Dual Durometers combine state of the art profiles and high technology processing in the same profile with dissimilar materials. These two materials are cross-linked and cured together thus creating an inseparable bond. An example would be a Closed Cell Sponge combined with a 70 durometer solid within the same profile or two different color compounds within the same profile. This is a very complex process with Alloy Extrusions as a leader in the industry! APPLICATIONS

Where two separate colors are required in the same extrusion.
Where a soft sealing surface is required as well as a hard mechanical engagement.
Where a higher cost polymer is required on one surface but a lower cost polymer is sufficient on another surface.
Where ease of installation and low shrinkage is critical.

ELECTRONICS

Dual durometer profiles may be wrapped with conductive tape to provide extra stability for EMI/RFI shielded enclosures. The base of the profile provides a solid mounting platform for the sponge-sealing segment allowing low closure effort.

DYNAMIC SEALING APPLICATIONS

Mechanically attached flange seals for doors, windows, panels or any other aperture requiring open-close type movements for long life. These seals function well in many of the transportation, architectural, appliance, electrical and industrial markets.
