Pumice Grit 40 mesh

Why 40 Mesh Pumice Grit for Industrial Blasting

At 40 mesh, pumice particles are fine enough to produce a uniform satin finish yet aggressive enough to remove light oxides, carbon deposits, and surface contaminants. The mineral's natural angularity provides a gentle scrubbing action that preserves dimensional tolerances on soft metals, plastics, and composites. Unlike heavier mineral or metallic abrasives, pumice generates minimal impact stress, reducing the risk of thin-wall distortion.

Performance and Process Compatibility

This grade is compatible with standard suction and pressure-blast systems when operated at moderate air pressures. Because pumice is friable, it fractures on impact to expose fresh cutting edges, maintaining a consistent surface profile throughout the blast cycle. The low specific gravity (typically 0.8–1.2) demands careful media metering and dust-collection adjustment, but it also means less mechanical load on blast equipment and easier manual handling. Operators report excellent results on aluminium castings, fibreglass moulds, electronic components, and architectural restoration projects where substrate preservation is critical.

Pack Options and Supply Chain

SPA2Z offers flexible packaging to support both trial runs and full-scale production:

• 25 kg bag — convenient for small-batch work or sampling
• 50 kg bag — standard for regular blasting operations
• 1 ton jumbo bag — ideal for high-consumption facilities
• Bulk tote / drum pack — available on request for export or automated feed systems

We help buyers match the right pack size to their consumption rate, storage space, and freight economics. Minimum order quantities are flexible and confirmed at quotation stage based on your location and pack choice.
