Today's power plants challenge the upper limits of many engineering thermoplastics, especially those that provide high temperature components and systems. PPA plastics offer great resistance to hydrolysis and moisture depending on cost-effective applications such as water inlet/outlet thermostat housings, pumps and impellers, tomorrow's challenge gap materials include alternative powerplant requirements for very high voltage electrical, electronic power Modules and battery systems require cooling coolant channels or cold start preheating. DuPont's Zytel® HTN “EF” resin (electrical type) and other new PPA resins meet the new and evolving needs of hybrid and plug-in electric vehicles for high voltage connections and separate thermal control systems. These emerging requirements are excellent traceability (Comparative Tracking Index Measurement), PPA plastic high volume resistivity to maintain humidity exposure, good ATF properties, and USCAR Class 4 performance (150 ° C). High performance polyamides meet demanding requirements for automotive thermal management components because they are in contact with hot, aggressive automotive fluids and hot air that is wet or dry, and high performance polyamide (HPPA) can make rugged, functional parts Maintain good strength and toughness for automotive thermal management and other demanding applications.
