The Original Panasonic Fire-Retardant PVC Electrical Insulation Tape (Blue / 0.125mm–0.13mm Grade) is an industrial-grade, pressure-sensitive vinyl electrical tape engineered for primary electrical insulation, cable bundling, color-coding phase identification, and circuit repair. Formulated with premium flame-retardant polyvinyl chloride (PVC) backing and a high-tack rubber-based pressure-sensitive adhesive, it delivers high dielectric breakdown strength, excellent stretch conformability around irregular splices, and strong resistance to moisture, alkalis, dilute acids, and varying environmental conditions. Compliant with international flame-retardancy standards (such as JIS C 2336 / IEC 60454), the Panasonic blue insulation tape is widely utilized in residential and commercial electrical installations, switchboard phase marking, neutral line identification in specific electrical standards, low-voltage control circuits, and industrial maintenance.

Features

• Certified Flame Retardant: Self-extinguishes rapidly upon removal of open flames, preventing fire propagation along electrical conduit runs and distribution panels.
• High Dielectric Strength (>5000V): Provides safe, reliable primary electrical insulation for wiring splices rated up to 600V in residential, commercial, and industrial circuits.
• Superior Elastic Stretch (Up to 200%): Conforms tightly to irregular joints, terminal lugs, and bent conductors without tearing, creating a smooth, moisture-resistant barrier.
• Non-Corrosive Rubber Adhesive: High initial grab that leaves minimal gummy residue upon removal and does not corrode copper or aluminum conductors.
• Distinct Blue Color-Coding: High-visibility blue pigment ensures clear visual identification of Blue Phase (L3 / Phase C) in 3-phase AC distribution boards, or Neutral (N) lines in IEC harmonized systems.
• Weather & Moisture Resistant: Resists humidity, mild chemical exposure, and atmospheric aging, ensuring long-term bond strength without flag-peeling.

Common Applications

• 3-Phase Electrical Color Coding: Phase marking (Blue / L3 or Phase C) on main distribution boards, circuit breakers, busbars, and industrial motor feeds.
• Neutral & DC Polarity Identification: Marking neutral lines in standard IEC single-phase wiring or negative/signal reference lines in control panels.
• Cable Splicing & Primary Insulation: Primary insulation wrapping over twist-on wire connectors, inline solder splices, and crimp sleeves up to 600V.
• Low-Voltage Control & Automation: Identifying and bundling low-voltage control signals, PLC I/O lines, and sensor cabling in automation panels.
• HVAC & Marine Electrical: Insulating and weather-sealing control wiring in air conditioning units, marine electronics, and automotive harnesses.

Usage Tips

• Surface Preparation: Ensure the wire jacket and conductors are clean, dry, and free of oil, grease, or flux residues before applying the tape to achieve maximum adhesive bonding.
• Proper Wrapping Technique (Half-Lap & Tension):
  • Apply the tape with sufficient tension—stretching it to approximately 75% to 80% of its breaking elongation - to ensure tight conformance and eliminate internal air pockets.
  • Wrap in a half-lap pattern (each layer overlapping the previous layer by 50%), applying at least 2 to 4 layers over bare conductor splices.
• Preventing End "Flagging": On the final turn / wrap, release all stretching tension and apply the last 15–20 mm with zero stretch, pressing firmly. This prevents the tape end from creeping back or unpeeling ("flagging") over time.
• High-Voltage Layering: For applications exceeding 600V, apply self-amalgamating / rubber splicing tape as the primary insulation base, then overwrap with Panasonic PVC tape for mechanical protection and environmental sealing.
• Storage Conditions: Store unused rolls in a cool, dry place away from direct sunlight, high heat, and solvent vapors to preserve the elasticity and adhesive tack.
