Crumb rubber is a term usually applied to recycled rubber from automotive and truck scrap tires. During the recycling process steel and fluff is removed leaving tire rubber with a granular consistency. Continued processing with a granular and/or cracker mill, possibly with the aid of cryogenics, reduces the size of the particles further. The particles are sized and classified based on various criteria including color (black only or black and white). The granulate is sized by passing through a screen, the size based on a dimension (1/4") or mesh (holes per inch : 10, 20, etc.).

• 24 mesh
• 30 mesh
• 35-40 mesh
• 50-60 mesh
• 80 mesh

No.3 Tire Granule shall consist of granulated tire crumb, Black Only Guaranteed MetalFree, sized. Magnetically separated materials are not acceptable. Fluff from tire cord removed.
40 and 60 mesh refers to material that has been sized by passing through a screen with 40 and 60 holes per inch.

Mesh 40 and 60

Mesh refers to material that has been sized by passing through a screen with a given number of holes per inch (25.4 mm) distant. For example, 40 mesh crumb rubber has passed through a screen with 40 holes per inch resulting in rubber granulate that is slightly less than 1/40th of an inch. The exact size will depend on the size of wire used in the screen.
