Plastics & Masterbatch

In polymer systems ETERNAL rCB is a sustainable replacement offering easy milling and processing, reduced usage of thinning agents such as waxes and oils, straightforward dosing, and uniform distribution for consistent colouring. It fits masterbatch producers and converters looking to cut both cost and carbon footprint.

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.
