Cuming Microwave C-RAM CS & CS-HT Space Cloth Sheet Stock With Controlled Resistivity and RF Loss

C-RAM CS and CS-HT are series of materials with controlled surface resistivity and dissipation factor. Both materials are based on a lightweight woven fiberglass cloth, which is coated with a carbon loaded coating yielding well controlled resistance and RF loss.

C-RAM CS and CS-HT are space cloth type materials exhibiting traditional woven fabric characteristics allowing air and liquids to pass through the material.

Standard C-RAM CS will tolerate continuous use through 215°F.

C-RAM CS-HT is made with a binder which exhibits high thermal breakdown, thus the material will withstand continuous use through 300°F and short time exposure up to 375°F.

C-RAM CS can be provided with a conductive surface, but preferably a nonconductive outer coating is applied for protection and performance consistency. For this reason C-RAM CS is tested and controlled by its insertion loss, measured with the material at a 0° incidence angle.

The following types of C-RAM CS and CSHT are available:

Nominal thickness is .010 in. to .015 in. Standard sheet size is 12 in. x 12 in. but can be supplied up to 36 in. x 48 in.
