The automotive industry's transition from traditional rubber to advanced thermoplastics reached a milestone as the Society of Plastics Engineers (SPE) named the 2002 Jeep Liberty's Santoprene TPV glass run channel application its 2026 Hall of Fame Winner, recognizing an innovation that fundamentally changed automotive manufacturing. The groundbreaking application marked the industry's first use of Santoprene thermoplastic vulcanizate (TPV) for glass run channels — the extruded profiles in which car windows slide up and down — replacing ethylene propylene diene monomer (EPDM) thermoset rubber. The innovation delivered substantial weight reduction, manufacturing cost savings, improved performance, and material recyclability. Weight and performance benefits The TPV technology achieved weight savings of 30% to 50% compared to EPDM rubber, contributing to improved vehicle fuel efficiency. The reduction came through multiple design optimizations: TPV's lower density, thinner ...
