Advancing Electrification With Ryton®

Ryton® Supreme: The Pinnacle of PPS Excellence

Remaining at the forefront of specialty polymer innovation for electrification, we proudly introduce the latest addition to the Ryton® family of high-performing polymers: Ryton® Supreme HV and HF.

Our latest Ryton® Supreme materials answer the automotive OEMs and Tier 1 suppliers' call for improved safety, reliability, and sustainability without compromising quality or system cost efficiency. From a higher CTI retention than the standard PPS to enhanced thermal resistance, Ryton® Supreme materials demonstrate best-in-class performance. 

Ryton® Supreme HV

Ryton® Supreme HV is a PPV material with high voltage capabilities. It boasts an impressive comparative tracking index (CTI), making it a top performer in electrical performance while keeping flame retardancy properties. It also demonstrates exceptional heat resistance in high-temperature environments. Additionally, Ryton® Supreme HV is a game-changer in creating safer and more expendable components for power electronics because of its flammability ratings. 

Key Properties: 

  • Comparative tracking index (CTI) of 600 V
  • Electric Thermal index (RTI) >175°C for exceptional heat resistance
  • 80% of dielectric strength retention after 5000h at temperatures >175°
  • UL94 V0 flammability ratings
  • More than 50% retention of CTI (>300 V) after aging at 175°C for 2400 h.
  • Impressive processability

Key Applications:

  • Power modules
  • Inverters


Ryton® Supreme HF

Ryton® Supreme HF provides superior mechanical strength and impressive flowability for components needing thin-wall thickness. Its improved thermal conductance, thanks to its thinner wall capabilities, also responds to the market's high reliability on concentrated winding E-motors. By enabling miniaturization and package optimization, this material can significantly influence and facilitate the automotive industry's stride toward lightweighting. Its increased toughness allows for thinner designs without compromising optimal performance at higher temperatures.

Key Properties: 

  • Flowability for components with a thin-wall thickness of 0.3 mm
  • Reducing coil temperatures

Key Applications: 

  • Bobbins/Winding Tooth
  • Insulators
