    Micro-Tek Corp. Vel-Tek Coax Core allows cable designers to meet the demanding performance character Expanded or Hi-Vec-type core offers the ability to be produced with a VoP between 78 and up to 90% (with an ideal construction) with relatively good Increasing this core’s VoP will improve its phase stability as there will be even less PTFE per unit volume than that of either low-loss or fully sintered conventional core.  This type of core sometimes competes with the tape-wrapped core.  Its advantages over PTFE tape wrapping are that it can be made to a higher VoP and is mechanically more robust than tape wrap (the seams in tape wrapping can sometimes be problematic).  PTFE tape wrap will have a little lower loss as it is generally completely unsintered and has no tie layer.  The electrical performance of the expanded core is very good at high frequencies.

Applications include high frequency/microwave military, aerospace, communications and testing.

PTFE has the lowest dielectric constant (highest velocity of propagation) and lowest loss tangent of any plastic making it ideal for use in coaxial core applications.  Fully sintered PTFE is very robust as a dielectric.  Core made with PTFE are subject to phase instability, primarily around its first order transition temperature of about 66 F.  Phase instability will cause signal delay in a coaxial cable.
