¡¡¡¡Resonator Made of DuPont Zytel PLUS 95G35 aims to reduce the typical high-frequency air intake sound to a lower level, so improving driving experience. ¡¡¡¡Zytel PLUS is a high-performance polyamide, produced with DuPont¡¯s proprietary SHIELD technology which provides superior long-term resistance to high temperatures and aggressive fluids typical of under-the-hood applications. Due to its function, the resonator has a relatively large volume, but - thanks to an optimised design in terms of wall thicknesses and the use of this high stiffness and high strength grade of Zytel PLUS - it weighs just 1.5 kg. ¡¡¡¡DuPont¡¯s proprietary SHIELD technology combines several innovations including a new polymer backbone, polymer modifications and a special set of additives which can double or triple the service life of standard nylon on exposure to hot environments and aggressive chemicals . DuPont Zytel PLUS 95G35, the core product of the Zytel PLUS family, shows no significant drop in its ability to withstand load - even over 4,000 hours of testing at 180 ¡ãC - whereas a traditional PA 66 GF35¡¯s ability to withstand load is cut to less than half. This resilience makes it attractive for use in cylinder head covers, resonators, exhaust mufflers and oil pans.
