This book "Transmission Line Design Handbook by Brian Wadell" has a very
comprehensive section on dielectric materials, Chapter 9 Section 9.2
Substrate Dielectrics.

Very simply will slow down. Tpd = (c/(sqr.root Er))

c = the speed of light.

Subject: [SI-LIST] : Dielectric Material Comparison


Does anyone know of a good paper or text that gives an introductory
explanation of how dielectric materials affect signal quality? I have
information comparing the physical properties of commonly used
materials (FR-4, GETEK, Teflon, etc) but I don't understand the
between these properties and what will actually happen to a signal
traveling through that material.
