[0212] At a temperature of about 280°C, the components indicated in Table 1 were put in a ZSK 26 compounder twin screw extruder from Coperion Werner & Pfleiderer (Stuttgart, Germany) from Coperion Werner & Pfleiderer (Stuttgart, Germany) Mix, discharge into a water bath as a strand, cool until ready to be granulated and granulated. The pellets were dried to constant weight in a vacuum drying oven at 70°C.

[0213] These pellets were then processed on an Arburg A470 injection molding machine at a melting temperature in the range from 270°C to 290°C and at a tool temperature in the range from 80°C to 100°C to produce a test with a size of 80mm×10mm×4mm Samples and circular plates having a diameter of 80mm and a thickness of 0.75mm, 1.5mm or 3mm.

[0214] The mechanical properties of the products produced from the composition according to the invention are determined in a bending test according to ISO 178 and in an Izod impact test according to ISO 180 / 1U.

Abstract

The present invention relates to polyamide-based compositions comprising at least one filler from the group comprising aluminum oxide, boron nitride and triclinic aluminum silicates and to the use of said compositions in the manufacture of Products, especially preferably products with higher glow wire requirements, especially in household appliances for the use of live parts and component parts of live parts.

Description

Technical field [0001] The present invention relates to polyamide-based compositions comprising at least one filler from the group consisting of alumina, boron nitride and aluminum silicate, and also the use of these compositions for the production of: Products with high flame retardancy requirements are particularly preferred, products with relatively high glow wire requirements, especially components used for current and voltage conduction parts in household appliances. Background technique [0002] The polyamide composition is used in various applications from the automotive industry to the electrical and electronic fields because of its excellent properties in terms of strength, toughness, processability, and its very good solvent resistance, among others. In the electrical and electronic fields, in particular, due to increased fire risks triggered by, for example, short circuits, arcs or broken wires, there are often increased requirements in terms of flame retardancy of non...
