Thermal Ceramics K-Shield Felt
Categories: Ceramic; Oxide; Aluminum Oxide

Material Notes: K-Shield Felt products are produced from premium, cleaned Kaowool high-purity fibers and a special thermosetting binder system in a unique paper-making process. The cleaning process improves the thermal conductivity, insulating value, and vibration resistance of the felt, while also making it an ideal product for die-cutting, fabrication, and handling. K-Shield Felts are both compressible and resilient, while exhibiting excellent flexibility and handling strengths. The special binder system eliminates smoke problems and allows for minimal off-gassing. Due to their unique semi-rigid yet flexible form, K-Shield Felts offer some special properties in comparison to traditional blankets and papers.

The standard K-Shield Felt, K-Shield Felt LS, and K-Shield Felt AG are premium, low-shot products produced from cleaned high-purity ceramic fibers. The K-Shield Felt LS is a very clean, lower-shot product developed for those very demanding applications. These products have very low thermal conductivities and exhibit excellent vibration resistance.

The K-Shield Felt AG is designed specifically for aerospace insulation applications and is approved for both the BMS9-19 and AMS 3680-Rev. C specifications. These approvals include meeting specific tests related to optimum performance in aerospace insulation applications.
