Abstract (en)
Heat-sealable sheet material for use in the fabrication of lapped-seam membranes. In a presently preferred construction, linear low density polyethylene film is adhered to one lateral border of cured polymerized EPDM composition; preferably the adhesive is protected with a removable liner, e.g., a polyester film until lapped-seam splicing is to be carried out. A transfer tape based on thermoplastic heat-sealable adhesive carried by a strippable liner also constitute part of the invention. The transfer tape is advantageously applied to a sheet of uncured EPDM compound and the resultant assembly subjected to heat and pressure to cure the compound and bond the heat-sealable adhesive firmly thereto.
