WACKER HDK T 30 Fumed Silica is a hydrophilic fumed silica produced by flame hydrolysis of volatile silcon compounds. WACKER HDK T 30 is pure, X-ray amorphous silicon dioxide (SiO2).
* Reinforcing filler for silicone rubber with very good mechanical properties
* Thickener and very effective thixotropic agent in liquid systems, polyester, PVC plastisols, paints and lacquers |
