Expancel WU
Wet, unexpanded microspheres with 70% solid content
Expancel wet, unexpanded (WU) microspheres are ideal for developing waterborne products. Particle sizes range between 6μm and 24μm (20µm - 80µm in expanded form) offering suitable foaming even in low temperatures.
Our low density, highly expandable Expancel WU microspheres lets you increase volume, without adding weight. This, added to its closed cell structure and ability to withstand compression, makes Expancel WU an incredibly useful ingredient in printing ink, wallpaper, polyester film and more.
