Circular content in tyre and retreading compounds
A retreader evaluated recovered carbon black in non-tread compounds to bring circular material back into tyres.
The customer wanted to show customers a circular story, using material recovered from end-of-life tyres in its own retreading compounds, without affecting safety-critical performance.
- 01Limited trials to non-critical compounds
- 02Agreed test plan and safety margins with the customer
- 03Supplied trial lots with batch documentation
- 04Supported compound and line evaluation
| Parameter | Result |
|---|---|
| Processing and cure behaviour | Met agreed criteria |
| Tensile and tear properties | Met agreed criteria |
| Ageing resistance | Met agreed criteria |
| Consistency between batches | Met agreed criteria |
Recovered carbon black was accepted for selected non-critical compounds, closing the loop from end-of-life tyre back into tyre products.
