Dual Durometer Rubber Extrusions

What is dual durometer rubber extrusions?

It is a co-extrusion process that fuses two materials of different physical properties into one uniform or consistent cross section. The most common of these extrusions is the combination of a rigid material, for strength, with a soft or flexible material, for function, into various one-piece profiles.

What are the advantages of dual durometer rubber extrusions?

By joining two materials of different physical properties, structural integrity and flexible function can be combined into one part. For example, when a rubber gasket must be attached to a metal part to provide a closure seal, a dual durometer rubber extrusion combines both functions into one piece, which significantly reduces assembly costs while enhancing performance and function.

Purpose and Application

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.
