Z-sil® is a high purity, high quality natural crystalline silica that is available exclusively through zigma international. This ground silica sand is inherently inert, white, bright, has low moisture and is at least 98+.
z-sil is available in uniform size distributions. They feature unmatched fineness and consistency of particle size due to a special processing technique developed by zigma international.
special processing techniques assure controlled particle size distribution, which means elimination of excessive coarse and fine particles. These properties, combined with inertness and inherently low cost, make z-sil® the best quality filler/extender for a range of applicationsincluding paints and coatings, sealants, silicone rubber and epoxy.
zigma pure silica's whole grain, unground sand is available in a wide variety of grain shapes and size distributions to meet any application requirement. At each mining location, raw material is processed, screened and graded to assure the finest quality sand.1. Glass sands
- zigma international provides a wide range of high purity, low iron, pure silica sands for the glass industry. Products that require silica sands include: glass containers, flat glass, fiber glass insulation, textile fiber glass and a variety of other specialty glass products. To effectively serve the glass industry we

must closely monitor screen sizing for consistentparticle size and distribution. By meeting these strict requirements for quality and consistency, ZIGMA INTERNATIONAL enables its customers to realize maximum production efficiencies and cost savings.
Our ground and fine-ground (micronized) silicas, white silica sand, superior silica sand are naturally bright white, low in moisture, and chemically inert. They contain at least 99.5% pure SiO2 and areused in many different products requiring rigid control of physical and chemical properties.
Z-SIL ground silica, available in more than ten uniform grades, ranging from 120 to 400 mesh in topsize.
micronized silica, available in five grades, ranging from 40 down to 5 microns in topsize.2. Foundry sands
ZIGMA INTERNATIONAL supplies over many grades of round, angular and sub-angular sands to the foundry industry for molding and coremaking applications.Because of the high silica content and our ability to meet a wide range of sand specifications, we are helping foundry customer's produce high integrity castings, free of defects and with superior surface finishes.
Sands from ZIGMA INTERNATIONAL are helping foundry customers compete in a world market which demands high quality castings at competitive prices.
At ZIGMA INTERNATIONAL we Produce foundry sands close to our customer's plants and in the grain shapes and sizes required.
Equip, maintain and staff these plants to produce the highest quality sand possible.
Provide research and development facilities staffed with experienced technical service representatives to help foundries better utilize these sands.3 .Building Products-
Zigma International mines and produces whole grain and ground silica and kaolin clays for the building products industry.
End uses range from asphalt sealants and shingles to mortars, grouts, clay bricks, fiber- cement panels to pool filtration media and ASTM testing sand.
