ = 0,35 W/mK Compressive strength for sealant to DIN 52913 (16 hours at 300 °C): 35 ... 40 MPa

Variants

on request: 9560/2: sheet with tanged metal reinforcement in 1.4828
9560/2R: rings and molded parts
9560/2RIG: with tanged metal reinforcement in 1.4828 and eyeletting in 1.4828

Notes

The gasket is normally installed between flat sealing surfaces. Please note that the seal thickness is set during installation as a result of the bolt-tightening forces acting on the flange. The standard thickness of 1.3 mm when new settles to around 1.05 mm with surface pressure of 15 MPa at room temperature. Once this adaption has taken place, there is no further significant settling or flow.
