The 3M Super 33+ 19x33 is a professional PVC electrical insulation tape, specifically designed for primary electrical insulation of wire and cable connections. It provides reliable protection for voltages up to 600 V and is characterised by high flexibility and formability, making it particularly suitable for applications in electrical installation. The tape features a moisture-resistant and UV-stable surface, making it suitable for use outdoors or in environments with high exposure to weather conditions. The material combination of elastic PVC carrier and strong adhesive ensures a tight, mechanically stable protection that retains its flexibility even at low temperatures down to –18 °C and does not become brittle. The maximum operating temperature is 105 °C, making the tape suitable for a wide range of applications in industry, construction, and electrical trades.

Applications
This insulation tape is primarily used for electrical insulation of cables and conductors, especially in installations with voltages up to 600 V. It is intended for use both indoors and outdoors, as well as above- and underground. Application areas include insulation of cable connections, covering of cable lugs, securing cable bundles, and protecting cable cut ends. Due to its chemical resistance to alkalis, solvents, and acids, it is also suitable for use in industrial environments with aggressive media.

Functions and Features in Detail
The tape consists of a PVC carrier material with a thickness of 0.178 mm, offering high elasticity and shape stability. The adhesive is a pressure-sensitive, rubber-based resin, providing strong adhesion to various surfaces. The tape is black in colour, making it visually distinct and supporting UV resistance. Dimensions are 19 mm width and 32.9 m length per roll, providing sufficient quantity for multiple applications. Packaging is in a transparent package, protecting the contents from damage while allowing product visibility.

Technology Explained Simply
The combination of elastic PVC carrier and strong adhesive ensures the tape conforms closely to the surface being insulated, avoiding air pockets or gaps. This is essential for reliable electrical protection. Moisture resistance prevents water ingress, securing insulation performance over time. UV resistance protects the material from degradation due to sunlight, which is especially important for outdoor applications. Temperature resistance from –18 °C to 105 °C enables use in a wide range of environments, from cold warehouses to warm industrial facilities.

Compatibility and Accessories
The tape is compatible with solid dielectric insulations, synthetic cable insulations, sheathings, and split connection joints. It is suitable for use with various cable types, particularly in installations requiring high mechanical and electrical load capacity. Certifications according to UL, CSA, and VDE confirm compliance with international safety standards. Sustainability certification UL ECOLOGO and compliance with RoHS (2011/65/EU) highlight the environmental compatibility of the product.

Installation and Mounting
Installation is performed by simply winding the tape around the area to be insulated. The elastic structure allows close adaptation to the surface, achieving a tight coverage. It is recommended to wind the tape with an overlap of approximately 50% to ensure optimal insulation. The tape can be used without additional tools or aids; it can be directly unrolled from the roll and applied.

Operational Advantages
The 3M Super 33+ offers high reliability and durability with minimal volume increase. The combination of electrical insulation, mechanical protection, and chemical resistance makes it a universally applicable product. Certifications according to UL, CSA, and VDE, as well as environmental compliance with RoHS and UL ECOLOGO, increase acceptance in professional applications. The tape remains flexible even under long-term stress and adheres securely, simplifying maintenance and inspection of installations.
