hydrophobic fumed silica for silicone rubber

Hydrophobic fumed silica which is produced by hydrophilic fumed silica after chemical post-treatment with Polydimethylsiloxane/ PDMS. It’s widely used in silicone rubber, coatings, inks, adhesives, sealants, lubricants, cable gel, vinyl ester resin and powder coating industries. It has good thickening & thixotropy properties, and stability in epoxy resin system products, high loading enables it great reinforce performance for polymers.
