A soft black thermoplastic vulcanizate (TPV) combining a low coefficient of friction with good bonding to TPV and EPDM rubber, in particular EPDM sponge profiles. This Santoprene grade offers easy processability due to a high shear thinning behavior for injection molding of complex geometries and excellent surface aesthetics, without surface bleeding after heat aging. Santoprene 121-40B260 TPV has been designed for soft corner molding and end caps of automotive dense and sponge weatherseals.
Key Features
• Specially formulated to replace thermoset EPDM rubber in automotive door-seal corner molding applications
• Designed for shorter processing cycle time compared to thermoset EPDM rubber
• Adheres to vulcanized EPDM rubber and TPV (dense and sponge)
• Built-in low COF properties
• Good flowability with excellent surface aspect
