ETERNAL rCB is a versatile reinforcing and colouring filler across non-tyre rubber. It supports high loading levels, disperses cleanly, and brings cost-in-use and sustainability advantages to compounds where virgin carbon black is traditionally used. The products below are where our customers apply it most, with the grades that typically fit best.

Rubber conveyor belt carrying recovered carbon black in an industrial plant

Conveyor & Transmission Belts

Tensile strength with high resistance to abrasion, cut and tear for heavy-duty belting compounds.

Engine mounts and anti-vibration rubber components on a steel frame

Engine Mounts, Bushings & Anti-vibration

Reduced hysteresis, improved flex fatigue and compression set, better metal bonding and shorter incorporation time.

Rubber seals, gaskets and O-rings on engine components

Seals, Gaskets & O-rings

Durable sealing compounds with good compression set for engines, pumps and piping.

Extruded rubber profiles and edge trims in various cross-sections

Extrusions & Profiles

Improved mechanical properties and flex fatigue with higher loading possibilities in extruded goods.

Diaphragms

Flexible membranes for pumps, valves and control devices regulating liquid and gas flow.

Insulating rubber grommets, boots and bushings on electrical equipment

Electrically Insulating Rubber

Enhanced resistivity while keeping mechanical and dynamic properties high — without diluting the compound with non-reinforcing fillers.

Black rubber shoe soles and footwear components

Footwear Soles & Components

Durability, comfort and slip resistance in soles for shoes and boots.

Rubber mats, rolls and interlocking floor tiles

Mats, Flooring & Rubber Sheets

Gym, industrial and playground matting, plus lining and padding sheets — well suited to high-loading, cost-driven compounds.

Black rubber-based sealant applied along a metal joint

Adhesives & Sealants

Rubber-based bonding and sealing systems for construction and automotive use.

Rubberised asphalt being laid and compacted by a road roller

Rubberised Asphalt & Construction

Performance and sustainability improvement in rubberised asphalt, sealants and linings.

Black electrical cable with rubber sheathing and moulded rubber parts

Cables & Industrial Rubber Goods

Electrical cable compounds and general industrial rubber articles where carbon black is standard.

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.
