THERMOPLASTIC ROOFING MEMBRANES ADAPTED FOR ADHESION TO POLAR ADHESIVES
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.
L'invention concerne un procédé de préparation d'une membrane de toiture thermoplastique, le procédé consistant à (i) extruder une composition comprenant un polymère thermoplastique et une charge minérale pour former un extrudat; (ii) former l'extrudat en une feuille ayant des première et seconde surfaces planes; (iii) laisser la feuille refroidir au moins partiellement; et (iv) traiter mécaniquement la première surface plane de la feuille pour ainsi exposer la charge minérale.
