An Overview of the Applications of Plastic Blasting Media

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.

Plastic Media Blasting Applications

Figure 1. Plastic media blasting for automotive restoration.

Plastic media is commonly used to remove paint from cars, trucks, airplanes, boats, trains, helicopters, components and parts.

In contrast, PMB is an effective method for stripping all types of metals. It removes all or a part of a cured powder coating from the surface of a part without causing any damage. Figure 2 shows the PMB process used for removing powder coatings from components.

Aviation Paint Removal and Aircraft Maintenance

Composition Materials Plasti-Grit^® Plastic Blast Media is a preferred media for carefully removing paint from military and commercial jets and airplanes, and in aircraft maintenance operations throughout the world. Plastic Media Type V Acrylic is used on composite and aluminum aircraft skins, and also for blasting delicate parts. Plastic Media Type II Urea is used on tougher aluminum aircraft parts and landing gear. Type VI Clear-Cut is effective on composites and aluminum.

For more than 30 years, Composition Materials has manufactured Acrylic, Urea and Clear- Cut Plastic Blast Media capable of meeting the Military specification requirements for MIL-P-85891A, approved for use by the U.S. Army, Navy and Air Force. A number of private and commercial jet companies request Mil-Spec grade Plasti-Grit Plastic Blast Media for aircraft maintenance and aviation paint stripping operations.
