Quartz Honeycomb

Thermal Properties

The Quartz Honeycomb core has a unique feature of low Coefficient of Thermal Expansion (CTE). Below are comparisons of CTE in the thickness direction of various honeycomb cores. 

Dielectric Properties

The dielectric constant and the loss tangent factor of Quartz are the most distinguished amongst all mineral fibers. Properties of UQF-105-1/4-3.0 honeycomb core test at average frequencies of 9.5 GHz:
