Plastic Blasting Media – Overview, Advantages and Applications

Plasti-Grit® plastic blast media is made from 100% recycled materials. This eco-friendly abrasive is used in industrial cleaning and paint removal processes. Plastic media abrasives effuiently strip epoxies, powder coatings, primers, paints and coatings from steel, hard metals, brass, aluminum, plastics, composites and fiberglass.

Plasti-Grit® is manufactured in 5 grades of hardness (Urea, Melamine, Clear-Cut®, Acrylic and Polyester) in all standard sizes and meets MIL-P-85981.

Blasting with Plastic Media prevents damage to delicate substrates and is therefore an excellent alternative to hard abrasives as well as chemical stripping. Plastic abrasives can be reclaimed many times, offering excellent cost benefits.
