Abstract:

In this study, the self⁃lubricating thermoplastic vulcanizate (TPV) materials for automotive applications were investigated, focusing on friction coefficient, substrate adhesion, and physical properties of various lubricant formulations. Experimental results demonstrated that TPV compounds incorporating 5.0 phr (parts per hundred rubber) of high⁃molecular⁃weight polydimethylsiloxane exhibited optimal performance, achieving a surface friction coefficient of ≤0.75 while maintaining excellent bonding strength and mechanical properties. These characteristics make the developed material particularly suitable for automotive glass trim applications, offering significant potential for improved performance in demanding decorative applications.
