Abstract

Przedmiotem zgłoszenia jest sposób polepszania przezroczystości poliamidu PA6, który polega na tym, że wysuszony granulat poliamidu PA6 i wysuszony granulat poliamidu PA69 poddaje się procesowi kompandowania w stosunku od 99:1 do 70:30, korzystnie od 90:10 do 80:20, w temperaturze 230 - 280°C, korzystnie 250 - 260°C, a następnie stopioną blendę formuje się w postaci żyłki, którą schładza się i zestala w wannie chłodzącej, po czym poddaje procesowi granulacji.The subject of the application is a method of improving the transparency of polyamide PA6, which consists in that the dried PA6 polyamide granulate and the dried PA69 polyamide granulate are subjected to a compounding process in the ratio from 99: 1 to 70:30, preferably from 90:10 to 80:20, in temperature 230 - 280 ° C, preferably 250 - 260 ° C, and then the molten blend is formed into a string, which is cooled and solidified in a cooling bath, and then subjected to the granulation process.
