Polytetrafluoroethylene film laminated aluminum foil
Aluminum/Polytetrafluoroethylene shielding tape is known for its shielding, high elongation, and airtight properties, making it ideal for the wire and cable winding industry. It has excellent dielectric properties and can be used on uneven surfaces. This polymer compound derived from polytetrafluoroethylene has excellent chemical stability, corrosion resistance, sealing properties, high lubricity, electrical insulation and good aging resistance.
Our PTFE tapes are favored for many commercial and industrial applications because they are excellent insulating tapes for high temperature and high dielectric applications. In addition, these PTFE insulating tapes have extremely low friction and non-stick properties, making them suitable for a wide range of mechanical applications.
Unlike metals, shielding laminates are non-conductive at their core. While metals such as copper are inherently conductive, shielding laminates formed from non-metals are ideally suited for use as insulation or signal shielding materials that do not respond to electric fields and resist the flow of charge.
Shielding laminates consist of at least two materials whose combined performance exceeds that of their individual components. In our context, we refer to shielding laminates consisting of both metals and non-metals, usually involving a combination of PET, PP, PI, PPS, PTFE with metals such as copper and aluminum.
