Expancel DE, dry expanded microspheres

Contact and services

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.

Product-enhancing benefits of Expancel DE

Reduces weight across various applications
Reduces density in polyester putties (1% Expancel = 45% reduction)
Excellent adhesion between polyester resin and microspheres
Easier to sand and no pinholes (e.g. polyester putties, model making board)
Low water absorption
Higher resistance to thermal shock
Highly elastic, shock absorbent addition for quality cultured marble and lightweight foam
Saves costs on binder/resin and other raw material
Improves thermal insulation, sound blocking and vibration damping
Reduces costs for model making board and sealants
High resilience for printing blankets
