For industrial, chemical, and manufacturing applications requiring an exceptionally clean, graded aggregate, Sunstate Dried Silica Sand provides a high-purity source of silicon dioxide with a controlled particle size distribution. The sand is dried and processed to ensure a consistent grading between 0.105mm and 0.425mm, making it suitable for specialized blending, chemical processing, and technical trade applications.
What it does
Sunstate Dried Silica Sand acts as a pure, inert filler and aggregate. The material is graded using British Standard Sieves, ensuring that at least 95% of the particles pass through a 0.425mm aperture while at least 95% are retained on a 0.105mm aperture. This precise particle size distribution (PSD) prevents unwanted fines or oversized grains from compromising your mix design or application matrix.
With a silicon dioxide (SiO2) content exceeding 99%, this silica sand minimizes chemical impurities that can cause discoloration, unwanted reactions, or binder interference in sensitive formulations. Particle size testing is verified under Sunstate Sands Standard Operating Procedure SOP-LAB 03a.
Numbers that matter
-
>99% SiO2: High chemical purity limits trace contaminants and ensures compatibility with sensitive binders and chemical processes.
-
Minimum 95% Passing 0.425mm: Establishes the upper limit of the particle size envelope to prevent oversized grains in thin-layer applications.
-
Minimum 95% Retained on 0.105mm: Establishes the lower limit of the particle size envelope to prevent excessive dust and fines from affecting binder demand.
-
<0.030% Fe2O3: Low iron oxide content prevents rust staining and helps maintain colour stability in architectural and clear binder systems.
