Ultradur High Speed, a high-flow PBT that BASF introduced last year, has now become the company's first engineering plastic to receive an "eco-efficiency" label after a third-party review of the material's energy-saving potential. The material contains nano-scale additives that reduce its viscosity by roughly 50 percent — without sacrificing other properties. This easy flow has implications for molders trying to fill thin wall parts or cut cycle times. But it also has an environmental benefit in the form of energy savings. Extra flow can reduce the amount of energy needed to make a given part — by reducing molding machine temperatures, molding pressures and cycle times. The savings can be significant, according to an eco-efficiency review conducted by the Swiss Federal Institute of Technology. Energy usage from reducing molding machine heats and pressures can be 20 percent less than a comparable higher viscosity polymer. Cycle time reduction, with its obvious energy implications, can fall by 30 percent. For more information on Ultradur, go to http://rbi.ims.ca/4933-533.
A bold, gold, open-air coupe may not be the ticket to automotive nirvana for every consumer, but Lexus’ LF-C2 concept car certainly turned heads at the recent Los Angeles Auto Show. What’s more, it may provide a glimpse of the luxury automaker’s future.
The complexity of diesel engines means optimizing their performance requires a large amount of experimentation. Computational fluid dynamics (CFD) is a very useful and intuitive tool in this, and cold flow analysis using CFD is an ideal approach to study the flow characteristics without going into the details of chemical reactions occurring during the combustion.
