Commercial Grade Conductive Heat Shrinkable EMI Cable Shielding System
Silver Plated Copper CHO-SHRINK 1120 is engineered for commercial EMI cable shielding applications, offering low-cost, lightweight, 360° EMI shielding for cables, transitions, connectors, and terminations. Its easy application reduces assembly costs and ensures a professional-looking, reliable EMI shielding solution for electronic equipment. The system, comprising polyolefin heat shrinkable tubing, connector boots, and transition pieces, is coated with Chomerics’ unique silver-plated copper filled coating. CHO-SHRINK 1120 simplifies the assembly of complex cable wiring harnesses using conventional heat shrink tubing heating devices, providing excellent shielding and significant weight savings compared to traditional metal braid systems. Additionally, it offers environmental protection against dust, moisture, and contaminants. The flexible coating remains intact even after maximum shrinkage, supporting necessary cable routing. For easy repair or rework, simply cut off the old material and install new material. Ideal for medical device electronic assemblies, automotive cable assemblies, laboratory equipment, medical electronics, and telecom cabling, CHO-SHRINK 1120 provides reliable EMI shielding with the added benefit of silver’s antimicrobial properties.
