摘要： The invention relates to thermoplastic molding compounds having melt viscosities of less than 30,000 mPas for use as a hot-melt adhesive, comprising the components A and B, wherein component A comprises one or more C3/C2 copolymers each produced with metallocene catalysts and each having a melt viscosity at 170° C. of less than 20,000 mPas, measured according to DIN 53019, and a molecular weight MW of 1000 g/mol to 50,000 g/mol, and component B comprises one or more C2/C3 copolymers each produced with metallocene catalysts and each having a melt flow index MI of 1 to 100 g/min, measured at 190° C./2.16 kg, according to ASTM D 1238, and a molecular weight MW of 50,000 g/mol to 300,000 g/mol. Said thermoplastic molding compounds, because of the viscosity and mechanical properties thereof, are suitable for fiber mesh applications.
