Polymer Passes the Sniff Test—and Then Some
Remember that “new car” smell?
Well, remembering may be all there is to it because according to polymer provider PolyOne, there is an increasing number of consumers who associate that smell with things like volatile organic compounds (VOCs) and so aren’t particularly keen on climbing into their brand-new vehicle and think that they’re being exposed to something that’s not good.
So to address this, in part, PolyOne has developed a low-odor, talc-filled polypropylene that’s is engineered for underhood HVAC applications such that it can help OEMs meet vehicle interior air quality (VIAQ) standards, as in achieving odor testing results of 3.0 per VDA 270 (which, in case you’re wondering: “The test is intended for the evaluation of the odour behaviour under the influence of temperature and climate. The test will be performed on materials and parts of the automotive interior and on parts in contact with the supply air to the interior,” according to Verband der Automobilindustrie).
Named Maxxam LO, the material reduces odors while maintaining its performance and aesthetic characteristics.
Perhaps the only thing people will be smelling in cars is something like this:

Many countries who once were major players from a vehicle production/export perspective are finding it difficult to even find their niche today.
Ram Truck chief exterior designer Joe Dehner talks about how they’ve developed the all-new pickup. “We’ve been building trucks for over 100 years,” he says. “Best I could come up with is that this is our 15th-generation truck.”
Topology optimization cuts part development time and costs, material consumption, and product weight. And it works with additive, subtractive, and all other types of manufacturing processes, too.
