ISO 18553 carbon black dispersion test equipment , Method for the assessment of the degree of pigment or carbon black dispersion in polyolefin pipes, fittings and compounds

This document describes a method with two procedures for the assessment of carbon black or pigment particle and agglomerate size, and the rating of dispersion in polyolefin pipes, fittings and compounds.

The method is applicable to polyolefin pipes and fittings, as well as raw material in pellet form, with the choice of procedure to be determined by the referring specification.

The method is applicable to carbon black or pigmented polyolefin pipes, fittings and compounds with a carbon black content of less than 3 % by weight, and pigment content of less than 5 % by weight.

UNITEDTEST UT3600 Carbon black dispersion tester is used to measure the carbon black dispersion in polyolefin pipes, fittings and compounds. Adaptive to measuring software, and the microscope, measure the size, form, dispersion condition of the carbon black granule, can built the internal connection of this parameter with mechanical property, anti-static function, moisture absorption performance etc., it's an necessary instruments for quality control, new product R&D department. Conform with standard ISO 18553.  ASTM D2663
