2-mil Aluminum Foil EMI Shielding
  • Superior EMI Shielding (1MHz - 20 GHz)
  • Many shape configurations
  • Flame retardant (depends on Jacket selection)
  • Intended for minimal Flex Applications
  • Low cost

Material Specification No. 3005

Raw materials are not sold separately, please contact the sales department for any special requirements.


SH1 Foil is a thin, lightweight shielding material that consists of a 1-mil Aluminum foil backed with a 1-mil Mylar (Polyester) film. It can be combined with most Zippertubing jacket materials and closure types to create a lightweight cable jacket with outstanding EMI shielding performance. The material is a general purpose shielding product that is ideal for use in protected areas like electronics racks and should not be used in areas where a great deal of flexing is likely to occur. It can be configured for Round, Flat and Rectangular cable shapes and is supplied with or without a sewn in 15 AWG braided Tin/Copper ground wire running the full length of the product. When using the SH1 Foil this EMI Shield material will be sewn to the selected jacket material and remain loose along one edge allowing the material to be easily removed from selected areas as desired. The SH1 Foil material is flame retardant but the final product flammability rating will be dependent on the outer jacket material and closure mechanism selected to create the final product.

Before using Zippertubing® products, the user shall determine suitability for the intended use, and user assumes all responsibility for improper selection. Published attenuation values of Zippertubing® shielding have been verified by laboratory testing of the respective shielding materials. Actual installed attenuation values may differ due to installation techniques and final assembly operation parameters which are beyond the control of Zippertubing®. Actual attenuation values can only be determined by the end user testing the completed assembly.
