Lighter plastic foam could mean more fuel-efficient cars

Researchers have developed a way to make cheaper, lighter-weight syntactic foams at industrial scale, paving the way for more efficient, less costly products and vehicles. … “At laboratory scale, when you are mixing components in a flask, you can be careful and minimize damage,” says Nikhil Gupta, an associate professor of mechanical and aerospace engineering at New York University [Tandon School of Engineering]. “But at an industrial scale, producers have to make large quantities of material quickly, because time is money. Thus, breakage of these particles becomes much more problematic.”
