Type III Plastic Blast Media — 20 Mesh Grade
This 20 mesh grade offers a balanced particle size that delivers effective coating removal rates while maintaining the fine surface finish required for sensitive components. The angular particle shape provides a controlled cutting action, and the relatively low hardness (Mohs 3.0–4.0) ensures the underlying substrate is preserved. It is chemically inert, silica-free, and generates low dust compared to mineral abrasives.
Performance Characteristics
- Substrate-safe: Will not warp thin metal panels, erode composite matrices, or round sharp edges.
- Controlled aggression: Strips paint and light rust without removing anodized layers or plating.
- Recyclable: Can be reused multiple times in controlled blasting environments, lowering media consumption cost per square foot.
- Low embedment risk: Leaves minimal residue, reducing pre-coating cleanup.
Common Process Compatibility
Plastic Media Type III is suitable for both suction and direct-pressure dry blasting systems. It is not recommended for wet blasting or wheel-blast machines. Typical operating pressures range from 2 to 4 bar (30–60 PSI), with nozzle distance adjusted to the substrate. Always conduct a first-article test to confirm cycle time and finish.
