Dual durometer extrusions can serve a variety of purposes. Most often, the harder material serves as means of attachment, and the softer compound completes the seal. Sometimes, however, co-extruding polymers is done for cosmetic purposes. There are many ways to get creative when designing a seal— using multi-color, multi-durometer, notches, holes and PSAs. You can mix and match, or, put them all into one package. Contact us today and get more information and let us help start on your new project.
