Melamine Plastic Media
(Type III)

When surface definition and dimensional accuracy are non-negotiable, abrasive selection becomes critical. Melamine Plastic Media (Type III) offers ultra-clean performance tailored for fine-detail cleaning and delicate mold maintenance.

for Precision Surface Finishing

Melamine Plastic Media (Type III), a.k.a Melamine (Type III) Plastic Abrasive Grit, is a high-performance thermoset abrasive engineered for demanding applications requiring both aggressive stripping and substrate protection. As the hardest plastic media (MOH hardness 4.0), it offers the most effective stripping rate among plastic abrasives, while still being non-destructive to sensitive materials.

Melamine media is durable, reusable, and generates minimal dust. It does not produce heat during blasting, making it suitable for temperature-sensitive components. It is also an excellent alternative to harsher abrasives like glass beads, providing superior surface integrity.

Compliant with MIL-P-85891 standards, this media is used across aerospace, automotive, electronics, and defense industries for precision surface treatment. Its consistent performance and substrate-safe characteristics make it a reliable choice for professionals worldwide.
