摘要： Solvent-free polyurethane hot melt adhesives which can be obtained by reacting a composition including a polyether polyol, a polyester polyol, at least one poly(meth)acrylate, and one or more fillers, selected from kaolin, fumed silica, soot, and wollastonite, with a polyisocyanate. In comparison to similar adhesives without a filler content, the adhesives are characterized by significantly improved heat resistance properties while the remaining properties are comparable. Furthermore, in some cases, improved mechanical properties, such as an improved tear strength, could be observed by adding the fillers. The aforementioned hot melt adhesive compositions are therefore suitable in particular for applications in automotive construction, in the textile industry, and in the packaging industry, and in particular for adhering sandwich panels.

摘要： A hot melt adhesive composition is provided which contains at least one silane group-containing thermoplastic poly-α-olefin which is solid at 25° C. and at least one paraffin wax. The hot melt adhesive composition has only low adhesion to uncoated aluminum tool surfaces, wherein at the same time they have high final strengths and thermal stabilities comparable to conventional adhesives, as well as good resistance to environmental influences. The hot melt adhesive is suitable as a laminating adhesive for laminating films made of thermoplastic olefins, which have sufficient stability for subsequent deep-draw lamination.

摘要： A hot-melt glue composition, including a) at least one atactic poly-α-olefin (APAO) that is solid at 25° C.; b) at least one hydrocarbon resin having a softening point of at least 80° C., measured in accordance with the ring-and-ball method according to DIN EN 1238; and c) at least one maleic-anhydride-grafted wax having a softening point of not more than 150° C., measured in accordance with the ring-and-ball method according to DIN EN 1238, which is a maleic-anhydride-grafted polypropylene wax or a maleic-anhydride-grafted polyethylene wax, wherein the proportion of the at least one maleic-anhydride-grafted wax in the hot-melt glue composition is at least 3 wt %. The hot-melt glue composition is characterized by a low reactivation temperature, together with high heat resistance and good adhesion to ABS and nonpolar polyolefin materials. The hot-melt glue composition is well suited for film lamination by vacuum deep-drawing lamination, in particular for applications in automobile construction.
