What is Crumb Rubber?

Crumb rubber is made of recycled tires that are cleaned, ground into smaller pieces and screened to obtain uniform sizes. Crumb ranges from particles so tiny they resemble dust to pieces about one-half inch long, or a little smaller than a dime. 

Crumb rubber offers the most versatility for recycled tires and arguably the highest value, as compression and injection molders, paving companies and synthetic turf installers use it to design a wide range of helpful products we encounter every day.

Versatile at the Core

Regardless of how it’s used, crumb rubber is the material of choice to lower costs, improve safety and advance lives. Beyond its sustainability, since it is made from recycled tires, rubber’s inherent properties are game changers in a vast number of industries, from consumer products to paving applications.

For compression molding, crumb rubber is elastic, durable and less expensive than virgin alternatives. Floor mats, weightlifting plates and playground products last longer when made with recycled rubber.

For sports infill, rubber is used in more than 80% of the synthetic turf fields nationwide. It drains more rapidly than any other infill product, dries quickly and is the most shock-absorbent infill material that can be used to protect kids and athletes alike from more serious injury.

For running tracks, crumb rubber is an excellent choice for a value-based system that provides a resilient, non-slip surface. It is also widely used as a base mat for a more specialized track surface.

For rubberized asphalt, including crumb rubber in roads makes them quieter, reduces stopping distances and can lower long-term maintenance costs.

With ground rubber, the possibilities are virtually endless. Are you looking for a material that is:

  • Extremely durable
  • Resistant to cracking
  • Good ductility
  • More cost-effective than virgin alternatives
  • Excellent shock-absorbing properties
  • 100% recycled material

Did You Know?

When tires are created, manufacturers include materials that protect the tires from deterioration caused by the ozone and the sun’s rays. These protective materials are retained in recycled rubber, one reason why crumb rubber is sought after by paving companies. For example, rubberized asphalt made from recycled tires remains darker in color for a longer time than asphalt alone. This increases road visibility and makes rubberized asphalt safer for drivers.
