Expancel® microspheres

Expancel microspheres are available as unexpanded or expanded. We deliver them in six different forms, all of them highly sophisticated and developed for different purposes.

Expancel WU — Wet, unexpanded microspheres

Expancel WU is used in waterborne products and heat is needed to cause expansion of the microspheres in the product. For example, it can be used for carpet underlays to increase friction. The solid content is about 70%.

Expancel WE — Wet, expanded microspheres

Expancel WE is used in waterborne products such as paints and crack fillers to reduce weight and improve applicability. The solid content is about 15%.

Expancel DU — Dry, unexpanded microspheres

Expancel DU  is used in products where no water can be added, for example in industrial nonwoven textiles to improve bulk and thickness. Heat is needed in the process to cause expansion of the microspheres in the product.

Expancel DE — Dry, expanded microspheres

Expancel DE  is, among other areas, used in car underbody coatings to reduce weight.

Expancel SL — Slurry, microspheres dispersed in water

Expancel SL is a dispersion of unexpanded microspheres in water. The product is used where it is important that the product is extremely easy to disperse. For example, Expancel SL can be used in boxboard or fine paper to improve bulk and stiffness. Heat is needed in the process to cause expansion of the microspheres in the product.

Expancel MB — Masterbatch, microspheres mixed with a carrier

Expancel MB is used in thermoplastic applications to improve dispersion of the microspheres. It is Expancel DU mixed with a carrier. Heat is needed to cause expansion of the microspheres in the product.
