When closurelogic turned to Avient for material selection help, the team developed a GLS™ TPE (thermoplastic elastomer) based on a stable, low migration TPE with a lower processing temperature compared to competitive TPEs, thus resulting in even fewer volatiles. Lined with TPE, closurelogic caps have outstanding tightness for sealability of both one-way and refillable bottles, while maintaining good removal torque. Avient offers GLS TPE cap liner formulations that are suitable for aqueous, acidic and low alcohol beverages processed under ambient, pasteurized or hot fill conditions.

IMPROVE FINISH AND PERFORMANCE CHEMICALLY COMPATIBLE TPES FOR COSMETIC PACKAGING Functionality and differentiation are key when designing cosmetic packaging. Ability to add surface texture – Our injection molded TPEs are easily processed in commonly used, complex molds. Good processability – Cycle times for injection molded TPEs are typically faster than alternative materials, resulting in reduced costs with chemical compatibility performance.

reSound™ REC Recycled Content TPEs – AF 7210 Series Recycled TPEs for Automotive Interiors Sustainability continues to be a key driver in the automotive industry. They provide comparable performance to virgin TPEs, with good UV stability and meet vehicle interior air quality (VIAQ) standards for odor and fogging. KEY CHARACTERISTICS • Contains 51–59% recycled content, with a minimum of 37% from PCR sources, including closed-loop feedstock • Provides comparable performance to virgin TPEs - Good UV stability - Meets VIAQ standards for odor and fogging • Supports compliance with the ELV Directive • Provides a more sustainable alternative to virgin TPE grades and supports a reduction in product carbon footprint (PCF) • Can be injection molded and overmolded onto PP KEY APPLICATIONS The reSound REC TPEs – AF 7210 series has been developed for use in automotive interior applications such as cup holder mats, phone charging mats, peddle covers, boot/trunk lining, HVAC flaps and other center console parts.

Versaflex™ TPE materials offer great compression set properties for gaskets that need a long lasting seal, and also create durable speaker skins with a silky feel. These TPEs meet industry ingress protection (IP) standards, are overmoldable directly onto common speaker housing substrates, and deliver more design freedom than you’ve ever thought possible. Versaflex TPEs safely deliver on all of these requirements, while also accelerating production speed and reducing manufacturing cost. www.avient.com Copyright © 2020, Avient Corporation.

There’s a way to achieve both form and function by adding a soft-touch, thermoplastic elastomer (TPE) grip. But by adding a TPE grip to an outdoor product, the perceived value and selling price skyrockets. Some TPE formulas produce a more secure grip, or you can make use of a custom texture for improved handling.
