Forward Looking Statements POLYONE CORPORATION 3  This presentation includes the use of both GAAP (generally accepted accounting principles) and non-GAAP financial measures. The non-GAAP financial measures include: adjusted EPS, Specialty platform operating income percentage, adjusted operating income, and return on invested capital Below is a reconciliation of these non-GAAP financial measures to their most directly comparable financial measures calculated and presented in accordance with GAAP for each fiscal year end.

For added convenience, they can be combined with color but also with other additives, such as flame retardants, antistatic or laser marking additives, into a single combination masterbatch. They contain non-halogen and non-antimony additives and don’t alter mechanical properties.

Homepage // News Center // Avient’s Newest Trilliant™ HC Materials Stand Up to Disinfectants Better Than Alternative FR Polymers These materials feature improved chemical resistance to trusted hospital-grade disinfectants over other flame-resistant (FR) polymers such as PC/ABS, PC/PET, and copolyester. Using a method adapted from ASTM D543 for ESCR (environmental stress cracking resistance), results versus alternative FR materials demonstrate superior mechanical and aesthetic property retention, and prevention of cracks and crazing after exposure to leading healthcare disinfectants* such as Virex® Tb, CaviCide™, Vesphene® IIse and Super Sani-Cloth®¹.

CASE STUDY: BERGAMID™ POLYMER FORMULATIONS & GLS™ TPES Ch all en ge A cc ep te d. Designers conceptualized a new, larger version of the Soldier’s model, including 10 tools, a lock blade that can be opened with one hand and, importantly, a non-slip handle manufactured from a combination of hard and soft thermoplastics. Achieving the non-slip handle Victorinox envisioned required a soft material for the new grip areas that would chemically bond to a rigid polymer underneath.

The recently launched Resilience™ LS material was chosen for its long-term color hold, UV stability and thin-wall 5VA flame retardance, more than meeting technical requirements for the Nuvi light. Rigid vinyl’s inherent flame retardance and UV resistance minimize the need for additives, reducing expense while maintaining protection for the LEDs, electronics and aesthetics.
