Abstract:

Taking polyethylene (PE) pellets, pipes, fittings, and carbon black masterbatch (PE, polypropylene) as research objects, the carbon black contents in different samples were determined by using traditional muffle furnace, tubular electric furnace, thermogravimetric, and microwave muffle furnace methods. The measurement results were analyzed, and the accuracy of these four methods for measuring carbon black content in polyethylene was investigated. The results indicated that thermogravimetric method had a high accuracy and good repeatability.

Key words: carbon black content, tubular electric furnace method, thermogravimetric method
