THE CHALLENGE Any military organization’s top priority is protecting soldiers, and one necessary measure is critical battlefield defense from enemy fire and explosive events. With our hardware fabrication capabilities and Avient’s knowledge of composite ballistic protection technology, we were able to create modular systems that reduce time and logistic requirements for our brave soldiers.” 1 https://www.erdc.usace.army.mil/Missions/Military-Engineering/Deployable-Force-Protection-Demo/ To learn more about ballistic resistant solutions from Avient, visit avient.com or click to request a quote.

Because the toothbrushes were molded in both clear and opaque resins, the team had to explore two different avenues—one that preserved clarity and one that retained opacity.

One of the key properties of thermoplastic elastomers supplied by GLS is hardness. The hardness of a material is often one of the first criteria considered when choosing a thermoplastic elastomer (TPE).

Recycled plastics can be used to create new products across several industries, but one brand owner in particular was looking to incorporate recycled plastics in their consumer applications. Additionally, for every one ton of plastic recycled, the customer saves planet Earth the equivalent of 1,000–2,000 gallons of gasoline.*
