The FRILITE® Group differentiates between construction materials (give buildings basic shape and structure) and construction chemicals (used for connection, protection, sealing, etc.). As construction chemical products are mainly used in thin layers focusing on shape, mechanical strength and weight saving, the finest grades of FRILITE® hollow microspheres are the best choice. Already a relatively low mass fraction in a formulation can make a huge difference. The FRILITE® Group, as one of the few suppliers of hollow mineral microspheres, offers different types and grades (e.g. d10 and d90 values) to formulators in order to meet all standard requirements. The microspheres can also be produced with Topcut.
