Carbon Black Content Tester - QualiCBCT™-200
Carbon Black Content Tester for Polyethylene, Polypropylene and Cable Compounds (4 Samples)
The QualiCBCT™-200 Carbon Black Content Tester measures carbon black in polyethylene, polypropylene, polybutylene, and cable compounds through high-temperature pyrolysis in nitrogen. Pipe extruders, cable makers, compounders, and test labs use it to confirm the specified pigment loading. Each run handles four samples, which shortens batch release in busy QC labs. The tube furnace reaches 1150 °C and switches gas lines automatically. Operators set programs on a 7-inch touchscreen and read calculated results directly.
Carbon black gives black polyolefins their resistance to ultraviolet degradation. Too little pigment leaves pipe and cable jackets open to sunlight damage, while excess pigment adds cost without extra protection. A fast, repeatable content check lets QC teams catch dosing errors before material ships. The QualiCBCT™-200 follows the pyrolysis approach described in ASTM D1603 and ISO 6964.
Qualitest designed this tester for daily production control and development work alike. A customized guide-rail holder positions all four specimens in the heated zone. Rapid cooling brings the chamber from 900 °C to room temperature in 20 minutes or less. An exhaust filtration device treats pyrolysis fumes before discharge. Built-in printing produces a hard-copy record for every test, which supports traceable QC documentation.
