Lineup
Low-soda Alumina (AL Series)
The AL series is α-alumina which has reduced soda content, controlled by our proprietary technology. Extra fine alumina particles are used as an ingredient in resins alongside coarse ingredients.
Features
- Fine particles (submicron to 3 μm)
- Low Soda (≤0.10 ％)
- Good dispersibility
- Thixotropic properties
Roundish Alumina (AS Series)
The AS series is a single-grained alumina with less crystal edges. Due to its large particle size and broad particle size distribution, it enables the production of compounds with excellent fluidity and stability.
Features
- Coarse particles (9 - 36 μm)
- High fillability
- Stability
- High thermal conductivity
Spherical Alumina (Alunabeads CB Series)
The CB series is a spherical single-grained alumina. CB produces compounds with high filling rates and good viscosity. The CB series is featuring various particle sizes and particle distributions to meet your requirements.
Features
- Fine to coarse grains (2 - 100 μm)
- A wide range of particle sizes
- Low specific surface area
- High filling capacity
Hexagonal Boron Nitride (SHOBN UHP Series)
SHOBN, our UHP series is a high purity crystalized Hexagonal Boron Nitride. SHOBN has excellent thermal conductivity, high thermal stability, corrosion resistance, and good electrical characteristics (high electrical insulation, low dielectric constant).
Features
- High purity
- Low hardness, low specific gravity
- High thermal conductivity
- High insulation properties & low dielectric constant
