SIDISTAR® T, - the Additive with a Difference

A spherically-shaped amorphous silicon dioxide, which has been specially designed for polymer applications. Production under strict quality control assures a material with an average primary particle size of 150 nm. The nature of the material allows excellent dispersion down into primary particles in the polymer matrix.

 

Depending on the polymer use, SIDISTAR® T offers several advantages, which are further explained in our technical bulletins. SIDISTAR® T offers:

 

·         Foam blowing agent cell nucleation

·         Reduced plate-out

·         Flame retardancy synergist

·         Greater stiffness

·         Improved melt flow

·         Improved surface finish

·         Improved melt strength

·         Improved dryblend flow

·         Impact strength

·         Improved economy through faster processing

 

In short, SIDISTAR® T is your route to increased savings.

 

 

Dispersion into primary particles

 

SIDISTAR® T is a unique type of amorphous silicon dioxide. In the mixing process it improves the dispersion of all compound ingredients, leading to well-balanced physical properties in the final product. Being itself dispersed as primary spherical particles, it reduces internal friction and allows higher extrusion or injection speed as the result of better melt flow and therefore significant cost savings.

Products containing SIDISTAR® T will have improved processability, increased flame retardancy, greater stiffness and improved surface finish. In foamed PVC SIDISTAR® T particles are a nucleating site for the blowing agent. Dispersion down to primary particles within the matrix enables a very fine cell formation, resulting in a reduction of high molecular weight processing aid and therefore much reduced raw material costs. SIDISTAR® offers new opportunities for compound development, covering areas of properties not achievable with existing formulations.
