Carbon Black Content Tester is also named Plastic Ash Content Tester; Ash content test Polypropylene Plastic Ash Content or Carbon Black Purity Testing Machine for the determination of carbon black content in polyethylene, polypropylene and polybutene plastics.The Carbon black in plastic does not show significant enhancement effect, but it can improve its thermal deformation, dimensional stability, rigidity and hardness, etc.

Carbon Black Content Tester DW1421 

Carbon Black Content Tester is used to determine carbon black content in geomembranes,Polyolefin(Polyethylene ,polypropylene and polybutene ) Pipes.

The test of carbon black is obtained through the analysis of the weight of the samples under the protection of nitrogen. The instrument has advantages of convenient operation, simple operation, accurate measurement, high precision and high automation.

Application of Carbon Black Content Tester 

Carbon Black Content Tester is used to determine the carbon black content of geomembranes, polyolefin (polyethylene, polypropylene and polybutylene) pipes and fittings and materials used in particular for the manufacture of pipes and fittings and rubber. It is especially suitable to those users who want strict control on increasing temperature. Carbon Black Content machine belongs t content testing

With the increase of carbon black filling, the tensile strength and impact property of the carbon black are decreased rapidly, and the filling amount varies according to the effect of carbon black in plastics. When the carbon black is required to stabilize and prevent aging, the amount of its addition is 2~3% of plastic. Only 1% or less when it is used; To reduce the surface resistivity by 2%~5%; The content of carbon black in semiconductor materials can be 35%~50%; In chemical crosslinked polyethylene, carbon black can normally be up to 60, or even up to 200.

Carbon Black Content Tester complies with ISO 6964, ISO 247, IEC 60811-4-1, ASTM D1603, GB/T 2951, GB/T 1302 etc international and retailer standards.
