What is dual durometer?
Dual durometer, or co-extrusion, is the fusion of two or more materials of varying physical properties into a single extruded piece. An example would be a rigid part with flexible fingers that could be used as a gasket or cushion. Typically, the two materials are from the same family of polymers to ensure compatibility for adequate adhesion; however, in some instances dissimilar materials can be extruded together, providing adhesion can be obtained.
