Weigh and dissolve the fish oil in the xylenes and add to a high-density polyethylene (HDPE) mixing jar that is about one-quarter filled with alumina grinding media. The size of the jar and the media are determined by the batch size being processed. 

The continuing interest in changing the combustion characteristics of composites has focused attention on ATH (alumina trihydrate) filled high density polyethylene. Attempts to incorporate high loadings of ATH into HDPE normally leads to processing difficulties and degradation of composite properties.
