ABSTRACT:
A process for producing a laminate comprising a metal sheet having thermoplastic material on both sides thereof is described. The thermoplastic material is calendered to produce an upper thermoplastic sheet and a lower thermoplastic sheet. A metal sheet is fed into the nip between the calender rolls in order to contact the metal sheet simultaneously with the upper and lower thermoplastic sheets, thus producing a laminate. Processes for producing a pipe-wrapping material, a roofing structure and a solvent-welded joint are also provided.
