DSM Dyneema demonstrates potential to turn used soft armor vests into usable new products

Continuing its ‘Greenest Strength’ mission, DSM Dyneema provides an example of a creative way to re-use material from out-ofservice soft armor vests.

Dyneema UD (Uni-Directional bullet resistant sheet) is a key ballistic ingredient for best-in-class life protection applications like vests, helmets, and inserts, protecting soldiers and law enforcement officers. Compared to alternative materials, Dyneema fiber offers low carbon footprint per unit of tenacity. Since solutions with Dyneema UD require less material to achieve a given performance and have a high durability and long service live, a lowest carbon footprint in application lifetime is the result. Over the last years DSM Dyneema has further improved its environmental footprint in amongst others its manufacturing processes and is committed to continue the path.

DSM Dyneema is now also examining ways for body armor manufacturers and end-customers to reduce waste from end products made with Dyneema UD material. Waste material from ballistic sheets is generated in two ways. One is the off-cuts from Dyneema UD sheets when making the end-products like a vest. The other is when the protective article is taken out of service.

For the concept presented at Milipol, DSM Dyneema worked together with Marc Meijers, designer at DenimX. This resulted in prototype design table made with a combination of re-used Dyneema UD sheets and DenimX. DenimX has a process that converts used clothing, such as combat uniform and textiles into thin sheets.

Making the table involved shredding the used ballistic soft armor panels and offcuts, then pressing the material into flat sheets. This material is then used as input into an alternative value chain.

“By breathing new life into used vests, we can support and encourage a circular economy,” says Dirk Louwers, global marketing director Life protection at DSM. “By seeking ways to re-use ballistic protection materials into new applications, vest manufacturers and end-users such as the police or military may avoid having to dispose of offcut waste or used vests.”

“The table follows the re-using principle, using panels made of shredded Dyneema UD finished with blue or desert camouflage fabric,” says Marc Meijers, DenimX. “It’s a perfect illustration of potential of re-using Dyneema UD into a new product, and will help inspire more designers to explore alternative ideas.”
