Tyre & Tyre Components

Tyre manufacturing is the natural home of recovered carbon black — material recovered from end-of-life tyres returning into new ones. ETERNAL rCB can account for a substantial share of the carbon black in a new tyre when blended with virgin grades, bringing true circularity and EPR compliance along with cost benefits.

Innerliners

Blended with virgin CB in innerliner compounds, where moderate reinforcement demand makes rCB substitution most straightforward.

Carcass Compounds

Body ply and casing compounds accepting meaningful rCB substitution while retaining processing behaviour.

Sidewalls

Weathering-exposed compounds benefiting from consistent colour and reduced hysteresis contribution.

Treads (blended)

Partial substitution in tread formulations, tuned by trial to balance wear performance with sustainability targets.

Tyre Retreading

Retread and repair compounds — a cost-driven segment where rCB has an established fit.

Mud flaps, inner tubes, boots, bushes and moulded automotive rubber parts

Allied Automotive Rubber

Flaps, tubes and allied automotive rubber parts produced alongside tyre lines.

Grade Selection

Choosing the right grade

The right ETERNAL grade depends on your compound, your process and your specification — not on the application alone. Our technical team works with you directly to identify the grade that fits, and confirms it through trials on your own line.

Full specification ranges for every grade are published in the individual technical data sheets on our Products page, and third-party test data is on our Testing & Certification page. Anything shared with us about your formulation stays confidential.

Ready to test ETERNAL on your production line? Tell us your product and specification — we’ll work out the right grade with you and arrange samples.
