Plastic Abrasive




One of the biggest challenges manufacturers face is selecting the right abrasive blasting media for their metal finishing processes. Plastic blast media makes an excellent choice for many industrial applications.

Plastic abrasive is characterized as a less aggressive media than most other abrasives making it ideally suited for blasting on softer substrates and commonly used for the deflashing of plastic components, mold cleaning, the removal and cleaning of anti-corrosion coatings, hydrocarbon deposits, waxes, adhesives, and sealants. High durability, Free of Silica, no residual deposits results in a highly effective cost-effective media choice.

Plastic Blast Media Characteristics

Angular, Lightweight Material

Plastic media is an angular, lightweight material that can be produced in varying levels of hardness to meet a wide range of metal finishing requirements. This makes it ideally suited for removing organic coatings without damaging the underlying component surface.

A Preferred Choice for Stripping

Plastic is a preferred choice for stripping and cleaning applications involving aluminum composites and other delicate materials.

High Velocity Applications

The light weight of the plastic particles enables the plastic media blasting equipment to apply the material at a high velocity without significant mass, allowing for an extremely fast stripping process.

What Are the Types of Plastic Abrasive Media?

There are two basic types of plastic media: urea-methanal and resin-bonded polyester. Urea-methanal is the gentler of the two types and is regarded as synthetic media that can produce a bright, reflective finish on materials that will not undergo an additional electroplating step as part of the finishing process.

Resin-bonded polyester produces a smoother finish and results in very good anodizing, which increases the thickness of the oxide layer on the surface of the substrate.

Common Plastic Media Blasting Applications (Stripping and Cleaning) and Industries

Plastic abrasive media is now the preferred choice for paint stripping applications in the automotive industry. Most plastic media are harder than paint but softer than the thin gauge sheet metals used to manufacture automotive parts such as hoods, fenders and frames. Thus, the plastic media blasting process will cut, shear and lift the paint without damaging the part surface.

And since plastic media blasting is a dry process, there is no residual flash rust and no concerns about warping or pitting.
