Stat-Tech™ TPE Static Dissipative & Electrically Conductive Thermoplastic Elastomers Stat-Tech™ TPEs are electrically conductive thermoplastic elastomers engineered to protect critical electronics from electrostatic discharge (ESD), and electromagnetic and radio frequency interference (EMI/RFI). Stat-Tech TPEs can be both injection molded and extruded, giving great design freedom for more complex geometries. Stat-Tech TPEs are well-positioned to perform in applications such as industrial conveyor belts and controllers, ADAS systems and electronic devices.

GLS™ TPEs with Antimicrobial Technologies This specialty line of GLS™ thermoplastic elastomers has imbedded antimicrobial additives that inhibit bacterial growth by 99.9% or more (log 3) and resist fungal growth to protect molded plastic parts. Tested against common bacteria and fungi, these TPEs with antimicrobial technologies have proven to protect the finished part from microbial and fungi growth on both textured and smooth surfaces. KEY CHARACTERISTICS • Protects finished part by inhibiting microbial and fungi growth • Extends useful life of finished TPE parts by controlling deterioration caused by mildew or mold fungus • Increases product durability, preserves surface integrity, and minimizes odors MARKETS & APPLICATIONS Suitable for high-touch surfaces and applications, GLS TPEs with antimicrobial technologies add value in the consumer, packaging and automotive markets.

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.

For example, overmolding a TPE grip onto a hand mixer can improve comfort. A few of the options you can add with GLS TPEs: 1. TPEs can provide unusual texturing, such as a bubble or ridged surface or even a leather look. 3.

Silicones and the standard TPEs traditionally used in cosmetic packaging present several tradeoffs. Good processability is a key benefit of chemically compatible TPEs. For more information on chemically compatible TPEs, download the application bulletin.
