Arkema is proud to present its unprecedented innovative project: the manufacture of wind turbine blades using thermoplastic polyester "Elium". This first-of-its-kind project in the U.S. was achieved by combining the expertise of major players in the composites industry. The collaboration was directed by the Institute for Advanced Composites Manufacturing (IACMI) and documented in film form.

Green energy is now becoming a real social issue. Arkema is here once again to demonstrate its commitment to sustainable development. For the first time in the United States, wind turbine blades are made from the thermoplastic resin "Elium".

The project was launched in Boulder, Colorado in January 2017 to test the feasibility of industrially producing wind turbine blades using thermoplastic composites. For the Arkema team, this project was also an opportunity to showcase the rich features of "Elium", including:

save energy

As a liquid epoxy resin, "Elium" resin and thermoset composites apply the same treatment and mold. However, because the mold does not need to be preheated, the energy consumption is much less. Moreover, the adhesive for the assembly of the blade parts can be used at room temperature, unlike thermosetting adhesives that require heating.

  Environmental friendly

Preliminary test results from Arkema have shown that blade components made from 'Elium' are more resistant than thermoset composites. And "Elium"'s thermoplasticity makes it easier to recycle. This is a major first and true innovation in high-performance materials.
