TOUGH ENOUGH TO PROTECT THE POWER GRID MODULAR BALLISTIC PROTECTION MADE POSSIBLE WITH COMPOSITES THE CHALLENGE Recent attacks on U.S. electrical substations across the country provide stark reminders that our nation’s power supply remains a primary target for criminals focused on harming our country and security.1 The call to action is evident: we must continually improve the physical and technological infrastructure protection of our nation’s energy supply. Avient and Southern States worked together to develop a modular design using GlasArmor ballistic panels. Using GlasArmor panels, Ballisti-Wall® and Ballisti- Cover® solutions enable utility companies to add a superior level of protection to critical components and meet FERC security requirements within a modular, adaptable construction. 1 https://www.nbcnews.com/news/us-news/three-substations- attacked-washington-state-rcna63214 2 https://www.ferc.gov/sites/default/files/2020-04/E-4_10.pdf © 2023, All Rights Reserved Avient Corporation, 33587 Walker Road, Avon Lake, Ohio USA 44012 To learn more about Avient’s advanced composite solutions, visit www.avient.com/composites.

Retirement Savings Program will receive a separate voting instruction card. Jellison began his career with the Donnelly Corporation, a publicly traded international automotive parts supplier, where he served in several senior leadership roles, advancing to Vice President of Finance. Delivering 7 consecutive years of adjusted earnings per share expansion, driven by record levels of profit and profitability, has created shareholder value.

Meet targeted cost-performance requirements – The selected resin must offer significant savings over the current LCP/carbon fiber formulation through material and/or manufacturing savings, thus enabling penetration of the low-cost computer market with a competitive connector. THE SOLUTION Because they knew Avient could help, the connector company’s design engineers invited Avient into the development process. In addition, Avient’s global presence supported the manufacturer’s needs across the globe, saving time and money while ensuring quality, consistency and reliability.

A 1:1 wall thickness will produce sink and cause stress where the ribs connect with the main wall. For example, this can be done by using inserts with thermal expansion rates matched as closely as possible to the polymer used to mold the boss.

Evaluating a metal substitution involves two primary factors: 1) the difference in processing methodologies, and 2) the material capabilities. Though the upfront tooling costs can be high, the investment can yield a life expectancy of 100,000 to over 1 million cycles. HOW SUPPLIERS CAN HELP EVALUATE MATERIAL TRANSITION Successfully using composites goes beyond simply swapping one material for another.

Manufacturers save time and labor by eliminating the need for peel ply or other surface preparation such as grinding or abrading, while achieving superior adhesion compared to these typical processes. KEY CHARACTERISTICS • Improves bonding performance of epoxy adhesives in installation of pultruded parts • Eliminates need for surface preparation with abrasion or removal of peel ply layer prior to application of adhesives • Reduces overall system costs by saving time and labor on secondary processes • Enables replacement of mechanical fasteners with epoxy adhesives for improved fatigue performance and reduced weight • Simplifies manufacturing processes and reduces part complexity PRODUCT BULLETIN www.avient.com Copyright © 2020, Avient Corporation.
