Super Fine Crumb Rubber Powder 80-Mesh
Crumb rubber powder is a recycled tire product made by grinding scrap tires into fine particles.
An 80-mesh size indicates a relatively fine powder, with particle diameters around 180 microns (0.18 millimeters).
Process:
- Ambient Mechanical Grinding:
This is the most common and economical method. Scrap tires are:
- Shredded into chips.
- Processed to remove steel belts with magnets and fibers through air separation.
- Ground in mills to achieve the desired particle size. For 80 mesh, this might involve multiple grinding passes to ensure consistent powder.
- Classified using screens or air classifiers to separate the crumb into different size fractions, isolating the 80 mesh particles.

Uses:
80 mesh crumb rubber powder finds application in various industries due to its balance between particle size and surface area. Here are some common uses:
Rubber Products: Used as a filler in rubber compounds to improve strength, impact resistance, and sometimes reduce production costs.
Construction Materials: Can be incorporated into asphalt mixtures to enhance elasticity, reduce cracking, and extend pavement life.
Plastic Modification: Blended with plastics to improve their properties like impact resistance and vibration damping. This can be useful in applications like automotive parts, flooring, and roofing materials.
Other Uses: Depending on the specific application, 80 mesh crumb rubber powder might also be used in:
- Artificial turf infill
- Noise reduction materials
- Blast media
- Specialty coatings
Additional Points:
- 80 mesh crumb rubber powder is an environmentally friendly product as it utilizes recycled tire rubber.
- The specific properties of the crumb rubber powder can be tailored depending on the processing methods and additives used.
- When handling crumb rubber powder, it is important to follow safety guidelines due to potential dust inhalation hazards.
