Thermal Ceramics K-Shield Felt AG/Min-K Composite
Categories: Ceramic

Material Notes: Thermal Ceramics has recently introduced a composite insulation system which combines the high temperature use limits of ceramic fiber felts with the low thermal conductivity benefits of microporous insulation. This material, a composite of Thermal Ceramics K-Shield Felt AG and the Min-K Division's microporous core, is available in a quilted form. This composite offers several key advantages over either a traditional microporous material, or a quilted fibrous material, while maintaining the low thermal conductivity (shown below) typically seen in microporous products.

The K-Shield Felt AG/Min-K composite is lighter than comparable Min-K materials. The nominal density of K-Shield Felt AG is 6 pcf, resulting in a final core density of 11 pcf for the 16 pcf Min-K and 7 pcf for the 8 pcf Min-K material, while the thermal conductivity stays virtually constant.

Flexible Min-K is consists of a microporous core and an outer textile facing that typically determines the temperature use limit. High temperature cloths (>1200°F) are often very costly but by using the K-Shield Felt AG on the hot face, the additional cost of cloth may be eliminated. Due to the fibrous nature of ½ the thickness of these composites, costly edge binding may be eliminated in some instances.

By employing the K-Shield Felt AG on the Hot Face, the composite can be used at temperatures greater than the standard maximum temperature use limit of the microporous core.

The acoustic properties of Min-K and the K-Shield Felt AG are complimentary as each material offers good sound absorption characteristics at different frequencies.
