HOW TPV OUT-PERFORMS EPDM IN ACOUSTIC PROPERTIES FOR AUTOMOTIVE SEALING

摘要

A comparative analysis of TPV vs. EPDM with respect to noise reduction is examined for automotive weatherstrip body sealing applications. Specifically, EPDM sponge is compared with JyFlex~TM, a TPV compound of equivalent stiffness. The study is performed using multiple acoustic tests (road and component), supported by FEA analysis as a diagnostic tool.
