Abstract
A method of preparing a thermoplastic roofing membrane, the method comprising (i) extruding a composition including a thermoplastic polymer and a mineral filler to form an extrudate; (ii) forming the extrudate into a sheet having first and second planar surfaces; (iii) allowing the sheet to at least partially cool; and (iv) mechanically treating the first planar surface of the sheet to thereby expose the mineral filler.
