Super Fine Crumb Rubber Powder 120-Mesh
Crumb rubber powder is a finely ground product made from recycled tire tread.
A 120-mesh size signifies very fine particles, approximately 125 microns (0.125 millimeters) in diameter.
Process:
Ambient Mechanical Grinding:
This is the most common and cost-effective method for crumb rubber production.
Initial Size Reduction: Scrap tires are shredded into chips using large shredding machines.
Metal and Fiber Separation: The tire chips are fed into a granulator, which breaks them down further and separates out steel belts using magnets and fibers through air separation systems (shaking screens and wind sifters).
Grinding: The rubber crumb is then further ground in secondary mills or high-speed rotary mills to achieve the desired particle size. For a 120-mesh size, this grinding stage may involve multiple passes through the mills to ensure a consistent powder consistency.
Classification and Separation: The ground rubber powder is then passed through screens or air classifiers to separate it into different size fractions. Here, the 120 mesh sized particles are isolated.
Technical Specifications:
Mesh Size: 120-Mesh
Particle Size: Approximately 125 microns (0.125 millimeters)
Fineness: Extremely fine powder
Other Specifications (may vary depending on supplier):
Moisture content: Typically, less than 0.2%

Material: Recycled tire rubber (can be natural or synthetic)
Uses:
Due to its exceptionally fine particle size and high surface area, 120 mesh crumb rubber powder is ideal for applications requiring:
High Adhesion: Used as a filler in adhesives, sealants, and coatings for superior bonding strength.
Enhanced Material Properties: Blended with polymers or resins to create rubber composites with improved strength, flexibility, and other desired characteristics for applications like flooring, molded products, and specialty coatings.
Improved Asphalt Performance: Used in asphalt modification to enhance elasticity, fatigue resistance, and crack prevention in pavements.
Additional Points:
- 120 mesh crumb rubber powder is a sustainable product utilizing recycled materials.
- Specific properties can be tailored through processing methods and additives.
- Proper safety precautions are crucial when handling due to potential dust inhalation hazards.
