Avient launches new signal-transparent TPE material for 5G high-speed transmission

Avient today announced two patent-pending Versaflex™ CE thermoplastic elastomers (TPEs) for 5G applications
.
The new Versaflex™ CE 3140 formulation is transparent to signals, delivering superior dielectric constant and low signal loss performance at high frequencies for better high-speed transmission and connectivity
.

Consumer electronics manufacturers are demanding better performance because the signals are shorter at 5G's high-end millimeter-wave (mmWave) frequencies
.
They face interference from trees, windows and even phone casings that can cause transmission problems for mobile devices
.

Therefore, Avient has introduced these TPE materials to improve signal transmission at millimeter-wave frequencies
.
Higher frequency ranges are required for faster data transfer, higher data capacity and lower latency (i.
e.
data transfer time)
.

The new transparent Versaflex CE 3140 TPE targets accessories such as casings for cell phones and other 5G mobile devices
.
Compared to standard TPEs, they offer lower dielectric constant (Dk) and dissipation factor (Df) performance, resulting in reduced signal degradation
.

Matt Mitchell, Director of Global Marketing, Avient Professional Engineered Materials, said: “As device makers roll out 5G-compatible products, phone case makers need materials that facilitate mmWave transmission to maximize signal performance
.
Signal quality is critical to access to 5G devices.
The benefits are paramount
.
Our specialty TPEs for 5G transparency provide phone case manufacturers with advanced solutions that allow them to differentiate their next-generation products and delight end users
.
"

Versaflex CE 3140 grades are available worldwide, injection molding and overmolding to PC, ABS, PC/ABS and COPE
.
They are a natural color thermoplastic elastomer that can be easily colored to match design specifications or brand preference
.
These TPEs are the latest additions to Avient's growing portfolio of solutions with enhanced dielectric properties and capabilities for 5G applications
.

Tech Note: Both Versaflex CE 3140 TPE grades are designed to exceed the industry benchmark for phone cases less than 2.
5 Dk at 37 GHz
.
Measured at 40 GHz, the 65 Shore A grade offers 2.
49 Dk and 0.
024 Df, while the 90 Shore A grade shows 2.
54 Dk and 0.
021 Df
