Expancel dry, expanded microspheres have low density, extreme elasticity and low moisture absorption – giving you a magnificently beneficial ingredient for a wide range of applications. Used in products where no water can be added like cultured marble and model-making board to name a few, Expancel DE will reduce weight, improve workability and provide a highly resilient property.
