Plastic to metal, steel to aluminum: The future of welding and lightweight vehicles

plastic manufacturing

Making vehicle structures out of a combination of metals and plastics could make them dramatically lighter, stronger, safer and more environmentally friendly than the all-steel or all-aluminum approaches that dominate today.

But how to quickly and cheaply join all those materials together has been a sticky problem. A University of Michigan lab is developing solutions.

New lightweight material is stronger than steel

New lightweight material is stronger than steel​

via MIT News

The new substance is the result of a feat thought to be impossible: polymerizing a material in two dimensions.

Using a novel polymerization process, MIT chemical engineers have created a new material that is stronger than steel and as light as plastic, and can be easily manufactured in large quantities.

The new material is a two-dimensional polymer that self-assembles into sheets, unlike all other polymers, which form one-dimensional, spaghetti-like chains. Until now, scientists had believed it was impossible to induce polymers to form 2D sheets.

Pandemic mask mountain sets new recycling challenge

by

via Phys.org.

Researchers in Australia want to transform single-use COVID masks into road material. In the United States, the protective gear is recycled into benches. And in France, they are reborn as floor carpets for cars.

Used to curb the spread of COVID-19, masks are exacerbating another pandemic: plastic pollution.

Researchers find how tiny plastics slip through the environment

by

via Eurekalert

Washington State University researchers have shown the fundamental mechanisms that allow tiny pieces of plastic bags and foam packaging at the nanoscale to move through the environment.

The researchers found that a silica surface such as sand has little effect on slowing down the movement of the plastics, but that natural organic matter resulting from decomposition of plant and animal remains can either temporarily or permanently trap the nanoscale plastic particles, depending on the type of plastics.

Scientists develop a truly recyclable plastic. Is the world ready for it?

by

via Fast Company

If we can’t ditch plastic, we can at least make it more recyclable—at least that’s what researchers at Lawrence Berkeley National Laboratory and the Department of Energy are proposing with a new material called PDK.

The average American generates 220 pounds of plastic waste each year. A vast majority of it is not recycled, even if you send it to a recycling facility. Most plastic ends up in a dump.

There are all sorts of reasons for this. Some recycling facilities don’t have the technology to sort plastic correctly. And for companies, it’s actually cheaper to make “virgin” plastic than to produce recycled plastic. Recycled plastic is far from perfect anyway. Generally produced by melting down old plastic, recycled plastic actually needs virgin plastic mixed in to keep its structure. An estimated 91% of all plastic isn’t recycled at all.

National Science Foundation Awards Grant to Rensselaer Polytechnic for Research into New Plastic

by

via Plastics Today

With the support of a $300,000 grant from the National Science Foundation, chemical engineers from Rensselaer Polytechnic Institute in Troy, NY, aim to develop a new polymer that can replace polystyrene (PS). While PS is inexpensive and easy to make, it is difficult to break down into its original components for re-use through a process called depolymerization. Founded in 1824, Rensselaer is America’s first technological research university.

IKEA’s plan to give plastic and polyester a second life

by

via Toronto Sun

It was just a little more than a year ago that IKEA Canada announced it would phase out all single-use plastic straws in Canada, nine months ahead of its global commitment to eliminate all single-use
plastics from its product range and restaurants by January 1, 2020.


It should not be surprising that this announcement got a lot of play — people really do care about this topic — but at the same time, only a smaller part of the retailer’s sustainability plans.

Extruder makers hopeful for strong 2018

by

via Plastics News

End market diversity is the blessing for manufacturers of extruders.

Extruders are used to make pipe and siding in the construction market, sheet and blown film in packaging and tubing for medical. Not to mention custom extrusion for everything from aerospace to writing instruments.

One slow market segment can be offset by another hot one, machinery officials said.

In construction, single-family housing starts were up 8 percent year to date through October, from the same period a year ago, on pace to hit an annual rate of 877,000 in 2017, according to the U.S. Census Bureau. Starts are beginning to get a boost from reconstruction activity from Hurricanes Harvey and Irma.

Companies focus on business, not NAFTA, at Plastimagen

by

via Plastics News

Mexico City — The increasingly sharp rhetoric over the future of the North American Free Trade Agreement wasn’t exactly center stage at Plastimagen. Visitors and exhibitors said the focus was definitely on business.

But still, like the hum of the machinery running in the exhibition halls, it was constantly in the background and could not be avoided.
