Description

Spherical white fused alumina is high sphericity alumina powder from unique high tempreture melting technology.

Spherical white fused alumina can provide high thermal conductivity and improvement of the surface hardness of the various plastic or rubbers by filling them. Low ionic impurity type is also available. This can be used in the electronic material field where reliability is required (Particle diametera: D50: 3-50μm)

Easily filled with high content to various types of resin and rubbers, and can also control wear in kneading machines or molds compared with irregular-shaped fillers, the particles distribution can be adjusted according to use.
