Walki Group Oy has developed polyurethane foam cover materials that can increase output and give a cleaner production environment.
The Espoo, Finland, firm says its Walki paper-based foam carriers can cover all of the inner walls of a foaming line where PUR is injected and expands. Walki claims the covers can stabilize production and help chemical hold-out. Usage of chemical products is reduced by about 3 percent, Walki claims.
Use of the covers makes it easier to keep foam lines clean and the covers run easily on a PUR line compared with standard polyethylene films and conventional processing paper, according to Walki.
Peelable protection paper is used for top, side and bottom layers in PUR foaming while the Cover Foam product is a universal carrier in the foaming process.
