Meet the EKI 424

    After the EKI 400 featured in our previous video, it is now time for the next product in the series: the EKI 424. Just like the EKI 400, this is a closed-cell EPDM cellular rubber, ideal for sealing applications both indoors and outdoors.

    What makes th


    What makes the EKI 424 different?

    The key question, of course, is: what makes the EKI 424 different from the EKI 400? The 424 has a lower density, making it much softer, more flexible, and compressible up to 90%! This makes the material particularly suitable for airtight construction. These differences may seem small on paper, but they can make a significant difference in quality and durability for the customer’s final application.

    In this video, our show host Ids Heezen explains more about the features and applications of the EKI 424.
