Silica Needled Thermal Insulation & Lagging:
High Temperature, Heat, Fire & Flame Resistant 
1800°F / 982°C Service Temperature

InSilMax™  InsulBatt™ 1800 High Temperature needled silica insulation (lagging) is fabricated from high quality Silica that will not burn and will withstand continuous exposure to temperatures of 1800°F / 982°C with excursions
to 2300°F / 1260°C.

This material resists most acids and alkalis and is unaffected by most bleaches and solvents.  It is highly flexible and conformable.
InsulBattä 1800 High-Temperature
Needled Silica Insulation
Available in 1/8", 1/4", 1/2" & 1" thickness.

Applications for these products include thermal insulation and/or protection of equipment such as piping, valves, engine components, turbine casings, as well as affording personnel protection from high temperature plant equipment.
