In order to improve the transmission of the High-Frequency Board at high frequency state, we must bring the dielectric properties under control. The composite materials of inorganic powder-PTFE board are the ideal material of high frequency board. In the study, we utilize inorganic powders (SiO2 and Hollow glass particle) to reinforce the PTFE board, then the PTFE/inorganic is completed, we discuss the effect of different of PTFE matrix and the particle sizes and the particle contents on the dielectric, thermal and mechanism properties of PTFE/inorganic Board. The experimental results, show that PTFE resin-emulsion and PTFE film has the similar properties of dielectric, mechanical and thermal behavior. Dielectric and thermal properties are increased, with the increasing of powder content；however the mechanical properties are decreased.
