THE SOLUTION While researching other possibilities online, the company found Avient and requested additional information on its thermoplastic elastomers (TPEs). While evaluating several grades, the accessories company worked with Avient’s global color and additives group to develop a glow-in-the- dark solution. In addition to providing a custom green shade, Avient’s engineers had to ensure the glow-in-the- dark effect could match dedicated gamers’ extended periods of play.

In addition, the design included more traditional features, such as four small support feet on the underside of the mouse for low-friction, easy-glide operation. The Avient team worked carefully to develop a compound that could utilize existing tooling to avoid additional tooling costs. In addition, the profit margin on this product was about 30% higher than that of other models.

The performance of both Cesa solid and Hiformer liquid additives is effective at low concentrations in eliminating melt fracture (shark skin) and die buildup (die drool). Processors are looking to replace current process additives containing PFAS with non-PFAS fluorine-free solutions that exhibit performance characteristics similar to traditional fluoropolymer- based solutions. KEY CHARACTERISTICS • Reduces melt fracture leading to fast time to clear • Reduces die buildup • Improves process efficiency • Retains ability to seal and print • Available in both solid and liquid • Offers low concentration efficiency • Reduces power requirements • Does not interact with other additives APPLICATIONS • Blown film • Profile extrusion • Tubing and pipe extrusion • Wire and cable applications • Extruded sheet • Applications in both virgin resin and PCR Copyright © 2024, Avient Corporation.

Guided by their initiative to develop capabilities that provide additional protection for soldiers while reducing time and logistic requirements,1 the U.S. It’s portable enough to be airlifted into remote sites and provides quick protection for troops with no additional equipment support needed. These panels successfully encapsulate the bullet, preventing harmful ricochets and providing additional safety to the warfighter.
