DuPont™ Rynite® PET: Ideal for Electrical Encapsulation
DuPont™ Rynite® PET thermoplastic polyester resin offers an excellent combination of thermal stability, electrical properties, dimensional stability and stiffness, making it ideal for coil forms and electrical encapsulation.
Specifically, DuPont™ Rynite® PET meets the requirements of UL94-V-0 at 0.4 mm and IEC-60335 GWT of >775°C. With a relative thermal index (RTI) of 155°C and insulation ratings of class B (130°C) to class N (200°C), DuPont™ Rynite® PET offers excellent thermal endurance.
With demonstrated performance in through-hole mounted lead-free soldering assemblies, DuPont™ Rynite® PET maintains a very high dielectric strength across a wide temperature range (23˚C to 150˚C).
