Gaskets – Custom Extrusions
Dual durometer profiles for specific applications where generic gaskets may not work. Applications where these innovative compounds and profiles include but are not limited to:
- 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 not only necessary but critical.
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.
These extrusions exhibit 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.
Many of the materials available include:
- Close Cell EPDM Sponge and Solid
- Closed Cell Neoprene Sponge (available in UL 94 HB through UL 94 VO grades) and Solid
- Custom Colors
- Pressure sensitive adhesive and heat activated tape.
For specific applications contact us for the best possible design and installation of your custom extrusion.
