In the application discussed here, the 6750 Freezer/Mill® was used for grinding compact synthetics (pellets, webbing fabric, textiles, etc.) as well as polymer yarns, fleece material, filaments (polypropylene (PP), polyethylene or polyester). Grinding was required for accurate qualitative and quantitative analysis of additives contained in synthetic materials (e.g. antioxidants using HPLC and INOC-Test). The Freezer/Mill is ideal for this application, providing the required particle size reduction in a relatively short time period.
