ISO 23900-5:2015 spécifie une méthode permettant d'évaluer le degré de dispersion d'un pigment dans un polymère thermoplastique.
Cette méthode convient pour la mise à l'essai de pigments sous forme de concentrés colorés dans tous les polymères utilisés dans le domaine de l'extrusion et de la fabrication de fibres.
La valeur de pression du filtre (VPF) déterminée conformément à la présente méthode n'est valable que pour l'équipement, les conditions et le polymère d'essai utilisés. La mise en ?uvre de conditions d'essai différentes de celles spécifiées peut conduire à des résultats différents. La méthode de préparation du concentré coloré n'est pas précisée dans la présente partie de l'ISO 23900. Les résultats obtenus avec chacun des pigments ne sont donc comparables que si les concentrés colorés ont été préparés suivant la même méthode.

Overview

EN ISO 23900-5:2018 (ISO 23900-5:2015) defines a laboratory method to assess the degree of dispersion of a colourant (pigment or extender) in a thermoplastic polymer using the filter pressure value (FPV) test. The method is tailored for colour concentrates used in extrusion and melt‑spinning processes and provides a reproducible way to quantify dispersibility under defined equipment and test conditions.

Key topics and technical requirements

• Scope & purpose: Measures dispersibility of colour concentrates in polymers for extrusion/melt‑spinning; results are valid only for the specific equipment, test polymer and conditions used.
• Filter Pressure Value (FPV): Defined as the pressure difference between the start pressure and the maximum pressure recorded in front of a screen pack during extrusion. FPV is the primary metric for dispersion assessment.
• Materials:
  • Colour concentrate - homogeneous preparation of pigment/extender in a thermoplastic carrier.
  • Basic test polymer - grade/type agreed between parties (development work used polypropylene).
  • Test mixture - specified blend of colour concentrate and test polymer.
• Apparatus:
  • Single‑screw extruder with a non‑grooved barrel and a screw without dispersing elements.
  • Melt pump and melt pressure transducers (one in front of the filter/screen pack).
  • Breaker plate and defined screen‑pack configurations.
  • Screen‑packs and sealing rings as specified to generate reproducible pressure responses.
• Procedure & evaluation:
  • Pre‑conditioning and controlled extrusion of the test mixture.
  • Record start pressure and peak pressure; calculate FPV.
  • Test repeatability depends on identical sample preparation and equipment setup.
• Limitations:
  • The method does not prescribe how colour concentrates are prepared - comparability requires same preparation method.
  • Results can vary with different extruder designs, screw geometries or test polymers.

Practical applications

• Quality control of pigment/extender dispersibility in polymer compounds.
• Comparative screening of colour concentrates during R&D and product development.
• Supplier acceptance testing and batch verification for colour concentrates.
• Troubleshooting dispersion issues in extrusion or melt‑spinning operations.
• Process optimization to minimize filter blockages and improve product consistency.

Who should use this standard

• Pigment and extender manufacturers
• Polymer compounders and masterbatch producers
• Extrusion and melt‑spinning equipment manufacturers
• Quality control and R&D laboratories in plastics and textile sectors

Related standards

• Other parts of ISO 23900 series (Parts 1–6) cover general introduction, two‑roll milling methods and film tests.
• EN ISO 23900-5:2018 supersedes EN 13900-5:2005.

Keywords: filter pressure value, FPV, dispersion, pigments, extenders, colour concentrates, thermoplastic polymer, extrusion, melt‑spinning, dispersibility.
