“A Rheological Approach to Liquid Silicone Resins”
Richard Hanzlik, Applications Engineer, Alpha Technologies. Richard is also our 2022 Paul Glasgow Memorial ORG Member Scholarship Award winner.
The market for silicones and Liquid silicone resins is predicted to grow rapidly over the coming years. These materials can be extremely useful due to their unmatched optical clarity, chemical/ thermal stability, and ability to be injection molded into complex structures. However, optimizing formulations and process conditions can be a bit of a guessing game. The question “what is this silicone’s viscosity?” is a frequently asked one, and the answer is, “it depends.” In this observational study we will evaluate how a Rubber process analyzer can be used to predict the viscosity of LSR’s across a range of shear rates, temperatures, and states of cure.
“Sustainable EPDM Rubber, Expanding the Keltan® Eco Family”
Pete Spanos, Sr. Technical Manager, Arlanxeo North America.
Keltan® Eco, a bio-sourced EPDM with a 10-year commercial history, can be a part of the solution when it comes to the challenge of sustainably produced rubber products. In addition, we explore how a new approach based on ISCC+ certification is helping meet sustainability goals.
“What Can Gummy Bears Teach Us About Biological Elastomers?”
Justin Barone, Biological Systems Engineering, Center for Soft Matter and Biological Physics, Macromolecules Innovation Institute, Virginia Tech
Many organisms utilize biological elastomers for efficient motion. Biological elastomers are very efficient because they are able to return a large portion of an imposed strain energy. Biological elastomers do not exist by themselves but instead are surrounded by water and other molecules like sugars and salts. The surrounding environment can affect the biological elastomer performance. Here, results are presented that show different sugars can affect elastomer modulus and efficiency. The studied biological elastomers can be used to construct bioinspired devices that respond to their environment over time.
