30-mesh crumb rubber is a medium-fine grade of rubber powder, meaning the particles are small enough to pass through a screen with 30 openings per inch. It's produced from scrap tires and used in various applications, including sports surfaces, playgrounds, and asphalt modification. The "30 mesh" designation refers to the particle size, with finer grades having higher mesh numbers
Particle Size:30-mesh crumb rubber has a particle size of around 600 microns (0.6 millimeters
Production: It's typically produced through ambient mechanical grinding, where scrap tires are shredded, metal and fibers are removed, and the remaining rubber is ground and screened to isolate the 30-mesh fraction.
Applications: Sports Surfaces: Used as infill in artificial turf for cushioning and safety.
Playgrounds: Provides a soft, shock-absorbing surface for children's play areas.
Asphalt Modification: Added to asphalt mixes to improve durability, temperature resistance, and fatigue cracking resistance.
Other Uses: Can be used as a filler in rubber products, such as mats, roofing materials,and molded goods.
Characteristics: 30-mesh crumb read more rubber is free of steel and fiber content, and its particles are typically black.
