Part # SW1800, Firwin SW1800 Insulation

Firwin SW1800 is a unique insulating blanket material with excellent performance in high-temperature applications with stability and resistance to chemical attack. SW1800 is unaffected by incidental spills of oil or water. Thermal and physical properties are restored after drying. This product has been specially developed to meet the demanding health and safety requirements of the European Union.

Features
  • Resistant to thermal shock
  • Provide low thermal conductivity and low heat storage
  • Enhanced solubility in body fluids
  • Cleaned during production to remove any organic matter to minimize out-gassing on initial startup.
