Abstract
An electromagnetic shielding heat shrink tubing, particularly one employing a double-layer structure, features an outer layer of high-performance insulating polyolefin and an inner layer of silver-coated conductive coating. This allows it to achieve over 99% electromagnetic shielding across the entire EMI spectrum. Compared to traditional metal braided tubing, this electromagnetic shielding heat shrink tubing is not only lighter and more flexible and insulating, but it also securely wraps around cables, comprehensively enhancing its anti-interference performance.
