To determine the carbon black content of plastics, as per ASTM D 1603, IS 4984 and IS 2530.
The Carbon Black Content Apparatus is used to determine the carbon black content of plastics, as per ASTM D 1603, IS 4984 and IS 2530. Carbon black is added to polyethylene and other plastics for UV protection; the correct percentage is essential, because too little leaves the product vulnerable to sunlight while too much can affect processing and properties — so measuring the exact content is a key quality check for pipes, cables and outdoor products.
In the test, a weighed sample is heated in a furnace under an inert gas stream so the polymer pyrolyses and burns off, leaving the carbon black residue to be weighed and expressed as a percentage. The apparatus has a 10″ × 8″ × 8″ mild-steel furnace reaching 1150°C, and comes complete with the glassware train — desiccator, glass U tube, combustion tube, combustion boat, rotameter and rubber tube, plus glass end caps and traps — needed to run the determination accurately.
