Rubber Crumbs

Recycled Crumb Rubber

NHA Rubbers manufactures Recycled Crumb Rubber by mechanically processing end-of-life tyres into recycled rubber particles with controlled particle-size classification for industrial and commercial applications. Through a controlled recycling process involving shredding, steel separation, fibre removal, granulation and particle-size screening, recovered tyre rubber is converted into a reusable secondary raw material suitable for sports surfaces, synthetic turf, playground flooring, rubber flooring, road construction and a wide range of rubber-product manufacturing applications.

Our Recycled Crumb Rubber is available in black with particle sizes ranging from 0.8 mm to 4 mm. Custom particle sizes can also be considered according to specific application and order requirements.

What Is Crumb Rubber?

Crumb Rubber is a recycled rubber material produced by mechanically processing end-of-life tyres into controlled particle-size rubber granules for industrial and commercial applications.

During the recycling process, tyres are cut and shredded before steel and textile fibre are separated from the rubber. The recovered rubber is then progressively reduced in size, screened and classified into defined particle-size ranges for different application requirements.

The resulting material retains the inherent resilience and flexibility of rubber, allowing it to be reused as a secondary raw material across a wide range of industries.

Depending on particle size and application requirements, Recycled Crumb Rubber can be used in synthetic turf systems, sports and playground surfacing, rubber flooring, rubber-product manufacturing, road construction and other industrial applications.

How Is Recycled Crumb Rubber Made?

Recycled Crumb Rubber is manufactured by recovering rubber from end-of-life tyres and mechanically processing it into defined particle-size ranges for different industrial and commercial applications.

A typical recycling process includes:

1. Collection and sorting of end-of-life tyres.
2. Initial cutting and shredding into smaller tyre pieces.
3. Progressive size reduction of the shredded material.
4. Separation of steel and metallic components using magnetic separation.
5. Removal of textile fibre and other unwanted materials.
6. Granulation of the recovered rubber.
7. Screening and classification into the required particle-size range.
8. Inspection of particle-size consistency and material cleanliness.
9. Packaging according to customer and transportation requirements.

The exact processing stages may vary depending on the required particle size and intended application.

The objective of the recycling process is to recover usable rubber while reducing the presence of residual steel, textile fibre and other unwanted materials before the finished material is supplied for further use.

Available Crumb Rubber Size

• Coarse Crumbs – Suitable for playgrounds and landscaping
• Medium Crumbs – Ideal for sports surfaces and flooring
• Fine Crumbs – Used in turf infill and industrial blending

 

Custom particle sizes can also be considered according to specific requirements.

The correct Crumb Rubber size should always be selected according to the intended application and performance requirements.

Key Performance Characteristics of Crumb Rubber

High Rubber Content

With a listed rubber content of 98–99%, the material provides a high proportion of processed recycled rubber for suitable secondary applications.

 

Controlled Metal Content

The listed metal content is less than 0.01%, reflecting the separation of metallic components during tyre recycling and processing.

 

Low Free Fibre Content

Free fibre content is listed at less than 0.5%, helping reduce unwanted textile contamination in the processed Crumb Rubber.

 

High Compressibility

The compressible nature of rubber makes Crumb Rubber suitable for applications where resilience, cushioning and impact management are beneficial.

Actual performance depends on the design and construction of the complete surface or finished product.

 

Low Water Absorption

The material has listed water absorption of less than 1% by weight.

This characteristic can be relevant for selected flooring, sports and outdoor applications, although the suitability of the complete system should be evaluated separately.

 

Wide Temperature Range

NHA Rubbers' Crumb Rubber has a listed temperature resistance range of -30°C to 70°C.

Application suitability should be evaluated according to actual environmental exposure and the characteristics of the complete finished system.

 

Flexible and Resilient

With listed hardness of 60–75 Shore A and elongation at break of 180–250%, the material retains characteristics associated with processed rubber.

These properties can contribute to its suitability for selected resilient surface and rubber-product applications.

Crumb Rubber and the Circular Use of End-of-Life Tyres

End-of-life tyres contain valuable rubber material that can be recovered and processed for new applications.

The recycling journey can be represented as:

End-of-Life Tyres → Collection & Sorting → Shredding → Steel & Fibre Separation → Granulation → Screening & Sizing → Quality Control → Recycled Crumb Rubber → New Applications

Depending on its specification, the recovered Crumb Rubber can enter another lifecycle through sports infrastructure, synthetic turf systems, playground surfaces, rubber flooring, manufactured rubber products or specialised road applications.

This process helps extend the useful life of recovered rubber resources and supports a more circular approach to material utilisation.
