Pumice Grit 180 mesh

Lightweight Cleaning with 180 Mesh Pumice

The primary advantage of 180 mesh pumice grit is its ability to clean and finish surfaces without the aggressive impact of heavier abrasives like aluminum oxide or garnet. Its friable nature means the particles fracture upon impact, creating fresh, sharp edges that gently scrub away contaminants, light oxides, and coatings. This action produces a uniform, satin-like surface finish that is difficult to achieve with other media.

Because it is a naturally occurring mineral with low free-silica content, pumice is often selected as a safer alternative to silica sand in many blasting operations. Its low specific gravity also means less material by weight is needed to fill a blast pot, and it generates less kinetic energy, giving the operator greater control over the process.

Key Features and Benefits

• Controlled, gentle cutting action: Cleans without dimensional change to the substrate, making it safe for precision parts and soft metals like aluminum and brass.
• Uniform 180 mesh particle distribution: Ensures a consistent surface finish across the entire workpiece, critical for aesthetic and pre-plating applications.
• Low-density, lightweight media: Reduces operator fatigue and allows for effective blasting at lower air pressures, saving on energy and equipment wear.
• Friable, self-sharpening particles: Continuously exposes new cutting edges for a consistent cleaning rate throughout the media's life cycle.
• Versatile application method: Suitable for use in standard suction and pressure blast cabinets, as well as wet blasting systems.

Industrial Applications

The 180 mesh grade is a specialized tool for fine finishing. It is not intended for heavy rust or mill scale removal. Its value is in precision work.

• Electronics and PCB Manufacturing: Used for micro-etching and cleaning delicate circuit boards and electronic connectors prior to conformal coating or bonding.
• Textile and Denim Finishing: Applied in controlled blasting systems to create a soft, worn-in look on denim and other fabrics without tearing the material.
• Soft Metal Finishing: Ideal for achieving a uniform matte finish on aluminum, brass, and copper components before anodizing, plating, or painting.
• Mold and Tool Cleaning: Effectively removes light residue, release agents, and carbon deposits from injection molds and tooling without altering critical dimensions.
• Glass Etching: Used to create a frosted, decorative finish on glass surfaces where a smooth, even appearance is required.

Selection and Handling Guidance

To get the best results from 180 mesh pumice grit, proper setup is essential. We recommend starting with a blasting pressure between 2-4 bar (30-60 PSI) and adjusting based on the substrate and desired finish. The nozzle-to-part distance should be greater than what is used for heavier abrasives to allow the lightweight particles to achieve effective velocity.

This media is typically used in a suction blast cabinet or a pressure pot system with a large-diameter hose to prevent clogging. Due to its friable nature, pumice will generate fine dust; a properly functioning dust collector is mandatory. While it can be recycled, its breakdown rate is higher than that of tougher media, so operators should monitor the working mix and add fresh grit regularly to maintain the 180-mesh cutting action.
