Determination of Carbon Black Content in Polyethylene Compounds ASTM D4218

Determination of Carbon Black Content in Polyethylene Compounds ASTM D4218

The ASTM D4218 test method uses the Muffle-Furnace technique to determine the presence of channel or furnace black in black polyethylene compounds. This testing process can generate duplicate test data in 20 minutes or less for a simple carbon black content measurement.

    Scope:

    ASTM D4218 test method is used to determine the carbon black content in polyethylene compounds by the Muffle-Furnace technique. The muffle furnace is an important laboratory testing tool that is used to test a variety of materials. With this technique, ASTM D4218 is aimed to provide improved temperature uniformity and isolate heated materials from combustion pollutants. This test method provides high performance and is appropriate for quality control in manufacturing, technical support, and research. The test is conducted at high temperatures ranging from 600°C to 900°C. 

    Procedure:

    For ASTM D1428, a black polyethylene compound enclosed in a disposable aluminum weighing dish is pyrolyzed for a brief period in a muffle furnace. The air in the muffle furnace becomes oxygen-deficient during the pyrolysis of the polymer, preventing the residual carbon black from being burned. Any soot generated during the early combustion of the gases is consumed before the carbon black. After cooling, the carbon black residue is weighed. The dish and contents can be reinserted into the muffle furnace to determine ash content, with the findings being used to calculate true carbon black content. 

    Specimen size

    The ASTM D1428 test specimen may be in the form of granules or pieces cut from an article such as pipe, jacket, film, molding, etc. 

    Data:

    The percent carbon black content is calculated as follows :

    where, 

    W1, W2, W3, and W4 are weights of the dish at four different times during the whole test procedure.
