Forward-looking statements give current expectations or forecasts of future events and are not guarantees of future performance.  PolyOne’s chief operating decision maker uses these financial measures to monitor and evaluate the ongoing performance of the Company and each business segment and to allocate resources. Senior management uses operating income excluding special items, adjusted EPS, and working capital to assess performance and allocate resources because senior management believes that these measures are useful in understanding current profitability levels and that current levels may serve as a base for future performance.

Forward- looking statements give current expectations or forecasts of future events and are not guarantees of future performance. EBITDA and Adjusted EBITDA are non-GAAP financial measures that management uses in evaluating operating performance. Management believes this provides comparability of the performance of the combined businesses.

Learn how composite springs provide flexibility in prosthetic performance and design Manufacturer gains performance and sheds cost with advanced composites Antimicrobial technology, custom colors and performance additives in one masterbatch

Formulations that can resist chemicals and disinfectants, helping maintain performance of medical infusion and drug delivery pumps. Custom formulations can meet specific opacities, sealing requirements, impact performance, and align with ISO 6009 color standards. Vibrant, biocompatible colors for high-performance healthcare applications

High-Performance Flexibility Manufacturing these versatile, highly engineered products requires high-performing, flexible, polymeric, and biocompatible materials that must be tailored to meet physical properties, sterilization, coloration, and other performance goals. These flexible components need to safely enter and leave the body, travel complex pathways, and optimize performance.

These fibers reinforce a wide array of resin systems ranging from polyamides to higher-performance engineering polymers such as PEEK. Additive technologies such as UV performance enhancement or impact modification are also available to tailor a solution for your specific need.  Performance maintained at low and elevated temperatures

Both are developed to offer comparable performance to conventional density-modified solutions but with less reliance on virgin thermoplastics, supporting the circular economy and reducing carbon footprint relative to fossil feedstock resin alternatives.  Performance characteristics, including density, corrosion and chemical resistance, and mechanical performance, can be customized depending on application needs.   Dyneema®, the world's strongest fiber™, enables unmatched levels of performance and protection for end-use applications, including ballistic personal protection, marine and sustainable infrastructure and outdoor sports
