Responding to changing needs in the electrical and electronics industry, DuPont Engineering Polymers has developed new grades of DuPont Zytel HTN high performance polyamide and DuPont Zenite LCP liquid crystal polymer. They include a new halogen-free, flame-retardant grade of Zytel HTN, which is compatible with high-temperature solder assembly and emerging electronic recycling systems. Meanwhile, new grades of Zenite LCP have been made available offering improved flow properties, higher temperature resistance or enhanced plating productivity. Halogen-free DuPont Zytel HTN
New Zytel HTNFR52G30NH is a 30 percent glass-reinforced PPA with a V-0 UL94 flammability classification and halogen-free formula. The absence of halogen in the new resin fits well with emerging recycling programs for discarded electronic products. Zytel HTNFR52G30NH also delivers the right property set for electronic connectors, relays, LED (lightemitting diode) components and various other electrical and electronic parts. It can withstand high-temperature circuit assembly methods, including those using lead-free solder, and it has good strength, stiffness and toughness over a wide temperature and humidity range. Zytel HTNFR52G30NH also has high tracking resistance needed for high-voltage parts. Its CTI (comparative tracking index) is greater than 600 V, the highest IEC 60112 classification. This may allow closer spacing of current-carrying parts than lower-CTI materials. Processing productivity is a further strength of the new resin. It has excellent thermal stability and can be moulded in tooling using water for temperature control.
