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.

Cable tie methods include longitudinal ties and cross braids. Cross braiding is further divided into transverse braiding and diagonal braiding. Longitudinal braiding is used for core wires that do not need to be stranded as a whole and do not require flexibility. Cross braiding is a high speed process with good flexibility. material from a vapor phase to a solid film.
Hot melt adhesive laminated aluminum foil films are divided into two types: aluminum/PE shielding film and aluminum/PVE shielding tape. They use MQ-40 polymer as heat sealing adhesive, which is non-toxic and environmentally friendly, complying with the latest version of EU RoHS environmental regulations. The other type is self-adhesive laminated aluminum foil with genuine EAA self-adhesive film, which ensures good heat-seal adhesion and long-term stability at lower preheating temperatures.
