Plastic Media Type II 36 mesh

Understanding Plastic Media Type II 36 Mesh

Type II plastic media is a thermoset polyester-based abrasive, characterized by its angular, strip-like particle shape. The 36 mesh designation indicates a medium-coarse particle size distribution, optimized for rapid coating removal with a controlled profile. Unlike mineral abrasives, it has a low hardness (typically 3.0–4.0 on the Mohs scale), which allows it to strip paints, primers, and coatings without etching, warping, or removing the base material.

This makes it the preferred choice in aerospace, automotive restoration, and composite manufacturing. It is specifically formulated to be free of free silica, minimizing health hazards and making it compliant with stringent environmental and safety regulations for dry stripping operations.

Key Features and Performance Benefits

• Substrate-Safe Stripping: Removes coatings from aluminum, fiberglass, composites, and thin-gauge steel without surface distortion or metal loss.
• High Recyclability: The durable thermoset formulation resists breakdown, allowing for multiple cycles in blast cabinets and recovery systems, lowering your media consumption cost.
• Consistent 36 Mesh Cut: Precisely graded to ensure uniform particle distribution, delivering a predictable surface finish and consistent strip rate across large surface areas.
• Dust-Free Operation: Generates minimal dust compared to mineral abrasives, improving operator visibility and reducing particulate containment requirements.

Industrial Applications

This 36 mesh grade is selected for applications requiring a balance of speed and control. Common uses include:

• Aerospace MRO: Stripping paint and primers from aircraft skins, radomes, and control surfaces without damaging the underlying aluminum or composite structure.
• Automotive Restoration: Removing body filler, paint, and rust from classic car panels and fiberglass bodies without heat warping.
• Composite Manufacturing: Surface preparation of fiberglass and carbon fiber parts for bonding or re-coating.
• Mold Cleaning: Removing release agents, rubber residue, and build-up from injection molds and tire molds without altering mold dimensions.
• Marine Maintenance: Stripping anti-fouling paint and gel coat from boat hulls without scratching the fiberglass substrate.

Selection and Handling Guidance

For optimal results, use Plastic Media Type II 36 mesh in pneumatic suction or direct-pressure blast systems at a nozzle pressure of 2–4 bar (30–60 PSI). Maintain a nozzle-to-workpiece distance of 12–18 inches and an impact angle of 60–90 degrees. Always screen reclaimed media to remove fines and contaminants before reuse. Store in a dry environment to prevent moisture absorption, which can affect flowability.
