In the past we have used a Teflon coversheet with
acrylic adhesive made by DuPont.  I'm not sure if
they make the coversheet with a flame retardant
acrylic.  The coversheet has been available in
the past with .002" Teflon and .001" acrylic.
DuPont part number is LT-0210.  Let me know if
you need a contact at DuPont.
