Thermiculite 815 Tanged Sheet

Product catalog summary

Product Overview
Thermiculite® 815 Tanged Sheet is a high-temperature sheet material reinforced with a 0.004-inch thick 316 stainless steel tanged core. It is part of the Critical Service Series, designed for high-temperature applications.

Specifications
- Maximum Service Temperature: 1800°F (982°C)
- Maximum Tested Pressure: 2900 psi (200 bar)
- Thickness Options: 1/32", 1/16", 1/8"
- Sheet Size: 1 m x 1 m, 60" x 60" (special)
- Can be laser and waterjet cut

Physical Properties
- Facing Density: 75 lb/ft³
- ASTM F36 Compressibility: 33% (1/32"), 44% (1/16", 1/8")
- ASTM F36 Recovery: 13% (1/32"), 9% (1/16", 1/8")
- BS 7531 Gas Permeability: 0.06 mL/min (1/32"), 0.13 mL/min (1/16"), 0.17 mL/min (1/8")
- BS 7531 Stress Retention @ 570°F: 4930 psi (1/32"), 4500 psi (1/16"), 2470 psi (1/8")
- ASTM F38B Creep Relaxation: 23.5% (1/32")

Performance and Testing
Graph 1 shows the loss of load over time for graphite as a function of temperature, indicating that Thermiculite maintains stability at high temperatures. Unlike graphite, Thermiculite does not exhibit increased load loss over time at operational temperatures.

Graph 2 and Graph 3 illustrate the cumulative iso-thermal weight loss and relaxation of Thermiculite compared to exfoliated graphites, demonstrating superior thermal stability.

Design Properties
- m: 2.0
- Y: 2,500 psi
- Gb: 1,906 psi
- Gs: 456 psi
- Tightness Parameter (Tp): MIN 18, MAX 58,645
- S100: 4,788 psi
- S1000: 7,588 psi
- S3000: 9,400 psi
- S10000: 12,026 psi
