Core Characteristics
Dual-Function Design
Combines semi-conductive properties (controls electrical flow to avoid static/ESD) with high-tack adhesion (bonds insulated materials securely). Eliminates the need for separate tapes (conductive + adhesive), reducing installation time and material costs.
01
Controlled Semi-Conductivity
Offers a surface resistance range of 10⁶–10¹² ohms/sq (the "semi-conducting" sweet spot)-low enough to dissipate static charge but high enough to avoid short circuits in insulated systems. This prevents damage to sensitive components (e.g., electronics) from ESD.
02
Insulation Compatibility
Adheres strongly to common insulated materials, including cross-linked polyethylene (XLPE), ethylene propylene diene monomer (EPDM) rubber, PVC insulation, and fiberglass. The adhesive won't degrade or corrode insulation surfaces over time.
03
Environmental Resistance
Withstands moisture, temperature fluctuations, and mild chemicals (e.g., industrial cleaning agents). It maintains semi-conductivity and adhesion in conditions ranging from -40°C (-40°F) to 120°C (248°F), making it suitable for indoor and outdoor use.
04
Flexibility & Conformability
Thin, flexible construction allows it to wrap around curved insulated surfaces (e.g., wires, pipes) or conform to irregular shapes without cracking. This ensures full contact between the tape and insulation, maximizing both bond strength and semi-conductive performance.
05
Key Technical Parameters
| Parameter | Typical Range | Description |
|---|---|---|
| Thickness | 0.15mm – 0.5mm | Thin enough to avoid adding bulk to insulated components; thicker options (0.3–0.5mm) for heavy-duty bonding. |
| Width | 10mm – 500mm (customizable) | Standard widths (10–50mm) for wiring; custom widths for large insulated surfaces (e.g., industrial pipes). |
| Length | 25m – 100m (per roll) | Rolls for easy storage and precise cutting to project lengths. |
| Surface Resistance | 10⁶ – 10¹² ohms/sq | Defines semi-conductivity; values outside this range are either insulating (>10¹²) or fully conductive (<10⁶). |
| Adhesion Strength | ≥ 5 N/25mm (to XLPE insulation) | Measures bond strength to insulated materials; higher values indicate more secure adhesion. |
| Temperature Range | -40°C to 120°C (-40°F to 248°F) | Maintains performance in extreme cold (e.g., outdoor wiring) and moderate heat (e.g., engine bays). |
| Moisture Absorption | ≤ 0.5% (24-hour immersion) | Low absorption prevents loss of semi-conductivity or adhesion in humid environments. |
| Flammability Rating | UL 94 V-0 (common) | Self-extinguishing to meet safety standards for electrical and industrial applications. |
Competitive Advantages
1.Eliminates "Double-Taping" Hassles: Unlike traditional setups (using conductive tape + separate adhesive tape), this product integrates both functions-saving time and reducing the risk of bond failure from mismatched materials.
2.Protects Sensitive Components: Controlled semi-conductivity dissipates static charge without causing short circuits, making it safer for use with electronics (e.g., circuit board insulation) or explosive environments (e.g., chemical plants with flammable dust).
3.Longer Bond Lifespan Than Standard Tapes: The adhesive is formulated to resist aging and degradation, maintaining a strong bond with insulated materials for 5–8 years-twice as long as generic adhesive tapes.
4.Versatile Across Insulation Types: Works with all major insulated materials (XLPE, EPDM, PVC, fiberglass) without requiring surface treatment (e.g., sanding or priming), simplifying installation.

FAQ
Q1: Can This Tape Be Used On High-Voltage Insulated Cables (E.G., 10kV+)?
A1: Yes-our tape is rated for use with high-voltage insulation (up to 35kV) when installed correctly. It dissipates static charge without conducting high voltage, preventing arcing between cable insulation layers.
Q2: Will The Adhesive Damage Fragile Insulation (E.G., Thin PVC On Electronics)?
A2: No- the adhesive is low-tack enough to avoid tearing thin insulation but strong enough to maintain a secure bond. For ultra-fragile insulation (e.g., 0.05mm PVC), we offer a low-adhesion variant upon request.
Q3: How Do I Test If The Tape Is Maintaining Semi-Conductivity?
A3: Use a surface resistance meter to measure ohms/sq-values should remain within 10⁶–10¹² ohms. Test annually for outdoor applications (exposed to weather) or every 2–3 years for indoor use.
Q4: The Tape Is Peeling From EPDM Insulation-What's Wrong?
A4: Peeling usually occurs if the EPDM surface is dirty or oily. Clean the insulation with isopropyl alcohol (to remove grease) before applying the tape, and press firmly for 30 seconds to ensure full adhesion.
Q5: Can It Be Used In Wet Environments (E.G., Outdoor Wiring)?
A5: Yes- the tape's moisture absorption rate is ≤0.5%, so it maintains semi-conductivity and adhesion in rain, humidity, or even temporary water immersion (e.g., flooded basements).
Q6: Is This Tape Recyclable?
A6: Yes- most variants are recyclable (check the product label for specific recycling codes). We also offer a take-back program for scrap tape, repurposing it into low-grade semi-conducting materials to reduce waste.
