HOME | Contents | Message from the CEO | About Us | People | Products | Planet | Performance | Metrics | Index Sustainability Report | 2022 10 Avient Protective Materials On September 1, 2022, we completed the purchase of the protective materials business of DSM (including the Dyneema® brand), now called Avient Protective Materials. Avient Protective Materials worked with offshore wind farms to develop low pre-tension mooring systems made from Dyneema® DM20. With the addition of Avient Protective Materials, we also have 4 sites with ISCC Plus certifications.

Pro Forma Financial Information The Company acquired Avient Protective Materials (“Dyneema”) on September 1, 2022 (the “Acquisition Date”) and sold the Distribution segment on November 1, 2022. To provide comparable results, the company references “pro forma” financial metrics, which include the business results of Avient Protective Materials for periods prior to the Acquisition Date, as if the transaction occurred on January 1, 2021 and reflect Distribution as a discontinued operation. Our formulation expertise supports material science decisions, while our processing expertise guides customers to use the materials properly.

The new ECCOH 5983 Formulation is developed to help prevent environmental stress cracking in low and medium-voltage armored power cables, protecting power supply and avoiding costly damage. Metal armoring is utilized within the cable structure to protect against cracking; however, as environmental temperatures fluctuate, the armoring and other cable materials expand and contract at different ratios, further increasing the risk of cracking. Dyneema®, the world's strongest fiber™, which enables unmatched levels of performance and protection for end-use applications, including ballistic personal protection, marine and sustainable infrastructure and outdoor sports
