Rynite® PET Polyester Resin

Rynite® Polyethylene Terephthalate Combines Performance With Processability

Rynite® unites the best properties of reinforced polyethylene terephthalate (PET) with easier processability to produce high-performance parts.

DuPont™ Rynite® modified polyethylene terephthalate (PET) resin is well-matched to applications requiring durable electrical and electronic performance, and offers a high-gloss finish. Its lightweight, glass-reinforced composition provides dimensional stability, making it a prime candidate for the replacement of die-cast metals and thermosets. This stiff, UV-resistant polymer offers a balance of thermal, mechanical and chemical properties.

Outstanding flow characteristics allow Rynite® to fill complex, thin-walled molds with less injection pressure than is needed with other resins. This is a particularly important advantage in applications where there is a trend towards miniaturization of parts. Rynite® polyethylene terephthalate (PET) helps make electrical devices, photovoltaic panels, switches and other critical energy components stronger and reliable.



  • Sorona® EP thermoplastic polymer

    Sorona® contains 20-37% renewable non-food biomass and offers the strength, stiffness and molding characteristics of high-performance PBT.


  • Cost-effective photovoltaic junction box housings

    Junction boxes are installed by photovoltaic (PV) manufacturers directly on to the back of every PV panel and serve as the interface between the conductor ribbons on the panel and the DC input and output cables.
