Panduit ST88-100-108BK 1" × 108' PVC Electrical Tape

Panduit ST88-100-108BK StrongHold Heavy-Duty PVC Electrical Tape

The Panduit ST88-100-108BK delivers UL 510-listed primary insulation performance for splicing applications up to 600V and 80°C (176°F), combining weather-resistant PVC construction with pressure-sensitive adhesive that maintains bond integrity across wide temperature swings. Sized at 1" width × 108 feet length × 0.0085" thickness, this black electrical tape meets ASTM D-3005 Type 1 and EN 60454-3-1 Type 11 standards for mechanical and electrical performance, making it the go-to choice for electrical construction, industrial builds, and mission-critical maintenance work where code compliance and long-term reliability matter. Each roll ships individually wrapped in cellophane to prevent contamination before use.

Key Features

• UL 510 and CSA C22.2 No. 197 listed for primary insulation up to 600V or 80°C (176°F)
• Weather-resistant PVC construction with flame-retardant formulation per UL 510
• Pressure-sensitive adhesive applies easily and maintains bond across temperature extremes
• 1" × 108' × 0.0085" dimensions provide substantial coverage for splice and jacketing applications
• Meets ASTM D-3005 Type 1 and EN 60454-3-1 Type 11 mechanical/electrical standards
• RoHS 2011/65/EU and 2000/53/EC compliant for European installations
• Individually cellophane-wrapped to prevent adhesive degradation in storage

The ST88-100-108BK's PVC backing delivers the conformability you need when wrapping irregular splice geometries or building up protective jackets over low-voltage terminations. The pressure-sensitive adhesive system bonds immediately on contact without requiring heat activation, and maintains that bond whether you're working in a climate-controlled data center or an outdoor enclosure seeing seasonal temperature cycles. The 0.0085" thickness strikes the balance between mechanical protection and bulk—thick enough to provide abrasion resistance and dielectric strength for primary insulation duty up to 600V, but thin enough that you're not fighting excessive build-up when wrapping tight bundles or working in crowded j-boxes. The flame-retardant formulation meets UL 510 requirements, ensuring the tape won't contribute to fire propagation if a fault condition develops.

Electrical contractors reach for this tape when splicing branch circuits in commercial TI work, industrial electricians spec it for motor leads and control wiring in manufacturing environments, and low-voltage installers use it as outer jacketing over heat-shrink primary insulation on access control and intrusion detection home-runs. The 108-foot roll length gives you enough material to handle multiple splices or a long cable repair without mid-job roll changes, and the 1" width covers most 12-14 AWG splices in two wraps or provides clean jacketing over bundled Cat6 pairs. The individual cellophane wrap prevents shelf contamination—critical when tape sits in a truck or job trailer for weeks between uses—and the carton quantity of 80 rolls lets you stock maintenance shops or distribute across field crews without constant reordering.

Compliance spans UL 510, CSA C22.2 No. 197, ASTM D-3005 Type 1, and EN 60454-3-1 Type 11, covering North American electrical code requirements and European low-voltage directive installations. RoHS 2011/65/EU certification ensures you can use this tape on EU-market equipment builds without material disclosure issues. For integrators running access control risers, IP camera POE drops, or intrusion detection loops where long-term reliability and inspector acceptance matter more than price-per-roll, the ST88-100-108BK combines the material performance, standards compliance, and Panduit manufacturing consistency that keeps callbacks and re-inspections off your schedule.
