example

[0213] The components indicated in Table 1 were mixed in a ZSK 26 compounder twin-screw extruder from Coperion Werner & Pfleiderer (Stuttgart, Germany) at a temperature of about 280°C. Mix, drain into water bath as a strand, cool until ready to pellet and granulate. The pellets were dried to constant weight in a vacuum oven at 70°C.

[0214] These pellets were then processed on an Arburg A470 injection molding machine at a melting temperature ranging from 270°C to 290°C and a tool temperature ranging from 80°C to 100°C to produce test pieces with dimensions 80mm x 10mm x 4mm Samples and circular plates with a diameter of 80mm and a thickness of 0.75mm, 1.5mm or 3mm.

[0215] The mechanical properties of the products produced from the compositions according to the invention were determined in the bending test according to ISO 178 and in the Izod impact test according to ISO 180 / 1U.

[0216] Glow-wire resistance is determined according to IEC 60695-2-12 by means of the glow-wi...

Abstract

The invention relates to polyamide-based compositions comprising at least one filler from the group comprising alumina, boron nitride and triclinic aluminium silicate, and to the use of said compositions for the manufacture of products with higher fireproofing requirements, especially preferably products with higher glow wire requirements, in particular component parts for live components and voltage-carrying components in domestic appliances.

Description

[0001] This application is a divisional application of an invention patent application with an application date of March 17, 2015, an application number of 201580016528.0, and an invention title of "flame-retardant polyamide composition". technical field [0002] 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 items having a relatively high Products with flame retardancy requirements, especially those with relatively high glow wire requirements, especially those used for current and voltage conducting parts in household appliances. Background technique [0003] Polyamide compositions are used in various applications from the automotive industry to the electrical and electronic fields because of, inter alia, their excellent properties with regard to strength, toughness, processability and their very...
