What Is Crumb Rubber?

Crumb rubber is recycled rubber made by reducing scrap tires or rubber material into small, consistent particles. During processing, steel and fabric are removed, and the remaining rubber is ground, screened, and sorted into different particle sizes for specific applications. The EPA notes that tire crumb rubber is produced by reducing scrap tires and removing 99% or more of the steel and fabric before classifying the material by size.

Because crumb rubber is made from recycled rubber, it supports landfill diversion and gives end-of-life tires a second use in practical, high-demand application.

What Are Rubber Buffings?

Rubber buffings are recycled rubber particles typically generated during the tire retreading process. When a tire is prepared for retreading, the worn tread surface is buffed away, creating rubber particles known as buffings. These buffings can be used as-is or further processed depending on the required size, cleanliness, and application.

Rubber buffings are often used in pour-in-place playground surfaces, rubber tiles, mats, slabs, equestrian footing, turf systems, and molded rubber products. Suppliers commonly describe raw buffings as a practical feedstock for rubber parts manufacturing, pour-in-place applications, rubber tiles, slabs, loose fill materials, and arena footing.

In simple terms, crumb rubber is usually more processed and screened, while rubber buffings can be less refined and may vary more in particle size unless further classified.

Crumb Rubber vs Rubber Buffings: What Is the Difference?

Crumb rubber and rubber buffings both come from recycled rubber, but they differ in source and particle consistency.

Fibrous or irregular particles

 

Crumb rubber is often preferred when a consistent particle size is required. Rubber buffings are often chosen when flexibility, shock absorption, and cost-effective bulk material are priorities.

What Are Crumb Rubber and Rubber Buffings Used For?

Common applications include:

1. Playground surfacing

Crumb rubber helps create cushioned surfaces that reduced impact under play equipment.

  • Is the material screened or unscreened?
  • Is the rubber free of excess steel and fiber?
  • What packaging options are available?
  • Is the product suitable for playgrounds, turf, asphalt, landscaping, or manufacturing?
  • Can the supplier support bulk orders?
  • Can they provide technical guidance?
