Akzo Nobel Expancel® 091 DU 80 Dry unexpanded microspheres
Categories: Other Engineering Material; Additive/Filler for Polymer; Polymer; Thermoplastic

Material Notes: Expancel microspheres are thermoplastic hollow spheres. The microspheres are white spherically formed particles with a thermoplastic shell encapsulating a gas. When the microspheres are heated the thermoplastic shell softens and the gas increases its pressure, resulting in an expansion of the spheres.

Applications: Anti-slip coatings; Printing ink; Car underbody coatings; Industrial non-woven textiles;
