POMMERLOCH, Luxembourg – June 17, 2020 – Today, PolyOne announced it is adding production of both post-industrial recycled nylon grades (Nymax™ PIR)  and bio-based thermoplastic elastomers (reSound™ OM) in Europe. reSound™ OM (overmolding) thermoplastic elastomers (TPEs) utilize between 40 and 50 percent bio-renewable content derived from sugarcane, and offer hardness levels and performance comparable to standard TPEs.

The composition of the Board is intended to reflect an appropriate mix of skill sets, experience and qualifications that are relevant to Avient’s business and governance over time. We annually evaluate the composition of our compensation peer group, giving specific consideration to company size, global presence, and specialty chemical focus. To continually reinforce our ongoing commitment to enhancing shareholder value, the general design for the 2022 awards was to vest one-third upon the later of: (1) achieving each of the following stock price hurdles and maintaining them for thirty consecutive trading days: 10%, 15% and 20% increase, respectively, over the initial grant date closing stock price of $52.64; and (2) the satisfaction of time-based vesting requirements that lapse one-third on each of the first three anniversaries of the grant date, generally subject to the Named Executive Officer’s continued employment.

Cesa™ Fiber Additives Light Stabilizers for Synthetic Fibers and Nonwovens Non UV-stabilized fibers exposed to sunlight can suffer color fading and molecular changes that degrade their chemical and mechanical properties, leading to fraying and breakages. The Cesa™ Fiber Additives portfolio includes light-stabilizing and UV-absorbing concentrates for the spin-dyeing process. Additional solutions can be offered on request for other synthetic fibers such as PLA or TPU.

Cesa™ Fiber Additives for heat preservation are the formulated additives to enhance the heat preservation performance of textiles with synthetic fibers according to the test standard GB/T 30127- 2013. Fabrics made with Cesa Fiber Additives can absorb more heat when exposed to simulated sunlight with the wavelength from 320 to 1100nm. This solution includes two grades, one for polyamide and the other for polyester fibers.

We continue to execute very well against a backdrop of macroeconomic challenges. Sustainable infrastructure solutions that increase energy efficiency, renewable energy, natural resource conservation and fiber optic / 5G network accessibility Net income from continuing operations – GAAP
