Plastic Abrasive 90 mesh

How 90 Mesh Plastic Abrasive Works

Unlike aggressive mineral or metallic abrasives that cut into the substrate, plastic abrasive media relies on a combination of particle hardness, angularity, and kinetic energy transfer. Upon impact, the sharp edges of the urea-formaldehyde particles fracture, absorbing energy and lifting the coating layer away from the base material. The 90 mesh size offers a fine, consistent particle distribution that produces a uniform surface finish with minimal embedment risk.

This makes it highly effective for stripping multi-layer coatings from aircraft skins, removing conformal coatings from electronic components, and cleaning molds without altering critical dimensions. The media can be recycled multiple times in controlled blasting environments, reducing overall consumption and waste.

Key Benefits for Industrial Buyers

• Substrate-safe stripping: Removes coatings without etching, pitting, or warping sensitive base materials like aluminum, brass, fiberglass, and carbon fiber composites.
• Controlled aggression: The 90 mesh grade delivers a fine finish suitable for precision applications where surface roughness (Ra) must be tightly controlled.
• Low dust generation: Urea plastic media produces less airborne dust compared to mineral abrasives, improving operator visibility and reducing containment requirements.
• Multiple recycling cycles: In pressure blast or suction blast systems with proper media reclamation, this abrasive can be reused 5–8 cycles before particle breakdown reduces effectiveness.
• Versatile pack options: Order in 25 kg bags, 50 kg bags, 1-ton jumbo bags, bulk totes, or drum packs to match your production volume and handling setup.

Typical Applications

Plastic Abrasive 90 mesh is specified across industries where substrate integrity is non-negotiable. Common use cases include aircraft component overhaul (stripping fuselage panels and landing gear parts), automotive restoration (removing body filler and paint from classic car panels), marine maintenance (cleaning fiberglass hulls and decks), and electronics manufacturing (de-flashing and conformal coating removal). It also serves mold cleaning operations in rubber and plastics processing, where aggressive media would damage polished cavity surfaces.

Selection and Process Guidance

For optimal results, operate this media at blast pressures between 2–4 bar (30–60 PSI) using a pressure blast or suction blast system. Higher pressures increase strip rate but reduce media life and may risk substrate damage on ultra-thin sections. Always test on a sample coupon before full-scale production. The 90 mesh grade is ideal when you need a fine finish and can accept a moderate strip rate; for faster stripping of thicker coatings, consider coarser grades like 20/30 or 30/40 mesh plastic abrasive.

Store media in a dry environment to prevent clumping. If using a reclaim system, screen out fines below 120 mesh to maintain consistent performance across cycles.
