From 160°C High Temperatures to Humid Environments: The Dual-Environmental Challenger of Conductive Tapes
In industrial-grade EMC shielding applications, stable conductivity under extreme conditions and reliable thick-layer bonding are both essential. The tesa 60257 grey conductive tape provides all-weather electromagnetic protection for heavy-duty equipment through its 250µm conductive woven carrier and three-direction isotropic conductivity.
I. Core Product Positioning
tesa 60257 is a conductive tape specifically designed for demanding environments. It is suitable for:
✔ Grounding industrial motor housings (withstands 160°C short-term)
✔ Electrostatic discharge in outdoor electronic cabinets in humid conditions
✔ Conductive fastening for high-vibration equipment (tear-resistant carrier)
✔ Bridging conductivity across large-gap structures (250µm thickness compensation)
✔ RoHS-compliant heavy-duty equipment manufacturing
