This application note describes the analysis of a sample of an ASA/ABS-blended material from a car door panel by gel permeation chromatography (GPC), using Agilent PLgel 5 µm MIXED-C columns.
This document is an application note detailing the analysis of injection-molded thermoplastics, specifically a blend of acrylonitrile/styrene/acrylate (ASA) and acrylonitrile/butadiene/styrene (ABS), using gel permeation chromatography. The study demonstrates that these blended materials can elute as a single monomodal peak when the components have similar molecular sizes.
