It is usually only used for Rf circuits (UHF and above) because of it's
favourable dielectric properties. It is /horrendously/ expensive.

It does not look white when used as a PCB material, brownish really but
the colour is difficult to to describe. The surface texture, however is
quite unique - and also difficult to describe.
