Ehthanol was once viewed as a way to help solve the climate change problem. Then we heard about the huge amounts of enegy used to make ethanol, anad then the effects of crop prices. It turns out there’s another issue–the impact on plastic used under the hood.
A new fuel tank pressure sensor from Robert Bosch GmbH uses BASF’s Ultramid T KR 4355 G7, a partially aromatic polyamide (PA 6/6T) that fulfills a new and crucial requirement for materials used in electronic housings. Any material that comes into contact with modern fuels has to be able to resist not only gasoline but also water and alcohols such as methanol and ethanol. These substances are found in the tank, especially due to the emergence of flex fuels that contain alcohol. The new polyamide (also called nylon) can withstand the presence of zinc chloride. At the underbody area the sensor may come into contact with this zinc salt that can be formed by splash water.
At the JEC Europe 2015 composites show in Paris last month, makers of composite materials, software, and process equipment showed off their latest innovations. This year's show saw some announcements related to automotive applications, but many of the improvements came in the world of aerospace.
The DuPont-sponsored Plastics Industry Trends survey shows engineers want improved performance in a broad range of plastics and better recycling technology. These concerns top even processing enhancements that improve productivity.
Plastics leader SABIC recently announced a global initiative to help its customers take advantage of additive manufacturing (AM) and also advance 3D printing (3DP) technologies in several application areas. The company's plans go way beyond materials, and also include design, processing, and part performance.
A theme that was reflected in several ways at NPE 2015 was the use of 3D printing to assist in, or improve on, injection molding, as well as improvements in 3D printing materials and processes that are making better functional prototypes and end-use parts.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
