Product Information

Denka Fused Silica is an amorphous (noncrystalline) silica that is spherically shaped. It is made by melting high quality pure silica under high temperature. Fused silica has the lowest thermal expansion coefficient of all industrial materials. It has excellent thermal and chemical stability.

In addition, it has other attractive characteristics such as high electric insulation resistance and low dielectric constant. Our spherical fused silica filler offers excellent flowability and adaptability to varied particle distribution, thus leading to a surge in the world’s demand for our product. It also boosts high content filling in various resins and good moldability, making it suitable for use across a wide range of applications.

Applications

Filler for semiconductor encapsulating materials and Filler for various types of resins.
