OliveCore

OliveCore

OliveCore (OSF) products are technological biofillers derived from olive pits, a residue from olive pomace processing. Its lignocellulosic composition, particularly rich in lignin, provides OliveCore with high density, low water absorption, and excellent chemical stability. These characteristics make it ideal for applications requiring surface hardness, resistance to external agents, and low dustiness.
