Electrical insulation failure remains one of the leading causes of field returns in compact electronic devices. When space constraints force designers to reduce insulation layer thickness, the risk of dielectric breakdown increases significantly. Changshu Liangyi Tape Industry Co., Ltd. has developed a flame retardant insulation tape that directly addresses this engineering trade off, delivering dielectric breakdown voltage above 5.0 kV while maintaining a total thickness of only 0.055mm ±0.005mm.
The tape construction starts with a PET polyester film backing measuring 0.025mm in thickness. An acrylic adhesive system is applied to create the finished tape. This combination achieves a dielectric strength that exceeds many thicker insulation materials on the market. For engineers designing power supplies, battery management systems, or LED drivers, the ability to achieve >5.0 kV isolation with a thin profile enables smaller enclosure designs and tighter component packing.
Changshu Liangyi Tape Industry Co., Ltd. publishes a complete specification sheet that allows design engineers to validate material choices before prototyping. Key electrical properties include insulation resistance of at least 10⁶ Ω, which prevents leakage current across isolation boundaries. The acrylic adhesive contributes to this performance by maintaining consistent contact with the substrate under varying temperature and humidity conditions.
Thermal stability extends to 130℃ continuous operation. Many competing thin insulation tapes lose adhesive bond strength or soften at elevated temperatures, creating air gaps that reduce effective dielectric strength. The Changshu Liangyi flame retardant insulation tape maintains its mechanical and electrical properties across the full temperature range, ensuring that the 5.0 kV rating remains valid under actual operating conditions rather than just at room temperature.
For procurement managers and compliance engineers, the UL certification E246820 provides third party validation of both electrical and flame resistance claims. The tape carries a flame resistant classification, eliminating the need for separate fire retardant treatments in final assembly. This reduces both material cost and chemical handling requirements on the production floor.
The mechanical specifications of the tape support reliable automated application. Peel strength measures at least 250 N/m, ensuring that the tape stays in place under vibration and thermal cycling. Elongation reaches 40 percent, allowing the tape to conform to curved surfaces, wire bundles, and irregular component shapes without cracking or lifting at the edges. Width tolerance is held to ±0.2mm, which is essential for high speed automatic wrapping machines that index tape position optically.
Each roll of Changshu Liangyi flame retardant insulation tape contains a maximum of one splice over the standard 66 meter length. Splices in insulation tape create weak points where dielectric strength may be compromised. By controlling splice count, the company ensures that the >5.0 kV breakdown rating applies consistently along the entire roll length. Length tolerance is specified at ±0.5m, providing predictable roll usage for inventory planning.
The inner core diameter measures 76.64mm ±1mm, compatible with standard tape dispenser spindles and automatic applicator reel holders. Core options include plastic tube or paper tube, selected based on customer preference. The tape is available in multiple colors for visual process control, allowing assembly line operators to verify correct material usage at a glance.
Storage requirements are clearly defined at 23℃ and 65 percent relative humidity, with a validated shelf life of six months. For B2B buyers operating in different climate zones, this specification provides clear guidance for warehouse storage. Packaging consists of an inner plastic bag for moisture protection and an outer carton for mechanical protection during freight shipping.
Solvent retardance is rated as excellent for the acrylic adhesive system. This property becomes critical when the tape is applied to printed circuit boards that undergo subsequent cleaning or conformal coating processes. Solvent exposure does not cause edge lifting, adhesive bleed, or loss of dielectric strength.
Field applications for this flame retardant insulation tape include transformer layer insulation, capacitor wrapping, battery pack cell separation, and motor lead insulation. In each case, the combination of thin profile and high dielectric strength allows designers to meet safety standards without adding unnecessary material thickness.
For maintenance engineers and field service technicians, the tape provides a reliable repair solution for damaged wire insulation in tight spaces. The 40 percent elongation allows the tape to stretch slightly for tight wrapping, while the 250 N/m peel strength ensures the repair stays in place despite vibration or cable movement.
Changshu Liangyi Tape Industry Co., Ltd. maintains the specification sheet as a quality controlled document. Each production lot can be accompanied by a certificate of analysis upon request, supporting ISO 9001 quality management systems. The company's focus on dimensional precision, electrical performance, and flame resistance makes this product suitable for safety critical applications where insulation failure is not an option.
FAQ
1. What is the minimum insulation resistance guaranteed for this tape?
The specification sheet guarantees insulation resistance of at least 10⁶ Ω under standard test conditions. This value ensures effective isolation between conductors in low voltage and medium voltage electronic assemblies.
2. Can this tape be used as primary insulation on magnet wire?
Yes, the tape is suitable for overwrapping magnet wire coils in transformer and motor applications. The 5.0 kV dielectric breakdown provides margin above typical operating voltages for most industrial equipment.
3. Does the acrylic adhesive leave residue when removed?
Acrylic adhesives are designed for permanent application. Removal may leave some residue depending on the surface and duration of application. For temporary masking applications, a different adhesive system would be recommended.
4. How does the 130℃ temperature rating compare to standard PET tapes?
Standard PET insulation tapes are often rated at 105℃. The 130℃ rating of this Changshu Liangyi product allows use in higher temperature environments such as enclosed LED drivers and automotive electronics.
5. Is the tape compatible with automated cutting and placement machines?
Yes. The ±0.2mm width tolerance and ≤1 splice per roll make the tape suitable for automated cutting, feeding, and placement systems used in high volume electronics assembly.
