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 such as coil forms and electrical encapsulation, 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.

DuPont offers the industry’s largest portfolio of pre-approved Underwriters Laboratories (UL) electrical insulation systems (EIS) and recognized to IEC standards products.
