Dental Sandblasting White Fused Alumina 250-500μm
Dental Sandblasting White Fused Alumina with a particle size of 250-500μm is a high-performance, medical-grade abrasive specifically developed for dental prosthetics sandblasting, including dentures, crowns, bridges, and orthodontic appliances. Made from high-purity fused alumina through advanced electric melting and precision sieving processes, this product meets strict dental industry standards, ensuring safety, consistency, and excellent performance in dental surface treatment.
With a precisely controlled particle size range of 250-500μm (equivalent to 35-60 mesh), it provides optimal abrasive power to effectively remove stains, oxides, and residual debris from the surface of dental prosthetics without causing scratches or damage to the substrate. Its uniform particle shape and high hardness (Mohs hardness 9) ensure consistent sandblasting results, creating a clean, rough surface that enhances the adhesion of denture base materials, glazes, and adhesives, thereby improving the durability and fit of dental prosthetics.
This white fused alumina features high purity (Al₂O₃ ≥ 99.5%), low impurity content, and excellent chemical stability, which is non-toxic, non-irritating, and compatible with dental materials. It is resistant to chemical corrosion and high temperatures, maintaining its performance during the sandblasting process and ensuring no contamination of dental prosthetics. Suitable for both manual and automatic dental sandblasting equipment, it is easy to disperse and clean, reducing operational complexity for dental laboratories and manufacturers.
As a professional dental abrasive, it is widely used in dental prosthetics processing, helping to produce high-quality, biocompatible dental products that meet the strict requirements of dental clinics and patients.
