Abstract/Summary

Expanded polystyrene (EPS) poses a significant environmental danger due to its low recyclability and lack of reuse cases. Thanks to ITW – Global Tire Repair’s sponsorship, this study investigates the formulation, performance, and composition of three distinct levels of EPS tackifying dispersions including 0.7 wt%, 3.4 wt%, and 6.0 wt% EPS through peel testing, puncture testing, topographical analysis, and FTIR. Through the information gathered in this report, a new incentive for EPS recycling may be discovered.
