The size of rubber powder is typically measured in mesh, which indicates the number of openings per square inch of the sieve screen. A higher mesh count signifies finer powder particles. Rubber powders of different particle sizes have significantly different applications.The following is an overview of common rubber powder mesh sizes, their corresponding physical dimensions, and typical application scenarios:
| mesh | aperture size(mm) | rubber particle size(mm) |
| 5 | 4.0 | 4.0 |
| 8 | 2.5 | 2.362 |
| 10 | 2.0 | 1.7 |
| 16 | 1.18 | 1.0 |
| 20 | 1.00 | 0.833 |
| 24 | 0.75 | 0.701 |
| 26 | 0.71 | 0.635 |
| 30 | 0.6 | 0.542 |
| 40 | 0.45 | 0.38 |
| 60 | 0.28 | 0.25 |
| 80 | 0.22 | 0.18 |
I. Coarse rubber powder (5–30 mesh)
Characteristics: Large particle size, good elasticity, and high air/water permeability. Key applications: Primarily used for sports track surfacing, artificial turf infill, rubber floor tiles, sound insulation pads, and automotive underbody anti-collision coatings.
II. Medium-fine rubber powder (40–60 mesh)
Characteristics: Balances strength and elasticity; easy to blend with virgin rubber. Key applications: Widely used in tire retreading, conveyor belt manufacturing, rubber hoses, rubber sheets, waterproofing membranes, and shoe sole materials.
III. Fine rubber powder (80–100 mesh)
Characteristics: High specific surface area and high reactivity; excellent compatibility with polymer materials. Key applications: Commonly used in the manufacture of high-performance tires, waterproof coatings, sealing rings, and shock-absorbing products, as well as an additive for asphalt modification (enhancing highway resistance to aging and cracking).
