Carbon Black Content Test Device

Carbon Black ASTM D1603

Carbon black content test device is designed and produced in line with GB/T2951.41 - 2008 <Common test methods for insulating and sheathing materials of electric and optical cables--Part 41: Methods specific to polyethylene and polypropylene compounds - Carbon black and/or mineral filler content measurement in polyethylene by direct combustion>, used for determination of carbon black content in polyethylene, polypropylene, polybutene plastics.

Test Procedure:

A sample of known weight is placed into a weighed combustion boat. The sample is then placed into a 600°C tube furnace under a dry oxygen free Nitrogen purge. After a set time the combustion boat with the burn residue is cooled under the nitrogen purge and weighed. The combustion boat is then placed into a 600°C muffle furnace to oxidize the carbon residue. When the carbon is completely oxidized the combustion boat is cooled and weighed.

Data:

Carbon black content = (B-C)/A*100%;

Mineral filler content = C/A*100%;

The content of the filler = B/A*100%.

B = the mass of the residue from the tube furnace
C= the mass of the residue from the muffle furnace

A= the original mass of the sample
