Plastic Media Type III 100 mesh

Understanding Plastic Media Type III 100 Mesh

Type III plastic media is formulated from urea resin, making it softer and less dense than Type II (melamine) media. The 100 mesh designation refers to a fine particle size distribution, typically passing through a 100-mesh screen (approximately 149 microns). This combination of soft chemistry and fine particle size delivers a gentle yet effective stripping action.

The angular shape of the particles provides a controlled cutting edge that lifts coatings cleanly, while the low hardness (typically Mohs 3.0–4.0) prevents substrate erosion. This makes it exceptionally safe for use on fiberglass, carbon fiber composites, thin-gauge aluminum, and magnesium alloys.

Key Features and Performance Benefits

• Substrate-safe stripping: Removes paint, primers, and powder coatings without etching, pitting, or warping sensitive base materials.
• High recyclability: Urea plastic media withstands multiple impact cycles, typically offering 8–15 reuses before particle breakdown, significantly reducing media consumption costs.
• Dust-minimized operation: Generates less friable dust compared to mineral abrasives, improving operator visibility and reducing cleanup time in enclosed blasting environments.
• Consistent finish profile: The uniform 100 mesh particle distribution produces a predictable anchor pattern, ideal for immediate recoating without additional surface profiling.

Typical Applications

This fine-grade media is specified across industries where precision and surface integrity are paramount. Common applications include:

• Aerospace MRO: Stripping paint from radomes, control surfaces, and composite fuselage panels without damaging the resin matrix.
• Automotive Restoration: Removing single-stage and clear-coat paints from fiberglass body panels, SMC components, and plastic bumpers.
• Composite Manufacturing: Preparing carbon fiber and fiberglass layups for secondary bonding or cosmetic refinishing.
• Electronics Enclosures: Cleaning thin-walled aluminum and magnesium housings without deformation.

Selection and Handling Guidance

For optimal results, use Plastic Media Type III 100 mesh in low-pressure (2–4 bar / 30–60 PSI) suction or direct-pressure blast systems. Maintain a nozzle distance of 30–45 cm from the workpiece and use a 60–90 degree angle of attack for coating removal. Always conduct a first-article test on a scrap part to validate cycle time and surface finish before processing production components.

Store media in a dry, covered environment to prevent moisture absorption, which can cause clumping and inconsistent feed rates. When loading hoppers, screen reclaimed media to remove coarse contaminants that could block nozzles or damage sensitive substrates.
