Wire and cable carbon black content tester

Transaction customer
Selection guide

The carbon black content tester is suitable for the determination of carbon black content in polyethylene, polypropylene and polybutene plastics. The test of carbon black is obtained by gravimetric analysis of the sample after decomposition under nitrogen protection at high temperature. The instrument has the advantages of convenient use, simple operation, accurate measurement, high precision and high degree of automation. 


Standards: ISO 6964, GB/T 13021, IEC 60811-4-1, GB/T 2951.41, JTG E50 T1165, etc.

GB/T2951.41-2008 "General test method for insulation and sheathing materials of cables and optical cables"

Why test for carbon black?

The performance of plastic products is related to the amount of carbon black, carbon black has the ability to prevent ultraviolet light, the purpose of adding carbon black to plastic is to resist aging and color, and the detection of carbon black content is actually to detect the product quality of plastic parts.

Instrument features:
