Abstract
(A1) Die vorliegende Erfindung betrifft eine thermoplastische Formmasse, die eine Matrixphase, die einen Staerkeester sowie einen Weichmacher umfasst, sowie einen in der Matrixphase homogen verteilten nanoskaligen Fuellstoff enthaelt.

 

DE 102008025697 A1 UPAB: 20091222 NOVELTY - The thermoplastic molding mass comprises a matrix phase made of starch ester and plasticizer and containing nanoscale filler, where the starch ester has a degree of substitution of 2.1-2.9. The filler has cation-exchange capacity of 30-250 mval (milliequivalents) per 100 g. The weight portion of the matrix phase related to the molding mass is 99.9-80 wt.%. The weight portion of the nanoscale filler related to the molding mass is 2.5-7.5 wt.%. The weight portion of the plasticizer related to the molding mass is 15-25 wt.%. The nanoscale filler has average particle size (d50) of 2-8 mu m. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) a method for producing a thermoplastic molding mass; (2) a molded part; and (3) a method for producing a molded part. USE - Thermoplastic molding mass useful for producing a molded part, which is useful for buttons, fitting grips, keyboards, toys, packaging, films, films for coating and/or coatings in the construction and/or furniture industry (all claimed). ADVANTAGE - The thermoplastic molding mass can be efficiently produced with high mechanical strength, high tensile strength, high stiffness and reduced brittleness thus ensuring effective and economical production of the molded part with less effort.
