Casasil Silicas
High-Purity Silicas for Reinforcement & Barrier Performance
Our fumed and precipitated silicas deliver powerful performance across rubber, plastics, coatings, and adhesives—enhancing viscosity control, reinforcement, anti-settling, and barrier properties in demanding applications.
Reinforcement
High-purity silicas improve tensile strength, stiffness, and durability in polymers and rubber compounds, supporting longer service life and improved mechanical performance.
Stability
By tuning rheology and flow behaviour, these silicas provide reliable viscosity control and anti-settling performance, helping to maintain uniform, stable formulations during storage and use.
Barrier Performance
Silica’s fine particle structure helps reduce permeability to gases and moisture, enabling superior barrier performance and longer-lasting protection in films, coatings, and sealants.
Cost-Effective Supply
With competitive pricing, multiple technology options and reliable global availability, our silica solutions offer a practical, scalable route to upgrading existing formulations.
