Chomerics array of conductive elastomer compounds offers true flexibility in selecting appropriate material for applications on the basis of cost and attenuation required. 

Standard extrusions are hollow or solid strips from 0.71mm (0.028") to 50.8mm (2.0") wide flat ribbon with existing tooling in thousands of profiles. 

We also offer full-service fabrication for large and small volume requirements as follows;

• Cut-to-Length
• Spliced Joining
• Framed Assemblies
• Bonded Gaskets
• Die-Cut and Precision Washer cuts

Almost every Chomerics elastomer grade is also available in sheet form with thickness ranging from 0.51mm (0.020" ) to 3.18mm (0.125"). 

JHC specializes in providing gaskets die-cut to clients drawing requirements.
