Akzo Nobel Expancel® 461 DU 20 Dry unexpanded microspheres

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;
