DuPont™ Rynite®

UV-resistant PET molding and extrusion resins for photovoltaic module frames and components

For rigid, outdoor weatherable plastic parts that help speed photovoltaic power module manufacturing and installation The sun is setting on old-fashioned ways of making solar modules. To reach grid parity with photovoltaic power generation means more than just refining the power efficiency of the modules’ inner workings and electro-active layers. It also means faster manufacturing of building-ready PV generating systems. It means systems delivered in more convenient forms through wider market channels, to more people, able to more quickly install a reliable alternative or supplement to their current energy sources. The world of solar module design is entering a race for efficiency that goes beyond the science of semiconductors. Design-for-manufacturing becomes the key to affordable, mass-produced modules incorporating new, lightweight features that can help speed installations, as well. Shifting from metal to Rynite® resins for PV module frames, junction boxes and other components can help reduce system manufacturing costs and improve the speed and ease of installations..

Design for mass production and assembly of rigid framing, junction box and interconnect components. Simplify module handling and transport through functional parts integration, such as built-in handles and protective elements. Reduce total delivered system cost through faster, more reliable, simpler field installation.

Solar power, meet DuPont plastics power DuPont Engineering Plastics has long been a valued development partner and high-performance raw materials supplier to electrical and electronics manufacturers worldwide. DuPont’s molding and extrusion resins include a broad selection of UL-recognized materials that have been time-proven and well integrated into global parts and shapes value chains. DuPont supplies nylon, acetal, polyester, liquid crystal, ionomer, polyimide and other resins including a number of high-temperature specialties suited to electrical and electronics structures and insulating parts.

DuPont™ Rynite® enables UV-resistant plastic components A proven leader in precision-molded connectors, housings, small motors, coil winding forms, oven handles and similar applications, glass-reinforced DuPont™ Rynite® PET resins offer an ideal combination of toughness, high-temperature performance, rigidity, creep resistance and volume-oriented manufacturing efficiency. Molded into discrete shapes, or extruded into channels, profiles or framing components, Rynite® can significantly reduce manufacturing and assembly costs for a new generation of photovoltaic power generation.


Familiar to molders everywhere Rynite® PET resins are backed by decades of electrical and electronics manufacturing experience and continued expert development support from DuPont. That means you can quickly find adaptable design and tooling concepts, well understood by parts suppliers ready to serve the needs of photovoltaic module manufacturing. The versatile polymer is available in a wide selection of grades, fully compounded, ready to process. Technical development and test support capability from DuPont ranges from tooling design guidance to assisting in molding and extrusion trials. DuPont labs worldwide offer a wide array of testing capability, from weathering and material interaction studies, to dielectric and mechanical testing.
