Pigments and extenders. Methods of dispersion and assessment of dispersibility in plastics - Determination by film test1 Scope This part of ISO 23900 specifies a method assessing the degree of dispersion of colorants1 and or extenders in a thermoplastic polymer. The method is suitable for testing colorants and or extenders in the form of concentrates or compounds in all polymers used for extrusion processes.
