SK Functional Polymer (SKFP) is a provider of Lotader® recycling agents used to compatibilize plastics blends and improve their mechanical properties.
Recycled PA feedstocks are sometimes be contaminated with small amounts of polyethylene (PE). This contamination, even at low level (10% or less), can affect the mechanical performance of the recycled compound. This results in degraded performances, inferior to virgin PA.
Lotader® 3410 was evaluated to improve the polyamide-polyethylene blend performance in which the PE content is 25 weight percent. Lotader® 3410 ethylene – butyl acrylate – maleic anhydride terpolymer has a high ethylene and MAH contents, making it a good compatibilizer of PE into PA. This unique composition enables a fine dispersion of the PE contaminant into the PA6 matrix. This is necessary to obtain good mechanical properties. It can be added to PA6, PA6,6 or PA12 at loading from 2.5 w% to 10.0 w% to significantly increase the impact resistance and the compatibility with PE.
Lotader® 3410 was tested below to increase PA6 performances by improving its compatibility with the PE pollution.
