esietendust

Esietendust is a term used in industrial and scientific literature to denote a fine particulate powder with variable composition. It is not a single substance, but a class of powders defined by the producer for a given grade or application.

Typical properties include small particle size and variable shapes; particle sizes commonly range from about 0.5 to 100 micrometers, with varying bulk density and surface area depending on processing and coatings.

Production methods include milling of solids, spray drying of suspensions, or chemical synthesis for polymer-based particles. Surface treatments, such as silane or polymer coatings, can tailor compatibility with matrices and additives.

Applications span coatings, inks, plastics, cosmetics, and laboratory research as fillers, carriers, catalysts supports, or adsorbents. It is also used as a model particulate in aerosol and flow experiments.

Safety and handling emphasize potential inhalation and eye hazards. Practices typically include containment, dust suppression, adequate ventilation, and personal protective equipment. Regulatory status varies by jurisdiction and by the material's composition.
