Even with relatively small dosages of Expancel added, the need for binder or other heavier fillers is reduced. This allows you to save on costs of raw materials and at the same time – enhance the properties of the substrates.
The closed cell structure of the microspheres not only puts you in control when adding volume, it creates and maintains an internal pressure during production. This results in optimal filling, low shrinkage and improved surface appearances with anti-slip properties, improved hand and matting. The internal pressure in tandem with the softening of the microspheres also allows for brilliant adhesion which is an ideal circumstance for sandwich constructions.
With it's low density, the microspheres equip your final product with superior insulation. They will also increase bulk and thickness as well as dimensional stability.
Expancel can be used in a wide variety of binder systems which are applied on the substrate, either by impregnation, coating, spraying or lamination.
