Pigments and extenders. Methods of dispersion and assessment of dispersibility in plastics - Determination of colouristic properties and ease of dispersion in plasticized polyvinyl chloride by two-roll milling not-for-sale It applies to the design1 Scope This part of this ISO 23900 specifies a method of determining the colouristic properties of a test pigment relative to a standard, and the ease of dispersion DHPVC P of pigments from the differences in colour strength on dispersing colouring materials under various conditions in plasticized polyvinyl chloride (PVC P) compounds. The method is appropriate for use with organic and inorganic black and colour pigments and for pigment preparations.
