Elasticity
by Expancel microspheres
You have a product showing an elastic behaviour. You want to reduce the weight of the product. Adding Expancel DE or Expancel WE will help you. Thanks to the very thin shell of the expanded microspheres they are elastic in character and behaviour. So in the process of reducing the weight of your product - the elasticity is completely retained.
If you add a very small amount of Expancel, it will improve the thermal shock resistance of a cultured marble bathtub.
