Carbon Black Content Tester

Model: UT3500A, ISO 6964, ISO 1408

Carbon black content tester is used to measure the carbon content in PE, PP, PB etc. , sample under nitrogen condition, through high temperature pyrolysis, then measure the weight to get the carbon level.  With feature of easy operation, working reliable, and result high accuracy. 

General Introduction

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.


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