Halcro,
The purpose of a mat is to provide a stable surface with a similar impedance of the record, or so they say. Some think the best mats are forms of acrylic, methacrylate (Delrin), carbon, or vinyl. The trick is in preventing vibrations from reflecting back to the record. Achromat does this with bubbles somehow. Perhaps a lead sheet would be more affective.
Beside the obvious problem of weight, lead is soft and manufacturing a flat sheet might be a problem, but I doubt if any material is more affective at slowing vibrations. A lead sandwich or under mat might be ideal.
Regards,
