Pigments and extenders. Methods of dispersion and assessment of dispersibility in plastics - Determination by filter pressure value test Ingestion-build-67170 Manufacturers and suppliers of spectacle1 Scope This part of ISO 23900 specifies a method of assessing the degree of dispersion of a colorant in a thermoplastic polymer. The method is suitable for testing colorants in the form of colour concentrates in all polymers used for extrusion and melt spinning processes. The filter pressure value (FPV) determined according to this method is valid only for the equipment, conditions and test polymer being used. The use of test conditions differing
