Made from borosilicate glass, SiLibeads AIR hollow microspheres are filling materials, allowing the modification of the physical properties of thermoplastics and duroplastics.
These materials are chemically very stable and are characterized by a very low density and high compressive strength. With a density of 0.15 to 1 g/cm3, they have a compressive strength of 2 to 124 MPa.
SiLibeads AIR microspheres are used in various applications: automotive as a PVC-based plastisol sealant, filling material for weight reduction in composite materials such as lightweight concrete or cement, thermal insulation in coatings, material for decorative effects in wall paintings, etc.
