Two DuPont™ Zytel® HTN PPA products help tyre pressure monitoring system stand up to pressures of the road

20.02.2008
SmarTire Systems Inc. tapped DuPont Automotive and high performance characteristics of DuPont™ Zytel® HTN PPA and Zytel® HTN PPA SuperStructural resins for a lightweight and durable casing for SmarTire’s new externally-mounted Tire Pressure Monitoring System (TPMS) used as part of the SmartWave® system for commercial trucks.

The new SmartWave® external, valve stem-mounted TPMS uses Zytel® HTN PPA SuperStructural resin for the housing and Zytel® HTN PPA for the cap. “Protecting the SmartWave electronic sensors inside the housing is paramount and the best way to create a non-permeable seal that withstands the rigors of external road conditions is through laser welding,” said Dan Jones, assembly manager for DuPont Automotive. “Our laser-welding leadership and competency in Asia Pacific really helped ensure we create a permanent joint in this inaugural project despite the dissimilarities of the two materials.”

The new SmartWave® external, valve stem-mounted TPMS uses two Zytel® HTN PPA resins, and marks DuPont’s first use of laser welding to assemble dissimilar products in North America. The non-permeable seal created by laser-welding provides all-weather protection for the sensor while the Zytel® HTN PPA surround is heat resistant and durable.

Zytel® HTN PPA SuperStructural resins offer the rigidity, durability, plus impact and heat resistance required to meet heavy tire spin loads, intense pressure levels that can reach 200 PSI and heat in the brake assembly area that can reach 200 °C. The average commercial vehicle travels one million miles in five years.

The new SmartWave® external TPMS is due to be released to the market in 2008 and offers installation benefits for retrofit applications.

“Our customers have asked for an external TPMS that can effectively provide performance cost data, is convenient to retrofit and is durable enough to withstand the harsh conditions that commercial trucks face,” said Shawn Lammers, VP Engineering, SmarTire Systems. “The reply? SmarTire’s external TPMS.”

Two of the top three commercial truck market’s financial concerns surround fuel economy and tire costs, both of which a tire pressure monitoring system can help manage. By integrating with the vehicles’ existing J1939 communications network, the system can relay vital information to the driver through a variety of display mechanisms and even communicate information remotely to a central routing depot through telematics systems.

Due to the size of the unit, the available surface area and the cost of the labeling process, as well as exposure to outside elements, the units are all laser-etched with bar code and text information. This will ensure that the units will continue to carry all of their necessary information for tracking and information purposes.

SmarTire develops and markets proprietary advanced wireless sensing and control systems worldwide under the SmartWave® trademark. The company has developed numerous patent-protected wireless technologies and advanced tire monitoring solutions since it was founded in 1987. The company’s proprietary SmartWave® platform provides a foundation for the addition of multiple wireless sensing and control applications. The initial product release on the SmartWave® platform is SmartWave® TPMS, which leverages on the company’s background and knowledge in tire monitoring solutions.

Im Focus: The working of a molecular string phone

Researchers from the Department of Atomically Resolved Dynamics of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg, the University of Potsdam (both in Germany) and the University of Toronto (Canada) have pieced together a detailed time-lapse movie revealing all the major steps during the catalytic cycle of an enzyme. Surprisingly, the communication between the protein units is accomplished via a water-network akin to a string telephone. This communication is aligned with a ‘breathing’ motion, that is the expansion and contraction of the protein.

This time-lapse sequence of structures reveals dynamic motions as a fundamental element in the molecular foundations of biology.

Im Focus: Physicists from Stuttgart prove the existence of a supersolid state of matte

A supersolid is a state of matter that can be described in simplified terms as being solid and liquid at the same time. In recent years, extensive efforts have been devoted to the detection of this exotic quantum matter. A research team led by Tilman Pfau and Tim Langen at the 5th Institute of Physics of the University of Stuttgart has succeeded in proving experimentally that the long-sought supersolid state of matter exists. The researchers report their results in Nature magazine.

In our everyday lives, we are familiar with matter existing in three different states: solid, liquid, or gas. However, if matter is cooled down to extremely...
