For more than 25 years, DuPont™ Elvax® ethylene-vinyl acetate (EVA) copolymers have been used in photovoltaic applications. Elvax® PV grades manufactured for the photovoltaic market are made using a proprietary process that helps ensure outstanding, consistent properties that meet the highest quality demands.

These include:

• Industry-proven optical capabilitiesFacilitates higher optics, which translates to higher efficiency and higher output, with lower costs per Wattpeak
• Low gel level Ensures uninterrupted lamination process and zero failures resulting from cell breaks in the module during lamination
• High polarity Provides excellent adhesion properties
• Ability to be pigmented Allows for further customization; available if needed for design effects
• Ability to be cross-linked Allows the film to be used as a thermoset material that will not degrade during operations in the sun, where temperatures can reach more than 90ºC in the module
• Superior performance Ensures consistent quality by running processes adapted to the PV grade and engaging UL as part of the ISO 9000 certification process

All Elvax® grades are supported by a technical team focused specifically on the requirements of the industry. In addition, customers wanting to advance module performance or manufacturing efficiency can contact us for additional data including proprietary or developmental grades of EVA encapsulant resins.
