Eastman and Lubrizol Collaborate To Enhance TPE Overmolding Adhesion With Sustainable Materials
Rhea-AI Summary
Eastman and Lubrizol have partnered to enhance the adhesion strength of thermoplastic elastomers (TPEs) overmolded onto Eastman's Tritan™ copolyester TX1501HF.
The collaboration underscores the significance of overmolding in manufacturing, aiming at improving product performance and aesthetics in consumer goods. Utilizing sustainable materials, Tritan™ Renew and Lubrizol's ESTANE® ECO TPU, the companies optimized key TPE processing variables such as mold temperature and barrel temperature, achieving a 124% improvement in adhesion strength.
Further enhancements were noted with Lubrizol's ESTANE® ECO TPU grades, which displayed the highest peel strength values (>310 N). These findings offer valuable guidance for engineers and manufacturers, paving the way for innovative product designs using recycled content.
Attendees at NPE2024 in Orlando, Fla., can witness these materials firsthand and gain deeper insights through a joint webinar on June 12.

KINGSPORT, TN and WICKLIFFE, OH / ACCESSWIRE / May 14, 2024 / Eastman and Lubrizol have successfully partnered on improving adhesion strength of thermoplastic elastomers (TPEs) overmolded onto Eastman Tritan™ copolyester TX1501HF. The collaboration stemmed from a mutual recognition of overmolding's importance in manufacturing while delivering improved product performance and aesthetics in consumer goods when using Eastman's sustainable material, Tritan™ Renew, and Lubrizol's ESTANE® ECO, renewably sourced TPU.
The companies researched how specific processing variables impact the adhesion strength of overmolded samples produced through 2K injection molding. The study's findings are believed to be applicable across various TPE and substrate combinations. This is of particular interest when mechanical interlocks cannot be used, and material changes are not feasible but improvements in adhesion strengths are desired.
By optimizing key TPE processing variables like mold temperature, pack and hold time, and TPE barrel temperature, the research team achieved a notable
"This was a unique opportunity for two leading material companies to leverage sustainable multi-material solutions that enable customer innovations and expand the limits of consumer product experiences," said Vince Haas, Lubrizol's engineered polymers senior business director.
"This effort has advanced our understanding of overmolding and TPEs, providing valuable guidance for engineers and manufacturers looking to improve overmolded product strength," said Courtland Jenkins, Eastman's commercial director for engineered solutions. "These findings open doors for new and innovative product designs, particularly when using recycled content."
