SHOE PRESS ROLL COVER
A shoe press roll cover for a machine for producing and/or finishing a fibrous web, such as a paper, card or tissue web, is formed of a matrix material composed of polyurethane, formed essentially from 4,4′-MDI as isocyanate, at least one polyol and at least one crosslinker. The polyurethane matrix...

| description | A shoe press roll cover for a machine for producing and/or finishing a fibrous web, such as a paper, card or tissue web, is formed of a matrix material composed of polyurethane, formed essentially from 4,4′-MDI as isocyanate, at least one polyol and at least one crosslinker. The polyurethane matrix material is biobased to an extent of at least 20% by weight. The polyol and the crosslinker are selected from one of several combinations: a) biobased PTMEG as polyol and a mixture of MCDEA and PTMEG as crosslinker; b) polycarbonate as polyol and a mixture of MCDEA and biobased polycarbonate polyol as crosslinker; c) a mixture of biobased polycarbonate polyol and PTMEG as polyol and 1,4-BDO as crosslinker; d) PTMEG as polyol and a mixture of PTMEG and MCDEA as crosslinker, with the 4,4′-MDI in the isocyanate and the PTMEG in the polyol being biobased. |
