Adhesion behavior of poly(urethane) foam on thermoplastics — •Jörg Kressler, Karsten Busse, Nasir Mahmood, Jörg Kressler, Karsten Busse, and Nasir Mahmood — Fachbereich Ingenieurwissenschaften, Martin-Luther-Universität Halle-Wittenberg

Detailed characterization of polymer surface properties under structural and morphological aspects is a high priority activity In our study three formulations of poly(urethanes) are foamed in contact with different thermoplastic materials. A thin PU-film at the interface is responsible for the adhesion behaviour which is investigated XPS, ToF-SIMS, TEM, NR and other methods. It was found that silicon oil remains on the foam side after skinning from TP and parts of the foam are linked to the TP surface. The thin film at the interface is regularly structured with alternating layers with a typical thickness of 250-300 nm.
