Homepage // News Center // Avient Extends Recycled TPE Portfolio with Grades Containing up to 60% Recycled Content, Supporting Global Customers Avient’s new reSound™ REC GP 7820 TPE grades highlighted at Fakuma 2024 can be used for overmolded components in consumer electronics, grips for razors and personal care products, and handles for bicycles and power tools The new reSound REC GP 7820 TPE grades are available in hardnesses ranging from 40 – 80 Shore A.

Typical applications are surgical instruments and thin walled tubing • Brilliantly colored: Proven expertise in coloring high temperature polymers, in both transparent and translucent shades, including bright whites, special effects and other hard-to-achieve colors

Our manufacturing capabilities and collaborative solutions- based technical services have been trusted for decades to create specialized and purpose-engineered composite rods, tubes, and custom shapes.

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.

Homepage // News Center // Pump Up the Volume on Portable Audio Speakers With New Versaflex™ TPEs from PolyOne Our new Versaflex™ CE TPE grades combine durable aesthetics with extreme protection from outdoor environments. ™ TPEs vs.

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.
