Plastic Media Type III 50 mesh

Understanding Plastic Media Type III 50 Mesh

Type III plastic media is formulated to be softer than Type I or Type II alternatives, making it the definitive choice for removing paint and light coatings from aluminum, composites, fiberglass, and thin-gauge metals. The 50 mesh particle size offers a balanced profile, providing sufficient impact energy to strip coatings efficiently while preserving the integrity of the underlying surface.

This media is widely used in aerospace, automotive restoration, and marine maintenance, where substrate preservation is critical. Its angular shape promotes a consistent, even finish, and its low hardness rating minimizes the risk of embedding or surface contamination.

Key Features and Operational Benefits

• Substrate-Safe Stripping: Specifically designed to remove thin coatings without damaging soft or heat-sensitive base materials.
• Controlled Aggressiveness: The 50 mesh particle size delivers a uniform profile, ideal for achieving a smooth, paint-ready surface.
• Low Dust Generation: Compared to mineral abrasives, plastic media produces less friable dust, improving operator visibility and reducing cleanup time.
• Recyclability: The media can be reclaimed and reused multiple times in closed-loop blasting systems, lowering overall media consumption and cost per square foot.
• Versatile Packing: Supplied in 25 kg bags, 50 kg bags, 1-ton jumbo bags, bulk totes, and drum packs to match your operational scale.

Industrial Applications

This 50 mesh Type III media is specified in applications where coating thickness is minimal and substrate hardness is low. Typical uses include:

• Aerospace MRO: Stripping paint from aircraft skins, control surfaces, and composite radomes without etching or warping.
• Automotive Restoration: Removing primer and paint from fiberglass body panels, bumpers, and aluminum engine components.
• Marine Maintenance: Cleaning gelcoat and anti-fouling paint from boat hulls without damaging the underlying fiberglass.
• Electronics Manufacturing: Deflashing and cleaning delicate molded plastic parts and connectors.

Selection and Handling Guidance

To achieve optimal results, use this media in a pressure blast or suction blast cabinet with adjustable air pressure. Start with a low pressure setting (typically 20-40 PSI) and increase only as needed. Ensure the media is dry and free-flowing before loading. For closed-loop systems, implement proper air-wash separation to remove spent fines and maintain consistent particle size distribution.

Procurement teams should specify the exact mesh size and Type III grade when requesting a quote to ensure compatibility with their existing blasting parameters and substrate requirements.
