DRIVER

"Rising demand for lightweight structural materials"

The switch toward lightweight structural designs in wind energy, aerospace, automotive, and marine is fueling PET foam adoption. For example, U.S. wind blade projects in 2023 demanded over 5,500 tonnes of foam cores. In Europe, over 10,000 MW of new wind capacity utilized PET foam cores in 2024.
