Pumice Grit 220 mesh

Understanding 220 Mesh Pumice for Industrial Blasting

Pumice is a naturally occurring volcanic glass formed during explosive eruptions. Its highly porous, frothy structure gives it a low bulk density and a unique, angular particle shape. When crushed and graded to 220 mesh, the resulting grit is exceptionally fine, producing a smooth, satin-like finish on surfaces. Unlike harder abrasives like aluminum oxide or garnet, pumice grit removes contaminants, light oxidation, and surface deposits without significantly altering the substrate profile.

This makes 220 mesh pumice grit a preferred choice for cleaning soft metals like aluminum and brass, restoring historical artifacts, deburring delicate electronic components, and preparing surfaces for non-stick coatings or specialized paints. Its lightweight nature also reduces operator fatigue in manual blasting operations and minimizes media embedment issues.

Key Features and Performance Benefits

• Low Hardness (Mohs ~6): Cleans effectively without etching or pitting sensitive base materials.
• Angular Particle Shape: Provides a mild scrubbing action for efficient contaminant removal.
• Low Bulk Density: Lightweight media reduces consumption by weight and is easier to handle in large volumes.
• Inert and Non-Toxic: A naturally safe mineral, free from crystalline silica hazards associated with sand.
• Excellent for Delicate Work: Ideal for aluminum, brass, fiberglass, plastics, and thin-gauge metals.

Typical Industrial Applications

This fine-grade pumice is specified across a range of industries where surface preservation is critical. Common applications include:

• Automotive Restoration: Cleaning aluminum engine parts, carburetors, and soft alloy wheels without dimensional changes.
• Aerospace MRO: Stripping coatings from composite materials and delicate airframe components.
• Electronics Manufacturing: Deburring circuit boards and cleaning delicate connectors.
• Cultural Heritage: Gentle cleaning of stone, brick, and metal artifacts in historical restoration projects.
• General Manufacturing: Preparing surfaces for bonding, painting, or PTFE coating applications.
