Plastic Abrasive (Plastic Media) Blasting Consumable
Low-density, dust-free, no-residue plastic abrasive used in precision surface treatments; offered in 6 types — Urea, Melamine, Acrylic, Polyamide, Polycarbonate and Phenolic.
- 6 different plastic types, 11 different size options — chosen to suit precision blasting needs
- Does not create dust, does not leave residue/contamination on the surface, does not cause dimensional change
- Internal structure hardens with impact — higher surface effect with repeated use
- Can be used in all pressure, vacuum-suction, turbine and wet blasting systems
Product Description
Low-density plastic abrasive blasting consumables are used in very delicate surface treatments; they are suitable for air and turbine blasting systems. They allow cleaning without damaging the surface of the material being blasted, do not create dust, and do not cause residue/contamination on the surface.
Commonly used for blasting thermoset, duroplastic and pressure die-cast aluminum materials, plastic abrasives offer dust-free operation. As with stainless steel beads, plastic abrasives also undergo internal structure hardening depending on the amount of impact.
6 Plastic Abrasive Types:
| Type | Hardness (Mohs) | Description |
|---|---|---|
| Urea Plastic Abrasive | 3.5 | The most common and versatile type. Used for removing coating, paint, dirt and flash. |
| Melamine Plastic Abrasive | 4 | The most aggressive and brittle type. Used on less delicate surfaces where speed is required. |
| Acrylic Plastic Abrasive | 3.2-3.5 | The least aggressive and softest. Aerospace applications, metal/electronics deflashing. |
| Polyamide (Nylon) Plastic Abrasive | — | Automotive and thermoset industry. Not suitable for cold deflashing. |
| Polycarbonate Plastic Abrasive | — | Automotive, electronics, industrial applications; rubber and thermoset industry. |
| Phenolic (Phenol Resin) Plastic Abrasive | — | A type of granule made from Urea, Phenol, Polyester or Melamine resin; used for blasting thermoset and duroplastic materials. |
