DuPont™ Rynite® PET: Ideal for Electrical Encapsulation

Resin for Electrical Encapsulation | DuPont™ Rynite® PET

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, Rynite® meets the requirements of UL94-V-0 at 0.4 mm and IEC-60335 GWT of >750°C. With a relative thermal index (RTI) of 155°C and insulation ratings of class B (130°C) to class N (200°C), Rynite® offers excellent thermal endurance.

With demonstrated performance in through-hole mounted lead-free soldering assemblies, Rynite® maintains a very high dielectric strength across a wide temperature range (23˚C to 150˚C).
