Acting on climate
Tedlar®-based backsheets on solar panel systems are the outermost “layer” for the panel and the first defense for solar cells. In order to protect a panel over its lifeapan of 25 to 30 years, the backsheet must have optimal balance of three critical properties: weatherability, mechanical strength and adhesion.
Tedlar® TPE Backsheet offers protection from UV, thermal moisture, mechanical and chemical stress. The film is more stable under heat and UV exposure than single-sided tie layers.

Based on the unique function of Tedlar® in installed solar panels, its beneficial effects as a material in helping reducing GHG emissions through renewable electricity production has been estimated:
Many wind farms are located in areas that experience severe cold weather, sometimes dropping well below 0°F for months at a time. Ice accumulation on a wind turbine blade erodes its aerodynamic performance and can lead to measurement and electrical failures as well as safety hazards.
DuPont Kapton® RS is an electrically conductive polyimide film developed for heating applications where a thin, lightweight, uniform heater is needed. Kapton® RS has the potential to prevent ice accumulation with reliability and safety performance that would otherwise result from electrical systems interacting with harsh conditions and temperature cycling. Kapton® RS is projected to recover up to 80% of icing losses.

The Indian government plans to have India’s railways routes fully electrified by 2023 and fully powered by renewable sources by 2030. DuPont Kapton® FCRC wire insulation coupled with DuPont Nomex® slot liner insulation is the standard for high efficiency traction motor insulation systems for demanding, high temperature rail applications,
Photovoltaic panels are expected to convert sunlight into energy for 30 years or more, but solar panels in the field often experience degradation and other failures that shorten their useful life, thereby reducing their ability to produce renewable energy. Tedlar-based backsheets have been demonstrated to significantly extend panel lifespan, with multiple examples of installations generating electricity well beyond 30 years.
In August 2021, Hurricane Ida significantly impacted our Pontchartrain, LA manufacturing facility. Preparations for site operations, employee safety and community recovery began days ahead and continued weeks after.
Hydrofluorocarbons (HFC) are used in blowing agents and manufacturing of other building insulation materials. Some HFCs have high global warming potential (GWP) where they end up in the atmosphere and contribute to climate change.
Creating a water-optimized future relies on innovation and action now, and in future generations.
The “Flow of Life” project promotes water science literacy and education across primary and secondary students in China.
Many rivers around the world are now classified as “high stress”. This means that more than 40% of the naturally available water in the basin is removed leading to the risk of water scarcity. Our Zhangjiagang site in China set a sustainability goal to reduce wastewater generation, and address other water usage opportunities.
