Title
(EN) EPDM ROOFING MEMBRANES MADE BY PROCESSES EMPLOYING A EUTECTIC MIXTURE
(FR) MEMBRANES DE TOITURE EN EPDM FABRIQUÉES PAR DES PROCÉDÉS UTILISANT UN MÉLANGE EUTECTIQUE
Abstract
(EN)
A method of preparing an EPDM roofing membrane panel includes preparing a vulcanizable composition including a eutectic composition by mixing an EPDM rubber, a sulfur-based curative, zinc oxide, and a eutectic composition; forming a sheet from the vulcanizable composition; preparing a green membrane panel using the sheet; and curing the green membrane panel to form the EPDM roofing membrane panel.
(FR)
Un procédé de préparation d'un panneau de membrane de toiture EPDM comprend la préparation d'une composition vulcanisable comprenant une composition eutectique par mélange d'un caoutchouc EPDM, d'un agent de durcissement à base de soufre, d'oxyde de zinc, et d'une composition eutectique ; la formation d'une feuille à partir de la composition vulcanisable ; la préparation d'un panneau de membrane crue à l'aide de la feuille ; et le durcissement du panneau de membrane crue pour former le panneau de membrane de toiture EPDM.
