Corn Cob Grit 120 mesh

Organic Abrasive for Precision Surface Preparation

Corn Cob Grit 120 mesh is classified as a soft, organic abrasive. It is derived from the woody ring of the corn cob, processed, and sieved to a consistent 120 mesh particle size. This fine grade is particularly effective for cleaning molds, dies, and tooling where metal surfaces must remain pristine and undamaged. Unlike harder mineral or metallic abrasives, corn cob grit absorbs contaminants and wipes surfaces clean without abrasively cutting the substrate.

Common processes include suction-fed and direct-pressure dry blasting. The material is free-flowing, low in dust when properly graded, and can often be recycled multiple times before breakdown, depending on the application and contaminant load.

Key Features and Benefits

• Non-damaging cleaning: Removes grease, carbon, and light oxides without etching or pitting metal molds and dies.
• Biodegradable and non-toxic: A safe, environmentally friendly alternative to chemical solvents and hard mineral abrasives.
• Low dust generation: Properly graded 120 mesh particles minimize airborne dust, improving operator visibility and safety.
• Reusable media: Can be cycled multiple times in contained blasting systems, reducing media consumption and waste.
• Versatile packing: Available in 25 kg bags, 50 kg bags, 1-ton jumbo bags, bulk totes, and drums to match your handling equipment and consumption rate.

Typical Applications

Corn Cob Grit 120 mesh is specified across a range of industries where gentle cleaning is paramount. It is widely used in the rubber and plastics industry for cleaning molds and extrusion dies. In the automotive and aerospace sectors, it is employed for degreasing and light surface preparation of delicate alloy components. Electronics manufacturers use it for deflashing and cleaning circuit boards and connectors without causing damage. It is also effective for cleaning wood surfaces and removing light coatings from fiberglass.

Selection and Handling Guidance

To achieve optimal results, ensure your blasting system is compatible with organic media. Corn cob grit is typically used at lower blast pressures (2–4 bar / 30–60 PSI) to prevent premature particle breakdown. The 120 mesh size is a fine grade; confirm that your dust collection system is rated for fine organic dust. Always store bags in a dry, covered area to prevent moisture absorption, which can cause clumping and flow issues in metering valves.
