Silica cas 14464-46-1 Usage

Precision Investment Casting & Dental Investment Materials (Core Application):
- Investment Casting: Applied in high-precision mold shell formulations for aerospace and industrial metallurgy due to its predictable thermal expansion characteristics.
- Dental Prosthetics: Serves as a vital expansion-compensating refractory filler in dental casting flux and crown/bridge investment compounds.
Specialty Coatings, Adhesives & Polymer Fillers: Owing to its low refractive index (1.48), it acts as a transparent, anti-scratch functional extender in clear wood coatings, powder coatings, epoxy encapsulants, and engineering thermoplastics. This product can replace glass beads as reflective paint, which can enhance the anti-slip property and improve the reflective properties of the paint. It is suitable for automotive base materials and various paints and paint fillers.
Refractory Ceramics & Silicone Rubber: Formulated into thermal-shock-resistant ceramics, refractory linings, and reinforcing fillers for high-performance silicone elastomers.
