Buy Industrial Silica (SFJ-MID) – Consistent Performance for Industry

SFJ-MID: The Industrial Silica for Consistent Performance

SFJ-MID is a high-purity and Industrial silica, sub-angular crystalline silica sand that is meticulously washed, dried, and screened to a precise particle size distribution. This product serves as the industrial workhorse for applications where consistency, thermal stability, and mechanical strength are paramount. With its tightly controlled grading and inert chemical nature, SFJ-MID provides predictable performance in foundry, construction, filtration, and general industrial applications, ensuring reliable outcomes and process efficiency.

Key Features & Benefits

• Consistent Particle Size Distribution: Tightly controlled grading ensures excellent uniformity, predictable packing density, and repeatable performance in any application.
• High Purity & Chemical Inertness (≥ 99.2% SiO₂): Guarantees superior performance under high temperatures and harsh chemical conditions, preventing unwanted reactions and ensuring product integrity.
• Optimal Sub-Angular Grain Shape: Provides an ideal balance between flowability and mechanical interlocking, creating a strong, stable matrix in mortars, grouts, and composites.
• High Thermal Stability: With a high fusion point, it is exceptionally suited for foundry molds and cores, resisting metal penetration and ensuring high-quality castings.
• Washed & Low in Fines: A multi-stage washing process removes clay, dust, and other impurities, resulting in a clean aggregate that improves binder efficiency and final product quality.
• Exceptional Hardness (7 Mohs): Delivers outstanding durability and resistance to abrasion and wear, making it ideal for high-traffic flooring and abrasive applications.

Primary Applications

• Foundry Molds & Cores: The industry silica standard for sand casting of both ferrous and non-ferrous metals.
• Water & Industrial Filtration: Used as a primary filtration media layer for removing suspended solids in potable water and industrial process water treatment.
• High-Performance Mortars, Grouts & Concrete: Acts as a structurally sound aggregate, improving strength, dimensional stability, and reducing shrinkage.
• Industrial & Resin Flooring: The aggregate of choice for trowel-down epoxy systems, broadcast floors, and polymer concrete.
• Abrasive Blasting Media: A cost-effective and efficient media for surface preparation and cleaning.
• Specialty Plasters & Renders: Provides body, texture, and reinforcement for decorative and functional wall finishes.
