Motors for household appliances meet rigorous performance and safety requirements

Zytel® nylon 66 flame retardant resin was chosen by a manufacturer of motors for small household appliances, such as washing machines and dishwashers, due to its motor insulation abilities for high temperature performance. The Zytel® grade chosen is glass-reinforced and was also selected for its good processability, fast cycling time, and ability to meet safety requirements.


Safety requirements met by Zytel® include:

  • GWT > 750°C (glow wire temperature meets of exceeds 750°C at 0.75 mm)
  • CTI > 250 V (IEC proof tracking index meets or exceeds 250 V)
  • Electrical insulation Class F (155°C)
  • RTI > 130° C
