Heat Cable Tape for Pipe & Roof Applications

Product Overview

Heat cable installation tape is used to securely fasten self-regulating cable to pipes and roofing surfaces during freeze protection installs.

  •  3M™ Scotch 27 Glass Cloth Electrical Tape is a white, woven glass cloth electrical tape designed for applications requiring high mechanical strength and elevated temperature resistance.
  • The Class B thermal rating makes it suitable for industrial heating systems and electrical insulation where temperatures are moderate but still demanding.
  • Woven glass cloth backing provides excellent tensile strength, tear resistance, and abrasion resistance.
  • Coated with a thermosetting rubber pressure-sensitive adhesive that does not require heat or moisture to activate.
  • Adhesive is specially designed and prepared to provide corrosion protection
  • Recommended for steel pipes, which naturally conduct heat effectively
  • Used for Pipe trace installation

Compatible With

  • Self-regulating heat cable

  • Pipe heat trace systems

  • Roof and gutter deicing cable

Applications

  • Pipe freeze protection

  • Roof ice dam prevention

  • Custom heat cable installations

🧱 Construction & Composition

  • Woven glass cloth backing provides excellent tensile strength, tear resistance, and abrasion resistance.
  • Coated with a thermosetting rubber pressure-sensitive adhesive that does not require heat or moisture to activate.

🌡️ Temperature & Electrical Ratings

  • Class B insulation — continuous use up to 130 °C (266 °F), short-term peaks up to ~160–175 °C.
  • Suitable for 600 V dry electrical applications.

🛠️ Mechanical & Electrical Properties

  • High tensile and tear strength — good mechanical protection in demanding environments.
  • Conformable and edge-tear resistant, making it easy to wrap around irregular shapes.
  • Corrosion protection adhesive helps protect underlying metal surfaces.
  • Printable surface for marking or labeling during installation.

🧪 Certifications & Compliance

  • UL Recognized under UL Standard 510.
