Technical Specifications & Material Science

Material structure and ESD function

Anti-static polyimide tape uses polyimide film as the backing because polyimide maintains mechanical stability, dielectric performance, and dimensional accuracy under temperatures that exceed the range of many general-purpose films. The anti-static treatment adds controlled surface behavior, allowing the tape to dissipate charge more safely in static-sensitive environments. :contentReference[oaicite:2]{index=2}

The product page specifies polyimide film (ESD treated), a surface resistance of 10⁶–10⁹ Ω, continuous temperature resistance up to 260°C, short-term peak up to 300°C+, dielectric strength of at least 6.0 kV/mm, and a thickness range of 0.03 mm to 0.10 mm. The uploaded product catalog also shows representative models such as JTT-ESPI050-SI, JTT-ESPI050-AC, JTT-ESPI075-SI, JTT-ESPI050-LS, JTT-ESPI060-GR, and JTT-ESPI100-DS, confirming that the anti-static polyimide range includes silicone, acrylic, low-static-peeling, conductive-grid, and double-sided options. :contentReference[oaicite:3]{index=3} :contentReference[oaicite:4]{index=4}

From an application-engineering perspective, the main value of this tape is not heat resistance alone. It is the combination of high-temperature stability, electrical insulation, and controlled electrostatic behavior that makes it useful in electronics manufacturing and rework. Where standard polyimide tape can tolerate heat but does not manage static, anti-static polyimide tape provides an additional process-safety benefit. :contentReference[oaicite:5]{index=5}

For reference standards, industrial buyers often compare insulating tape test data against frameworks such as ASTM D1000 and general electrical tape requirements such as IEC 60454-1. These standards are useful for evaluation context, but should not be treated as product certification unless explicitly stated by the manufacturer. :contentReference[oaicite:7]{index=7}

Industrial Applications

1. PCB masking in static-sensitive assembly

During PCB assembly and rework, a masking tape may be exposed to heat while remaining close to ESD-sensitive components. Anti-static polyimide tape is used because it reduces charge accumulation while maintaining the thermal performance expected from polyimide film. This is why it is more appropriate than ordinary masking tape in sensitive electronics work. :contentReference[oaicite:8]{index=8}

2. Electronics manufacturing and repair

In electronics repair, peeling and repositioning tape can itself become an ESD risk. Anti-static polyimide tape addresses that issue by combining heat tolerance with controlled surface resistance. It is therefore relevant in solder-adjacent work, fixture masking, and repair environments where static control cannot be separated from thermal requirements. :contentReference[oaicite:9]{index=9}

3. Coil, motor, and transformer wrapping

These applications require stable dielectric insulation and heat resistance. Where the assembly environment also includes static-sensitive electronics or test interfaces, anti-static polyimide tape can provide an additional margin of process safety. The polyimide backing contributes thermal and mechanical stability, while the ESD behavior helps control charge on the tape surface. :contentReference[oaicite:10]{index=10}

4. Static-sensitive industrial surface protection

The tape is also used for temporary protection of fixtures, process areas, or electronic surfaces that need insulation and controlled handling under elevated temperature. In these cases, the requirement is not just adhesion or insulation, but a material that is less likely to become a static source during repeated contact or removal. :contentReference[oaicite:11]{index=11}

Material Comparison

Anti-static Polyimide Tape vs. Standard Polyimide Tape

Silicone adhesive vs. acrylic adhesive

Within the anti-static polyimide family, silicone adhesive is generally the better choice for higher-temperature processes and more stable performance under heat. Acrylic adhesive may be used where lower process temperatures and stronger room-temperature adhesion are preferred. The right decision depends on actual line conditions, not only on the tape name. :contentReference[oaicite:13]{index=13} :contentReference[oaicite:14]{index=14}

Customization & Supply Capabilities

As a manufacturer, JIAOTAOTAO can support industrial buyers with process-ready supply rather than only stock rolls. That matters because anti-static polyimide tape is frequently used in specific widths, localized masking zones, or die-cut insulation parts in electronics manufacturing. :contentReference[oaicite:15]{index=15} :contentReference[oaicite:16]{index=16}

• Custom widths: suitable for local masking and narrow insulation paths
• Slitting: converting jumbo rolls into production-ready sub-rolls
• Rewinding: custom roll lengths for repair or assembly stations
• Die-cutting: pads, tabs, windows, and insulation shapes
• MOQ flexibility: suitable for pilot runs and evaluation
• Free samples for testing: useful for ESD validation and process qualification
• OEM supply: for converters, distributors, and direct industrial buyers

FAQ

1. What surface resistance does anti-static polyimide tape usually provide?

The product page lists a typical 10⁶–10⁹ Ω surface resistance range. That is commonly associated with static-dissipative materials. Buyers should still confirm the target ESD level and validate performance under their own environmental and handling conditions. :contentReference[oaicite:17]{index=17}

2. Can anti-static polyimide tape handle soldering or other high-temperature processes?

Yes. The published data states continuous use up to 260°C and short-term peaks up to 300°C+. Final suitability depends on dwell time, substrate, pressure, and whether the tape is used for masking, insulation, or temporary surface protection. :contentReference[oaicite:18]{index=18}

3. Is it better than standard polyimide tape for electronics assembly?

It is better when the process includes ESD-sensitive components and there is a risk of charge generation during handling or peel-off. If the process only needs heat resistance and insulation, standard polyimide tape may be adequate. :contentReference[oaicite:19]{index=19}

4. Does the tape leave residue after removal?

Residue behavior depends on adhesive type, substrate, exposure temperature, dwell time, and peel angle. High-temperature silicone versions are generally better suited to elevated thermal conditions, but residue-sensitive applications should always be tested on the actual surface. :contentReference[oaicite:20]{index=20} :contentReference[oaicite:21]{index=21}

5. Which adhesive should buyers choose: silicone or acrylic?

Silicone is usually preferred for higher-temperature masking and insulation because it remains more stable under heat. Acrylic may be more suitable for lower-temperature applications where stronger room-temperature adhesion is needed. The right choice depends on the process window. :contentReference[oaicite:22]{index=22} :contentReference[oaicite:23]{index=23}

6. Can it be supplied in custom widths or die-cut shapes?

Yes. The product family can be converted into slit rolls, rewound rolls, pads, tabs, and other die-cut parts. This is especially useful in PCB masking, fixture protection, and localized insulation where exact geometry improves process control. :contentReference[oaicite:24]{index=24} :contentReference[oaicite:25]{index=25}

7. How should buyers evaluate it before a volume order?

Testing should include surface resistance, thermal exposure performance, removal behavior, insulation needs, and compatibility with the actual substrate. The most reliable method is line-condition testing in the real assembly or repair process. :contentReference[oaicite:26]{index=26}
