Akzo Nobel Expancel® 551 DE 20 d60 Dry expanded 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: Car underbody coatings; Auto body filler and marine and hobby putties; Cable fillings; Cultured marble; Civil explosives; Modelmaking materials; Sealants (acrylics, PUR, polysulphides, silicones); Synthetic wood
