In April 2016 Manchester eScholar was replaced by the University of Manchester’s new Research Information Management System, Pure. In the autumn the University’s research outputs will be available to search and browse via a new Research Portal. Until then the University’s full publication record can be accessed via a temporary portal and the old eScholar content is available to search and browse via this archive.

Abstract

Polyamide 6 is popular engineering polymer used for many applications including filament production via melt spinning. Currently there is no market leading masterbatch suitable for addition at the melt spinning stage used for imparting flame retardant properties. Flaming drips are a common problem and new tighter regulations are causing new additives to be assessed and greater consideration to be taken when developing such product. Flame retardant additives were assessed for dispersion, thermal gravimetric analysis, melt spinning performance, mechanical properties retention and efficacy under DIN 4102-B2 testing. A masterbatch was developed in association with Americhem Europe, masterbatch supplier for the thermoplastic industry in Europe. Although further investigation into certain aspects of the development are necessary to optimise the product.
