VERBUNDMATERIAL AUS POLYURETHAN UND ZUMINDEST EINEM THERMOPLASTISCHEN KUNSTSTOFF, EIN VERFAHREN ZU DESSEN HERSTELLUNG SOWIE DESSEN VERWENDUNG IN KRAFTFAHRZEUGEN

摘要

A composite material comprises (A) a layer of polyurethane (PUR) directly bonded with (B) a layer of a different thermoplastic. (A) contains homogeneously dispersed particles, of size 1-10 nm, coated with a thermoplastic other than (A) and showing a total surface area at least equal to the total interfacial area between (A) and (B). An Independent claim is also included for a process for the production of this material by applying layer (A) to layer (B).
