Keltan® Eco EPDM (ethylene-propylene-diene monomer) is a bio-based rubber derived from sugarcane.
The Keltan® eco line includes six (6) grades of eco EPDM ranging from 50 70% bio-content: 3050, 8550, 5470, 9950, 6950 and Keltan 0500R.
Most grades include 50% bio-based content, while the 5470 has 70%.
Arlanxeo claims that the bio-content of each material can be validated by the ASTM D6866, Carbon-14 test.
Eco EPDM offers equivalent performance to conventional, petroleum-based EPDM. It can be used as a high performance, heat and weather resistant elastomer (up to 150° C) for several demanding automotive applications, such as seals for coolants, brake fluids, hydraulic fluids and steam.
The bio-based component (bio-ethylene) is derived from Braskem’s sugarcane processing facility in Triunfo, Brazil. In addition to the sustainability advantages of its renewable origins, eco EPDM has the potential to reduce CO2 emissions in rubber articles by over 50%.
As a drop-in replacement for conventional EPDM, this bio-based material may also be used in tire and tube applications, aerospace seals, lubricant and oil additives, geothermal applications and much more.
Example Applications:
- High heat and weather resistant elastomer for:
- Automotive and Transportation
- Building & Construction
