These days, everyone is talking about sustainability, while products also need to get lighter and lighter. Traditional foam technology hasn’t really been updated for decades, so supercritical foaming has quickly become the new darling of manufacturing. Vietnam’s manufacturing power has surged in recent years. Not only is its location strategically favorable, but costs are also…

When we talk about “Pebax Arkema,” the focus isn’t on how technical the name sounds, but on how it takes polymer structures from the lab and translates them into the lightness and rebound athletes feel underfoot. This chain that runs from molecular design all the way to foamed midsoles works like a cross-disciplinary language of…

In the running shoe world, discussions about EVA (Ethylene Vinyl Acetate) and PEBA (Polyether Block Amide) have long been a tug of war between material science and runner experience. A few years ago, you could roughly guess how a shoe would feel just by knowing its midsole material: EVA was steady and a bit dull,…

Walk into any big supermarket, sports shoe store, or medical supply shop, and you’ll notice that foamed cushioning materials are everywhere behind the products. The reason is simple: they bring together light weight, cushioning, and design flexibility. Even if you open up some industrial products, like cars or airplanes, you’ll find plenty of foam inside…

Lightweight, eco-friendly, and high-performance. These features are reshaping the design logic of polymer materials, and supercritical foaming technology is at the heart of this shift. It is not just a process innovation but also opens up new possibilities for industries like footwear, packaging, and automotive. Here’s a look at the basics of supercritical foaming, how…
