Silane coated fine ATH application in submarine cable

Silane has good hydrophobicity, and silane-coated aluminum hydroxide is very suitable for use in the sheath of submersible cables to enhance water resistance and increase service life.In addition, after silane modification, the binding ability of aluminum hydroxide and resin is higher, which is more conducive to the increase of the mechanical properties of the cable.

The Surface Treatment of fine Aluminum Hydroxide

1. The purposes of surface modification Aluminum hydroxide is an inorganic filler,it is different in physical form and chemical structure from polymers, so the affinity between them is very low. In order to change its surface activity, surface coating treatment is generally carried out by adding a suitable large surfactant or coupling agent to achieve
