EPDM Rubber Grades Offer Up to 55% Lower Carbon Footprint
As manufacturers face growing pressure to reduce the carbon footprint of their products without sacrificing material performance, sourcing drop-in alternatives to traditional fossil-based elastomers has remained a persistent challenge. Trelleborg's E7T11 and E8T12 are two EPDM rubber compounds formulated from bio-circular raw materials, offering up to 55% lower product carbon footprint (PCF) compared to conventional fossil-sourced EPDM, with equivalent application performance.
Both grades are derived from polymers based on non-fossil feedstock, including used cooking oil, straw, forestry residue, and tall oil. The compounds combine these bio-circular EPDM polymers with recycled carbon black sourced from used tires and other materials.
In compound form, E7T11 (70 Shore A) achieves a 51% PCF reduction and E8T12 (80 Shore A) achieves a 61% PCF reduction compared to traditional materials. For molded articles, PCF reductions reach up to 33% for E7T11 and up to 55% for E8T12.
The bio-circular EPDM polymer base—supplied by Arlanxeo under its Keltan Eco-BC label—is ISCC PLUS certified using a mass balance approach, which tracks bio-circular feedstock use through the production chain and ensures that the volume sold as bio-circular is consistent with the source feedstock inputs.
PCF calculations were developed in partnership with Sphera Solutions using recognized methodology. Certification of that methodology by DEKRA, an internationally recognized certifying authority, is pending.
Both grades are suitable for O-rings, gaskets, and custom-engineered products.
