Omyasphere 900 series are lightweight fillers based on hollow glass microspheres designed for polyurethane, silyl-modified polymers, and silicone adhesives & sealants.
These spherical, hermetic microspheres combine low density, high compressive strength, and brightness to enhance formulations.
They reduce weight, improve rheology, increase yield, and ease application while lowering transport emissions.
A case study shows that adding 4.7% Omyasphere 938 to oxime silicone sealant reduces density by 21% without compromising mechanical or rheological performance.
