EST - Shielding Heat Shrink Tubing
Applications
This product features an innovative dual-layer construction, consisting of a high-performance polyolefin insulating outer layer and a patent conductive inner layer. It delivers over 99% electromagnetic shielding effectiveness across the full EMI frequency spectrum. Compared with traditional metallic braids, the electromagnetic shielding heat shrink tubing is significantly lighter, more flexible, and provides superior insulation, while ensuring a secure and conformal fit around cables to enhance overall interference suppression performance.
Operating Temperature Range
- Continuous operating temperature: -45˚C~125˚C
- Minimum shrink temperature: 84˚C
- Full recovery temperature: Above 120˚C
Color
Standard color: black (Other colors, special sizes, and cut pieces are available on request.)
Characteristics
- Shrink ratio: 1.8:1
- Flexible, highly flame-retardant construction
- Excellent physical and electrical performance
- Compliant with RoHS and REACH requirements
- Superior shielding effectiveness from 10 kHz to 6 GHz
