An ECO-friendly option
Driven by sustainable innovation we developed Keltan® ECO, the world’s first commercial EPDM produced in Brazil from bio-based feedstock. The ethylene used in this process is derived from ethanol produced from sugarcane.
The Keltan®ECO grades have exactly the same specifications as their conventional counterparts, they are “drop-in” equivalents with one important difference: up to 70% of the content is bio-based! Thus, they offer an environmentally friendly alternative for any type of EPDM application.
Today these new bio-based EPDM grades are commercially applied in applications, such as low-weight, micro porous automotive solid seals and recyclable applications.
