What is a TPE? Some tests are performed on injection molded plaques, while others are performed on extruded plaques. TPE

The injection takes place between the end of the extruder, or melt-pipe, and the spin head. Multiple color productions – several injection points possible on a single extruder​ Rapid color changes: No extruder contamination and easy color-on, color-off operation increases color change speed

Weight reductions between 15 and 30% can be reached in standard monolayer and co-extruded applications. Building & Construction Chemical foaming agents create an especially fine-celled foam structure in extruded goods. This cellular structure results in weight reductions of 15 to 30% in films and sheets and 20 to 40% in pipes, profiles, and boards.

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.

GLS™ TPE AUTOMOTIVE SOLUTIONS IMPROVE VEHICLE AIR QUALITY WITH TPEs FOR AUTOMOTIVE HVAC FLAPS Vehicle interior air quality in passenger vehicles and strict automotive OEM standards have driven our advancement of these low VOC, low fogging TPEs for use in heating/ventilation/air conditioning seals. GLS automotive TPEs are designed to improve driver and passenger safety and comfort. This industry-leading TPE technology reduces volatile organic compounds (VOCs) by 50% and fogging by 35% versus existing TPEs for HVAC applications. www.avient.com Copyright © 2020, Avient Corporation.

TPEs were determined to be most susceptible to microbial attack under the appropriate environmental conditions. Physical and mechanical property testing was also performed on extruded pellets and/or specimens prepared from injection molded plaques. These results made TPEs an attractive candidate for modification with antimicrobial additives for the preser- vation of the TPEs in their end product use and for fur- ther efficacy studies.

These are high clarity TPEs with high tensile and tear properties. These TPEs have good processability. Surface smoothness of both injection molded and extruded products is affected by the rheology and interface shear stress of the system.

Offering good flow properties and faster cycle times, the Dynalloy portfolio can be easily colored for use in a variety of applications, whether extruded, injection molded or extrusion blow molded. Selecting the Right TPE TPEs vs.

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.

On start up, retract the extruder and air purge it well before attempting to fill the mold. 24 PROCESSING CONDITIONS Introduction This section describes general processing guidelines for GLS TPEs. Injection Speed If possible, profile the injection speed to fill the runner system rapidly and then slow down after the material starts flowing through the gate and into the cavity. If the injection unit is equipped with a profiled pack and hold phase, it can be used to reduce the velocity and pressure to the runner.
