摘要: The invention provides resin- and mineral oil-free pressure-sensitive adhesive compositions, comprising 55%-100% by weight of a copolymer of propylene and one or more further monomers selected from the group composed of ethylene and 1-olefins having 4 to 20 carbon atoms, wherein the copolymer has been prepared with the aid of metallocene catalysts and is characterized by
a. a melt viscosity at 170° C. of 20 to 8000 mPas (DIN 53019);
b. a density of 0.84 to 0.90 g/cm3 (23° C., ISO 1183);
c. a glass transition temperature of less than −30° C. (DIN EN ISO 11357-2:2014); and
d. a flow point, measured according to ASTM D97, of less than 50° C.,
which due to their permanently tacky properties are suitable as pressure-activated pressure-sensitive adhesives.
