Most fluoropolymers, other than PTFE and polyvinyl fluoride (PVF), can be melt processed using conventional thermoplastic extrusion or molding techniques. Fluoropolymers have high melting points and corresponding high processing temperatures and continuous use temperatures, depending on the specific product. At the lower end, polyvinylidene fluoride (PVdF) has a typical continuous use temperature of 300°F (150°C) and typically reaches 450°F (232°C) during processing3.

Reconciliation of Non-GAAP Financial Measures (Unaudited) (Dollars in millions, except for per share data) Senior management uses comparisons of adjusted net income from continuing operations attributable to Avient shareholders and diluted adjusted earnings per share (EPS) from continuing operations attributable to Avient shareholders, excluding special items, to assess performance and facilitate comparability of results. We also monitor earnings (defined as net income from continuing operations) before interest, taxes, depreciation and amortization (EBITDA) and adjusted EBITDA (EBITDA before the impact of special items) as a supplement to our GAAP measures.
