Abstract

A protective material, based on poly-.alpha.-olefins, capable of easy application in molten form, is distinguished by a balanced pattern of properties, good adhesion and good recycling capability. The present protective materials contain (I) not less than 50% by weight of one or more largely amorphous poly-.alpha.-olefins, composed of (a) 3 to 75% by weight of one or more .alpha.-olefins containing 4 to 10 carbon atoms, (b) 25 to 95% by weight of propene, and (c) 0 to 20% by weight of ethene; (II) not more than 30% by weight of other olefin homo- and copolymers which may be either largely amorphous or preferably partially crystalline; and (III) not more than 40% by weight of additives which are standard in the plastic sector. Such protective materials can be used in particular in the underfloor region of motor vehicles.
