Significantly Reduce the Dielectric Constant of the System


Hollow Silica has the characteristics of low specific gravity, high sphericity, and low dielectric constant. It is especially suitable for use in high-frequency high-speed CCL (copper clad laminates) for 5G communication base stations, which can significantly reduce the dielectric constant of the system.


Inorganic nano-powder flame retardant, suitable for low-smoke halogen-free cable materials, can effectively reduce the total heat release and heat release peak of cable materials during combustion test; can significantly reduce the smoke density during combustion , improve light transmittance.

In the EVA system, 60~65% of the added amount can pass the B1 flame retardant grade in GB31247.


Chemically Porous Silica with low specific gravity, high specific surface area, high oil absorption and narrow particle size distribution. It is especially suitable for the opening agent of BOPA, BOPET, BOPP and other films. Generally, the addition amount of 1%~2% can significantly improve the opening and smoothing performance of the film.
