TIER 1 AEROSPACE SUPPLIER S E A T I N G S T R U C T U R A L C O M P O N E N T • Reduce weight to improve fuel economy • Pass FAA flame, smoke, toxicity requirements • Meet structural requirements • Simplify manufacturing process • Lowered weight ~40% versus aluminum while maintaining the strength performance properties • Formulated a PES material to satisfy flame, smoke, toxicity (FST) standards for commercial aircraft • Passed and/or exceeded customer’s impact testing specifications • Provided an injection moldable hybrid glass/carbon fiber solution that enabled lower viscosity and better processability for thin wall parts Complēt™ Long Hybrid (Carbon + Glass) Fiber Reinforced PES Composite KEY REQUIREMENTS WHY AVIENT?

Cosmetic brands COSMETIC BRANDS C O V E R O F A I R C U S H I O N P O W D E R C O M P A C T • Low coefficient of friction (COF) to balance the opening pressure and sealing performance • General FDA compliance • Good chemical resistance and barrier protection to water and oxygen • Overmold to PP with good compression set • Delivered chemically resistant material with excellent sealing properties and good resilience to achieve requested performance • Provided onsite technical support to improved injection speed and achieve good bonding performance • Offered a material solution that could be leveraged across the customer’s global cosmetic brands Custom Versaflex™ TPE KEY REQUIREMENTS WHY AVIENT?

To do so the following procedure was carried out: • Preforms were produced by dosing 0.09% of Avient Fortis Amber-1 and 4% of our nylon- based oxygen scavenger Amosorb SolO2-2 • Preforms were ground down to a coarse granule size (~2mm) using a Retsch mill • The coarse ground preforms were crystallized in a vacuum oven at 160°C before drying the material in a PET drier at 160°C for approx. 4 hours • This material was then injection molded and blown into bottles with a) 50:50 dilution with Virgin PET with no color and b) 50:50 dilution with Virgin PET + Fortis Amber-1 at 0.045% Figure 2. Bottle B was produced utilizing 50% flakes of the original bottles, which were crystallized and dried before being diluted with 50% virgin PET to inject new preforms and blow bottles.
