GRANUSIL® Mineral Fillers

A fine mesh silica sand which increases thermal conductivity

GRANUSIL Mineral Fillers, manufactured by Unimin Cororation, is a fine mesh silica sand that is mixed with bentonite grout products to increase their thermal conductivity properties.  Not only does this sand have excellent thermal enhancement properties, it maintains good pumping characteristics when mixed with the bentonite grout .

This silica sand is produced from high purity industrial quartz sands for a wide variety of industrial and contractor mixed applications which need a reliable silica contribution or require a chemically inert structural filler. Consistently uniform grain shapes and particle size distributions offer excellent placement, compaction and mechanical properties. High silica content combined with low-level soluble ions, alkalis and alkaline oxides provide non-reactive service in most corrosive and exposed environments.

GRANUSIL is available in 4030 and a 5010 meshes and comes palletized in 64 – 50 lb bags made of plastic so the sand doesn’t absorb water at the job site.

As a service to our contractors, we calculate grout volumes and include an accurate project materials list in all our quotes. Our on-site warehouse is inventoried for on-demand shipping directly to your job site. For ease in handling, our products arrive at your specified location palletized and shrink wrapped.
