Core Product Performance
The core performance of spherical silica micropowder focuses on "high efficiency adaptation and stable reliability", and the key performance indicators are as follows:
High Fluidity
The spherical particle structure reduces the frictional resistance between particles. Compared with angular powder, the fluidity is greatly improved, facilitating mixing, filling and molding in subsequent processing;
High Fillability
Spherical particles are closely arranged, enabling high-proportion filling in various matrix materials, which can not only reduce product production costs but also effectively improve the comprehensive performance of products;
Low Dielectric Performance
It has excellent insulation performance, with a low and stable dielectric constant, adapting to the high-end requirements of insulation materials in the electronic and electrical fields, and can reduce signal interference;
Low Expansion
It has a low coefficient of thermal expansion, which can effectively reduce the shrinkage and deformation of products in high and low temperature environments, and improve the dimensional stability and service life of products.
