Polyester film

Does anyone out there have any information on Hostaphan 43SM
Polyester Film?  We recently received a sheet film sample from the
company: Pilcher Hamilton Corporation. The fact sheet contains a lot
of good mechanical and optical information, but nothing about its
potential usage with collections materials.

Has anyone used this material in their collections?  Is this a sound
alternative to Mylar-D and Melinex.
