Plastic blast media particle size influences the rate of coating removal and degree of substrate impact.
Larger particle sizes increase stripping efficiency, while smaller particles provide greater control and reduced surface stress.

Particle size selection should be matched to the substrate material, coating thickness, and acceptable surface impact.
Softer substrates and thin skins typically require finer particle sizes to minimise damage.
