Amorphous Silicon Dioxide in Chemical Compounds

As a key component in polymer compounding, Elkem’s Sidistar® improves dispersion in the mixing process. It reduces internal friction and allows for higher extrusion speeds. As more industries move to non-halogenated flame retardant systems, Sidistar is critical for meeting stricter flame retardant standards without using halogen compounds.

Because of its spherical, “ball-bearing” shape, Sidistar functions as a viscosity modifier without detracting from the finished compound’s physical properties. Its design and dispersion capabilities ensure a well-balanced final product. It’s widely used as a processing aid, flame retardant and performance additive.

Elkem Sidistar Silicon Dioxide
We supply several variations of Elkem’s silicon dioxide additives, including the Sidistar R 300, 320 and T120U. Keep reading for more information or contact a chemicals expert today!

Sidistar® R 300 & 320

The Sidistar R series is ideal for use in rubber compounds. Applications include flame-retardant cable compounds, anti-vibration parts, hoses, roofing membranes and conveyor belts.

Sidistar T120U (Undensified)

SIDISTAR T120U is a specially designed, light-colored process modifier featuring spherical particles of amorphous silicon dioxide. Its design allows for excellent dispersion of particles in the polymer matrix. This improved dispersion results in higher extrusion/injection speeds and a smoother surface of the end product. SIDISTAR T120U is available in an undensified form.
