For assessing carbon black dispersion in polyethylene compounds, as per IS 4984 and IS 4985.
The Carbon Black Dispersion Test Apparatus is used to assess how evenly carbon black is dispersed within polyethylene compounds, as per IS 4984 and IS 4985. Carbon black is added to PE to protect it from UV degradation; if it is unevenly dispersed, some regions remain unprotected and can fail early — so checking dispersion is a key quality requirement for PE pipes, cables and outdoor products.
In the test, a thin film of the compound is prepared on a temperature-controlled hot plate and then examined under a microscope to confirm that the carbon black is uniformly distributed. With an 8″ hot plate (ambient to 200°C) and a microscope offering 100X and 450X magnification on a 6″ screen, the apparatus gives a clear, repeatable assessment of dispersion quality for routine QC and R&D.
