Patent ID: 7786193

Claim:
A thermoplastic reinforcing material for shoe production, in the form of a hot-melt adhesive/filler material compound, characterized in that it comprises a) one or several hot-melt adhesive(s) in amounts of 50 to 95 weight %, comprising one or more polymers, where the polymer(s) have an MVR values (measured at 100° C., 21.6 kg based on DIN ISO 1133) ranging from 2 to 300 cm 3 /10 min and b) one or several filler materials in amounts of 50 to 5 weight %, which do not dissolve in the hot-melt adhesive; and the hot-melt adhesive/filler material compound simultaneously meets the following parameters by having: 1) an MVR value between 2 and 6 cm 3 /10 min; 2) a surface stickiness/tack/measured according to DIN EN 14610 at 65° C. of at least 10N to maximally 60N; 3) a bonding value/peeling strength/toward top materials and linings of at least 30 N/5 cm, measured on the basis of DIN 53357; 4) a maximum longitudinal extension of 25% measured after 5 minutes in a hot cabinet at temperatures of 90° C.; wherein component a, the hot-melt adhesive, is present in amounts of 50-95% and comprises a mixture of 1) a linear polyester present in amounts of 75 to 100 weight % and/or a thermoplastic polyurethane present in amounts of 75 to 100 weight %, together with 2) ethylene vinyl acetate copolymers present in amounts of up to 25 weight % with a vinyl acetate content of 10 to 40 weight % and that component b, the filler material is present in an amounts of 50 to 5 weight % and is selected from the group of inorganic, mineral filler materials, organic plant filler materials, plastic materials and mixtures thereof, which are present in the form of spherical, polyhedral particles with a particle-size distribution between 45 and 1000 μm or in the form of fibers with a length of 45 to 1000 μm.
