Plastic Media Type II 20 mesh

Thermoset Plastic Strip Media for Controlled Blasting

Plastic Media Type II is a thermoset, angular strip media formulated for aggressive yet substrate-safe blasting. The 20 mesh particle size is a versatile mid-range grade, suitable for removing tough coatings like powder coat, paint, and light rust from aluminum, fiberglass, composites, and other delicate metals. Unlike harder mineral abrasives, this plastic media deforms upon impact, transferring energy to the coating without eroding or warping the base material.

This media is commonly used in air blast systems, including pressure and suction cabinets, for applications where maintaining tight dimensional tolerances is critical. Its angular shape provides a consistent cutting edge, while its low hardness relative to metals ensures the substrate remains intact. Users can expect efficient stripping rates with minimal dust generation compared to more friable media types.

Key Features and Benefits

• Thermoset formulation: Resists softening and maintains particle integrity during high-energy blasting, allowing for multiple reuse cycles.
• Angular strip shape: Delivers a consistent, sharp cutting edge for fast coating removal without excessive embedment.
• Substrate-safe action: Low hardness protects aluminum, composites, and thin metals from warping, pitting, or erosion.
• Versatile 20 mesh grade: Balances stripping speed and surface finish, suitable for a wide range of industrial coating removal tasks.

Industrial Applications

Plastic Media Type II 20 mesh is specified across various industries for precision stripping and surface preparation. Common applications include:

• Aerospace & Aviation: Removing paint and coatings from aircraft skins, composite panels, and landing gear components without affecting anodized layers or clad surfaces.
• Automotive & Composites: Stripping paint from fiberglass body panels, bumpers, and carbon fiber parts without causing heat warping or fiber damage.
• Military & Defense: Depainting vehicles, munitions, and equipment where substrate integrity is paramount.
• General Manufacturing: Cleaning molds, removing powder coating from fixtures, and preparing surfaces for re-coating or bonding.

Selection and Handling Tips

To achieve optimal results with Plastic Media Type II 20 mesh, consider the following operational guidelines:

• Blast pressure: Start with a low pressure (2-4 bar / 30-60 PSI) and increase only as needed to prevent premature media breakdown.
• Nozzle distance: Maintain a consistent standoff distance of 12-18 inches to maximize stripping efficiency and media life.
• Recycling: This thermoset media is designed for multiple cycles. Implement proper media reclamation and classification to remove fines and maintain consistent particle size distribution.
• Storage: Store in a dry, covered area. Moisture absorption can affect flowability and blasting consistency.
