In steel manufacturing and industrial ceramic applications, the low thermal conductivity properties of PCW reduced overall carbon emissions for energy savings from 40% to 70% compared to traditional refractory lining. Production in North America and Europe provides local accessibility for shorter lead times. ![Saffil_STEEL.jpg](https://hub.chizbros.com/hs-fs/hubfs/Saffil_STEEL.jpg.webp?width=412&height=279&name=Saffil_STEEL.jpg.webp) ## STEEL ![Saffil_SPACE-1-768x512.jpg](https://hub.chizbros.com/hs-fs/hubfs/Saffil_SPACE-1-768x512.jpg.webp?width=412&height=275&name=Saffil_SPACE-1-768x512.jpg.webp) ## AEROSPACE ![Saffil_CERAMICS-768x512.jpg](https://hub.chizbros.com/hs-fs/hubfs/Saffil_CERAMICS-768x512.jpg.webp?width=421&height=281&name=Saffil_CERAMICS-768x512.jpg.webp) ## CERAMICS ## General Benefits of Saffil PCW ![](https://www.alkegen.com/wp-content/uploads/2025/03/Low-Thermal-Conductivity-150x150-1.png) ### ![Low-Thermal-Conductivity-150x150](https://hub.chizbros.com/hs-fs/hubfs/Low-Thermal-Conductivity-150x150.png?width=100&height=150&name=Low-Thermal-Conductivity-150x150.png) ### LOW THERMAL CONDUCTIVITY ![](https://www.alkegen.com/wp-content/uploads/2025/03/REsistance-to-Thermal-Shock-150x150-1.png) ### ![REsistance-to-Thermal-Shock-150x150.png](https://hub.chizbros.com/hs-fs/hubfs/REsistance-to-Thermal-Shock-150x150.png.webp?width=100&height=150&name=REsistance-to-Thermal-Shock-150x150.png.webp) ### RESISTANCE TO THERMAL SHOCK ![](https://www.alkegen.com/wp-content/uploads/2025/03/Easy-to-Handle-150x150-1.png) ### ![Easy-to-Handle-150x150](https://hub.chizbros.com/hs-fs/hubfs/Easy-to-Handle-150x150.png?width=100&height=150&name=Easy-to-Handle-150x150.png) ### EASY TO HANDLE AND INSTALL ![](https://www.alkegen.com/wp-content/uploads/2025/03/High-Temp-Stability-150x150-1.png) ### ![High-Temp-Stability-150x150](https://hub.chizbros.com/hs-fs/hubfs/High-Temp-Stability-150x150.png?width=100&height=150&name=High-Temp-Stability-150x150.png) ### HIGH TEMPERATURE STABILITY ![](https://www.alkegen.com/wp-content/uploads/2025/03/Insulation-Properties-150x150-1.png) ### ![Insulation-Properties-150x150](https://hub.chizbros.com/hs-fs/hubfs/Insulation-Properties-150x150.png?width=100&height=150&name=Insulation-Properties-150x150.png) ### EXCEPTIONAL INSULATING PROPERTIES ## Saffil® 72HD Anchor-Loc® Modules The Anchor-Loc® Module system is specifically designed for high temperature industrial equipment, constructed of high temperature, lightweight, thermally efficient blankets and proprietary attachment hardware.

Saffil Blankets are virtually “shot” (un-fiberized particles) free, making them an ideal candidate for applications where the presence of shot is undesirable. The low shot content (high fiber index) yields a blanket with extremely low thermal conductivity, outstanding consistency, and resiliency at elevated temperatures.

Saffil fibers are produced by a unique solution extrusion process which ensures the highest level of chemical purity and lowest level of ‘shot’ (non-fiber particles). Available in a variety of grades, Saffil Bulk Fibers are used in demanding industrial environments and aerospace applications. When implemented as a raw material, Saffil Bulk Fiber is be used to produce high temperature polycrystalline wool blankets and modules; and by vacuum formers and wet process forming to increase the maximum use temperature of boards, vacuum formed shapes, and papers.
