3M Scotch 70 Self-Fusing Silicone Rubber Electrical Tape, Sky Blue Grey, 25.4mm

The 3M Scotch 70 is a premium, self-fusing silicone rubber tape engineered for high-performance electrical insulation in demanding environments. Composed of a specialised, inorganic silicone rubber compound, it fuses to itself upon application to form a seamless, non-tacky, and permanent rubbery seal without requiring any adhesive. This unique self-fusing property ensures excellent protection against moisture, dust, and contaminants.

Rated as a Class H material, this tape is designed for continuous operation at temperatures up to 180°C, making it ideal for high-temperature applications. It exhibits outstanding arc and track resistance, which is crucial for protecting high-voltage cables and connections from electrical tracking and corona discharge. Its high dielectric strength provides reliable insulation for electrical components and splices.

Key Features & Benefits

• Self-Fusing Action: The tape bonds only to itself, creating a homogenous, void-free rubber sleeve that will not unravel or become sticky over time.
• High Temperature Resistance: Suitable for continuous use at 180°C, ensuring performance in hot environments such as motors, transformers, and generators.
• Excellent Conformability: Easily wraps around irregular shapes, corners, and bends, providing a snug, professional finish on cables and connectors.
• Instantaneous Fusion: Starts fusing on contact, eliminating the need to hold the tape in place during application.
• Low-Temperature Flexibility: Remains workable and pliable in extremely cold conditions, allowing for installation in a wide range of climates.
• Superior Ozone Resistance: Withstands degradation from ozone exposure, prolonging service life in electrical applications.
• Easy to Use: Features an easy-tear, easy-strip liner for quick and clean dispensing without the need for scissors.
• Standard Colour: Matches the Sky-B
