One is Rynite FR533NH, the company's first halogen-free PET compound for IT equipment such as chargers, transformers, relays, switches, and motors in unattended household appliances. Containing 33% glass, it reportedly offers improved flow and lower density than halogenated PET compounds, which makes it a more economical solution. It also boasts "the best long- term heat-exposure performance in the market," DuPont says. The second new product is Zytel LT70G35EF, a laser-transparent black nylon 66 with 35% glass, suitable for automotive electronics. It eliminates the need to laser weld a clear part to a black part—now both parts to be joined can be colored black, as automotive customers have wanted. Also, its electrical properties are said to be stable after exposure to 85 C and 90% RH. 800-441-0575 • plastics.dupont.com MATERIALS A new family of marine-grade PC glazing sheets for flexible boat enclosures are now available from Covestro, Pittsburgh.
