Edgetek™ Toughened PPA Formulations TECHNICAL BULLETIN The Edgetek™ Toughened PPA series consists of heat-stabilized, impact-modified polyphthalamide (PPA) formulations with low moisture absorption. These robust materials also incorporate heat stabilization to maintain tensile strength and tensile elongation properties for long- term thermal aging up to 120°C. KEY CHARACTERISTICS • High-temperature performance • Excellent impact resistance • Decreased moisture absorption compared to PA66 • Heat stabilized for long-term thermal aging • Enhanced chemical resistance • Customizable formulations in filled and unfilled grades MARKETS & APPLICATIONS The combined performance characteristics make Edgetek Toughened PPA ideal for a range of rigid engine applications.

Cesa™ Raise Heat Stability Modifier for APET Packaging Cesa™ Raise is a heat stability modifier specifically designed for amorphous polyethylene terephthalate (APET) thermoformed packaging. The technology addresses the limitations of traditional APET thermoformed cups and containers, which can only be used up to 60°C, by increasing its heat stability to up to 100°C. MARKETS & APPLICATIONS • Thermoformed, APET food packaging, including: - Hot steam sterilization - Hot fill - Microwave use • Polyester • Sheet extrusion & thermoforming KEY CHARACTERISTICS • Suitable for hot steam sterilization, hot fill, and microwave applications • Ideal for food-grade containers with high rigidity and improved gas barrier • Can withstand temperatures up to 100°C • Available in both transparent and opaque options • Processable on existing thermoforming lines with heated molds KEY BENEFITS • A fully circular monomaterial, up to 100% rPET polymer content • Promotion of the circularity of PET and the resulting packaging is possible • Helps customers to comply with the Packaging and Packaging Waste Regulation (PPWR) that demands recyclability of all packaging with binding PCR content targets by 2030 • Demonstrates improved productivity in comparison to CPET during thermoforming • Helps avoid possible EPR fees or penalties on difficult-to-recycle packaging PRODUCT BULLETIN Copyright © 2025, Avient Corporation.

COOKWARE MANUFACTURER A I R F R Y E R W I N D O W • Clear, FDA food-contact compliant material that can be run through a dishwasher • Able to withstand long-term steam and heat • Allows injection molding of a complex shape with aesthetics that convey cleanliness and quality • Added concentrate to a natural PES material allowing it to retain clarity and aesthetics in an FDA-compliant solution • Enabled material to withstand sterilization and maintain continuous heat resistance • Provided a more pleasing appearance that could command a greater price point due to perception of higher quality Colorant Chromatics™ PESU Concentrate KEY REQUIREMENTS WHY AVIENT?

They provide excellent resistance to heat, oil, creep, and abrasion for durability – which can help reduce the risk and rate of material degradation over time – plus high extrusion speeds and ambient curing for additional processing advantages and efficiencies.

By replacing aluminum with Therma-Tech™ thermally conductive polymer in the heat sink,manufacturers can significantly reduce total part weight and optimize production and logistics.

In response, PolyOne Corporation (NYSE: POL) has developed new Geon™ Bold vinyl materials with dark, rich colors that stand up to the elements, especially heat build up, without losing their vibrancy or performance.

Compared to other natural fiber reinforced solutions, reSound NF materials will offer mechanical property improvements of more than 20% for tensile and flexural properties, 10°C to 20°C higher heat deflection temperature, and an increase of more than 50% in impact strength.
