The T20 sockets, moulded from DuPont™ Zytel® HTN PPA (polyphthalamide) withstand higher temperatures than the S8 sockets used in most North American cars. Empire moulds the new 2.8 In-Line connector series from hydrolysis-resistant DuPont™ Crastin® PBT thermoplastic polyester resin.

T20 sockets predominate in European and Japanese vehicles but are now gaining broader use in North America. Empire’s T20s deliver the same power output as S8 sockets but are more compact. Their reduced footprint and smaller socket hole opening give automotive lighting designers more styling freedom and a larger potential reflecting area, but they result in higher operating temperatures.
“Zytel® HTN PPA allows us to meet our customers’ stringent temperature requirements for T20s while giving us several pluses over alternatives such as modified polyphenylene oxide,” said Robert Gray, Empire’s director of program management. “Key advantages for the PPA material we selected are very low outgassing, good moulding productivity and the excellent technical support provided by DuPont.” The material’s low outgassing greatly reduces film formation on lighting lenses, which reduces light output over time.
The sockets in Zytel® HTN PPA consist of two moulded parts assembled by the cost-effective ultrasonic welding process. Each part can be colour-coded as an identification aid in wire harness assembly and installation.
DuPont™ Zytel® HTN high-performance polyamide resins are engineered for extremes for demanding environments. The portfolio includes both Zytel® HTN PPA grades for heat, chemical and moisture resistance and Zytel® HTN structural grades. Empire uses a toughened, glass-reinforced grade of Zytel® HTN PPA that can use water for mould temperature control. “We like water control because it avoids the added cost of oil-type control equipment and makes it easier to maintain a safe, clean moulding operation,” Gray said.
For its new 2.8 In-Line connector series, Empire selected a glass-reinforced grade of Crastin® with outstanding hydrolysis resistance. Gray explained the choice: “The Crastin® resin gives us a combination of hydrolysis resistance, dimensional stability, an excellent balance of strength and impact resistance, and high flow for easy moulding.” The connectors comply with demanding USCAR requirements for retention of terminal pullout resistance and other key functional characteristics after rigorous thermal cycling tests involving hot, cold, humid and dry conditions.
“DuPont gave us great service in our development of both sockets and connectors,” Gray said. DuPont specialists accelerated Empire’s development of marketable parts with expert input on material selection, design, tooling and ultrasonic welding. The DuPont Application Development Center in Troy, Michigan, conducted initial moulding trials.

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
