Tedlar® Release and Protective Films for Wind Turbine Blades

Tedlar® Release and Protective Films for Wind Turbine Blades

Wind turbine blades protected with Tedlar® PVF films resist weathering, moisture and UV rays, have low drag and exceptional performance.

DuPont™ Tedlar® PVF films are used in the production of wind turbine blades as both a release film and a protective surface. As a protective surface Tedlar® has the ability to resist weathering, moisture and UV rays, while also offering low drag to effectively keep surfaces clean. Tedlar® has demonstrated exceptional performance in marine/salt water environments.
