New halogen-free DuPont Zytel HTN meets electronic recycling needs

Du Pont Engineering Polymers : 26 July, 2006  (New Product)
With a V-0 UL94 flammability classification, a halogen-free formula and other desirable properties, a new DuPont Zytel HTN high-performance polyamide resin meets emerging requirements of electronic component manufacturers around the world. The new material, a 30 percent glass-reinforced PPA designated as Zytel HTNFR52G30NH.
With a V-0 UL94 flammability classification, a halogen-free formula and other desirable properties, a new DuPont Zytel HTN high-performance polyamide resin meets emerging requirements of electronic component manufacturers around the world. The new material, a 30 percent glass-reinforced PPA designated as Zytel HTNFR52G30NH.

The absence of halogen in the new resin fits well with nascent recycling programs for discarded electronic products. Zytel HTNFR52G30NH also delivers the right property set for electronic connectors, relays, light-emitting 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 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 another strength for the new resin. It has excellent thermal stability and can be molded in tooling using water for temperature control.
