The SERIES 350 uses the ultimate high-temperature flexible insulating system. The ceramic fiber yarn’s upper temperature limit often exceeds the melting point of the material it insulates.
When an application requires flexible insulation, while pushing Type K or Type N to extreme limits, ceramic fiber insulation is the only choice.
Watlow supplies standard SERIES 350 without color coding or impregnations to minimize contaminating the pure ceramic fiber yarn. Because this insulation has no binders or impregnations, it may “flower” when stripped. Laboratory testing indicates impregnation can decrease the upper use temperature by as much as 1000°F (540°C).
The SERIES 355 construction is a cost-effective, medium insulation build of the popular SERIES 350 heavy-duty construction.
If application temperatures exceed SERIES 350 construction, specify XACTPAK® mineral-insulated, metal-sheathed cable.
