PHONE CASE MANUFACTURER P H O N E C A S E • Formulated TPE with 43% bio-based content plus favorable UV resistance and vibration damping performance compared to standard TPE • Received radiocarbon (C14) international certificate for bio-based content • Provided excellent bonding ability with good aesthetics • Matched design specs with an easily colored material using traditional TPE colorants reSoundTM OM TPEs WHY AVIENT?

In many cases, TPEs are chosen for products over rubber because of their flexibility, versatility and recyclability. There are commonly known blends, such as material for a phone case or a fitness wearable. Unless you are a polymer expert, it’s challenging to know which type of TPE is the best fit for your use case.

Digimat for long fibre reinforced materials Advanced simulation captures part performance for fibre reinforced thermoplastics Comparing the results of isotropic material data to anisotropic material data Case study https://hexagon.com/ Figure 2: Digimat material model workflow when coupled with an FEA solver Manufacturing Intelligence hexagonmi.com2 Solution Avient leveraged Digimat to reverse-engineer material data based on the microstructure, tensile test data, and micro-mechanical modelling. Results & benefits Avient has applied the Digimat material model to two different load cases, a flexural test and a tensile test. The case study shows that by utilising the 3D suite simulation and comparing to real-world testing, Avient is equipped to more accurately interpret the data to help solve its customers’ toughest application challenges
