Polyester tape has transformed from a conventional auxiliary material to a crucial supporting function in high-end manufacturing in the industrial materials industry because of the special qualities of its base material and its adaptability in various processes. Polyester tape, in contrast to regular tapes, is made primarily of polyethylene terephthalate (PET). It may satisfy a range of requirements, from vehicle protection to electronic insulation, by using unique production techniques and adhesive combinations.
Polyethylene terephthalate (PET) is the raw ingredient used to make polyester tape, which is then mixed with various adhesives.
Broad temperature resistance and flexibility to meet a range of application needs: Polyester tape can withstand temperatures between 180°C and 220°C for an extended period of time.
High tensile strength and abrasion resistance: The polyester base material has a high tensile strength and a high resistance to tearing, which means that it won't break or fracture even when exposed to friction or outside forces. This feature makes it useful for wire harness fastening, packing, and bundling, and it's especially appropriate for applications that need to be exposed to external forces for an extended period of time. Various adhesive methods to satisfy various bonding requirements: Many adhesives, such as silicone and acrylic adhesives, can be utilized with polyester tape. While silicone polyester tape offers better resilience to high temperatures and adhesive residue, acrylic polyester tape provides long-lasting adherence and is appropriate for typical industrial bonding.
Outstanding chemical resistance and insulation: The polyester base material itself has outstanding electrical insulation qualities. It can be used to insulate electronic components when mixed with insulating adhesives. Additionally, polyester tape resists most organic solvents, acids, and bases.
The main uses of polyester tape range from low-end manufacturing to high-end industries.
Because of its many qualities, polyester tape is used in many different sectors. It is occasionally used with green adhesive tape that is heated to a high temperature. The following are specific applications:
Electronics manufacturing: Dual insulation and fixation.
In PCB production, polyester tape can be used to insulate the edges of circuit boards to prevent short circuits. Automotive Industry: An Ideal Choice for Wire Harness Fixation and Protection
The complex wiring harnesses within automobiles require adhesive tapes with high strength, high and low temperature resistance, and aging resistance. Polyester tape, with its high tensile strength and temperature resistance of -40°C to 150°C, is the preferred choice for wire harness fixation. Furthermore, during the body painting process, where temperatures exceed 120°C, polyester tape can also handle these applications at a lower cost, effectively reducing production costs.
Packaging and Logistics: High-Strength Strapping and Protection
For heavy cargo packaging or pallet strapping, polyester tape's high tensile strength allows it to securely secure goods and prevent them from loosening during transportation. Furthermore, polyester tape can also be used in consumer applications such as gift wrapping and label application, extending its application range far beyond the high-temperature green tape used primarily in industrial applications. New Energy: Auxiliary Materials for Batteries and Photovoltaic Modules
In lithium battery production, polyester tape is used for insulating and securing battery cells and tabs. If high-temperature processes (such as cell baking) are involved in the production process, high-temperature-resistant polyester tape is required. In photovoltaic module manufacturing, polyester tape is used to seal and secure the panels' frames. Its weather resistance ensures long-term outdoor use.
Printing and Marking: Precision Positioning and Masking
In screen printing, polyester tape can be used to mask areas where printing is not required. Its smoothness and stable adhesion ensure precise printing.
Key Selection Criteria
Temperature Resistance: Depending on the actual working temperature, use polyester tape that can withstand high temperatures.
Substrate Strength and Thickness: Select thin polyester tapes with a thickness of 0.02 to 0.05 mm for applications involving precision electronics. Select thicker polyester tapes with a thickness of 0.06mm to 0.1mm for mounting applications requiring great strength. Observe the tensile strength of the substrate, which is usually ≥200N/25mm. Type of Adhesive: Select silicone adhesive for high-temperature applications and acrylic adhesive for ordinary uses. Silicone polyester tape is used if resistance to adhesive residue is needed.
Insulation Performance: To guarantee adherence to circuit insulation standards, consider the breakdown voltage (usually ≥20kV/mm) in electronic insulation applications. Refer to the insulating specifications for high-temperature green adhesive tape for this performance.
Environmental Protection and Certification: RoHS and REACH laws, among others, must be followed by export goods. IATF16949 certification is required for automotive products, and UL certification is required for new energy products.
