Reuse or Recycling of Thermosets: Interesting Approaches Emerging

Jeff Gotro, Ph.D

Thursday, May 23,  Webinar at 6:00 PM Pacific time

Abstract

Thermosetting polymers are widely used due to their high thermal stability, good mechanical properties, and ease of processing. The fully cured crosslinked network both provides outstanding thermal stability and poses challenges with regards to end-of-life. Unlike thermoplastics, cured thermoset resins and composites are not easily recycled and subsequently re-used (such as remelting a recycled PET water bottle). There are many emerging approaches to chemically recycling thermoset resins. The webinar will present an overview of the current approaches to address the end-of-life considerations in thermoset materials. One promising approach is to incorporate dynamic covalent bonds into the thermoset backbone. Covalent adaptive networks are commonly called vitrimers (term coined by Leibler in 2011). Vitrimers allow for reprocessing of fully cured materials. Another approach is to use a cleavable linkage in the hardener used in epoxy chemistry called Recyclamine® (Aditya Birla). Recyclamine® Technology is a platform chemistry with multiple unique amine curing agents containing specifically engineered cleavage points at cross-linking sites, which, under pre-defined conditions, convert thermosetting epoxies into thermoplastics, thereby enabling recycling. The presentation will cover the history, current approaches, and future work addressing end-of-life considerations in various types of thermosetting systems.
