Thermal Gaskets

Max Temperatures of Fabrics

• Linen is highest temperature-resistant material? [1]
• What about wool? 600C for lightning temperature - [2]. Cellulose is 250C by comparison.
• Natural wool felt - looks like max temp is 200F - [3]
• PBI Polybenzimidazole
  • Supposeldy (ie double check this)
  • Other features: continuous temperature: 540 °C (1,004 °F), does not melt but degrades around the temperature: 760 °C (1,400 °F) under pyrolysis, retains fiber integrity and suppleness up to 540 °C (1,004 °F)
• Mettalized fibers?
