TECHNICAL BULLETIN reSound™ BIO Thermoplastic Elastomers Customizable Bio-based TPEs reSound™ BIO TPEs are formulated utilizing between 35 and 60 percent bio-renewable content. Initially available in overmolding grades compatible with PP, all grades are formulated to achieve comparable performance to traditional TPEs. This expertise enables brands to meet sustainability goals while maintaining the mechanical properties of traditional TPEs.

To learn more about our wet grip TPEs, contact Avient at +1.844.4AVIENT (1.844.428.4368) or visit avient.com. The customized TPE offered excellent hydrophobic qualities and similar melt strength to PP while still maintaining its key mechanical properties. Ultimately, Avient customized a GLS™ wet grip TPE that outmaneuvered traditional materials—delivering dynamic hydrophobic performance, translucent aesthetics, non-abrasive comfort grip, and excellent UV protection.

Using phase barriers made of Avient’s OnFlex™ S HF, HF 7001, and Synprene or Synprene™ RT thermoplastic elastomers (TPEs) will help you deliver on that promise. Easier to install – Our TPEs are more flexible than nylon and flexible PVC, which makes the MCCB easier to install, service and inspect. Low moisture absorption – While nylon is water- absorbent and loses dielectric performance in the presence of excessive water, our TPEs exhibit low moisture absorption and maintain the necessary dielectric properties over the MCCB’s service life.

So we’ve developed the ideal TPEs for your infant care application, from materials that are durable and safe for baby contact to regulatory compliant grades and soft-touch solutions The food contact compliance statements are based on the composition of the TPE and cite any restrictions, limitations, food types, and/or specific migration limitations (depending on the regulation). Our GLS TPEs safely deliver on all of these requirements, while also adding comfort and enhancing consumer appeal.

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. Simpler production process – Overmolding Versaflex PKG TPEs is an effective method for simplifying a two-step process into a single step

Versaflex™ XP Wet Grip Thermoplastic Elastomer Typically, when TPEs get wet, the kinetic coefficient of friction (COF) performance is worse, resulting in a slippery surface. The Versaflex™ XP 2850 formulation is a specialty TPE developed to meet the challenge of wet environments, offering nearly double its dry kinetic COF when wet for better grip performance. KEY CHARACTERISTICS • Excellent COF performance (both wet and dry) • Outstanding abrasion and UV resistance • Easily colorable • Custom formulations available to achieve specific performance properties • Injection moldable (can be overmolded) and extrudable • Retains properties and performance when immersed in salt water MARKETS & APPLICATIONS This grip-enhancing TPE is colorable and customizable to meet the look and functional requirements of a broad range of consumer applications.
