Protect people and the planet
Acting on climate
The traction motors that power today’s latest generation electric locomotives must deliver long-term reliable operations with improved safety margins in a variety of demanding situations and environments conditions.
Insulation around the wire of an electric motor is subject to high electrical and thermal stresses while operating. Specifications require that the insulation protects effectively at temperatures above 200o C when in continuous use.
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.
DuPont provides solutions that enable vehicle electrification and expansion of the electronic vehicle (EV) market, including thermal management, battery assembly, and enhanced connectivity
