TESA 4688 PE-Coated Cloth Tape: Nuclear-Certified 260μm Repair Tape for Harsh Environments

I. Core Product Positioning

The ultimate industrial repair tape certified for nuclear applications, delivering:
✔ TLV 9027/01-06 compliance (<1000ppm halogens/sulfur)
✔ 52N/cm adhesion on rough surfaces
✔ Waterproof sealing with 55% sustainable content

II. Technical Parameters

Parameter Specification Industry Value
Construction PET/Rayon woven fabric 55 mesh count for optimal flexibility
Coating PE + Natural Rubber Chemical/abrasion resistance
Thickness 260μm (10.24mils) Withstands 500+ wire brush cycles
Dielectric Strength 2900V Temporary electrical insulation
Temp Resistance 110℃ for 30min Short-term high-heat exposure

III. Four Critical Advantages

1. Nuclear-Grade Safety
  • Meets Siemens TLV 9027 for power plant maintenance
  • Case: Coolant pipe temporary seals during reactor servicing
2. Extreme Surface Adaptability
  • Maintains 8N/cm adhesion on rusted metal
  • 90° edge retention without lifting
3. Military-Grade Protection
  • IP67 waterproof (1m/72hr immersion)
  • Salt spray resistant for 48hr+
4. Operator-Friendly
  • Hand-tearable without tools
  • Low 1.5N unwinding force

IV. Application Protocols

1. Nuclear Facility Maintenance
  • Use Case: Pipe marking/equipment protection
  • Procedure:
    1. Clean with acetone
    2. Apply at 50% stretch
    3. Double-layer for >110℃ environments
2. Industrial Cable Management
  • Precautions:
    1. UV shield required for permanent outdoor use
    2. Incompatible with hydrocarbon solvents

V. Technical Q&A

❓ Q: Transformer sealing suitable?
→ Temporary use only (<72hr); pair with sealant for permanence

❓ Q: vs 3M 2929?
→ 20℃ higher temp tolerance with 40% greater thickness
