Polyethylene Terephthalate for High-Performance Parts

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

With its lightweight, glass-reinforced composition, dimensional stability, durability, and high-gloss finish, DuPont™ Rynite® is preferred across a wide range of applications, particularly as a replacement of die-cast metals and thermosets.

This stiff, UV-resistant polymer offers a balance of thermal, mechanical, and chemical properties that make it ideal for electrical and electronic parts. Rynite® offers superior flow characteristics as well, which means it fills complex, thin-walled moulds with less injection pressure than is needed with other resins - a big advantage in the miniaturization of parts.

Rynite® polyethylene terephthalate (PET) helps make electrical devices, photovoltaic panels, switches, and other critical energy components stronger and reliable.
