Precipitated Silica

We are proud to represent Glassven C.A. and their broad line of RubberSil Precipitated Silica and Synthetic Sodium Aluminum Silicates.

We maintain an inventory of RubberSil Precipitated Silica and Silicates at warehouse locations coast to coast ready for immediate shipment in the quantities you need for your business.

Tests have shown that our precipitated silica is comparable in performance and processing capabilities to our competitors' -- see the charts below for specific comparisons.

Glassven C.A. offers the right RubberSil product for formulators and compounders to provide the best balance of physical properties and processability.
