3M Scotch 27 19x20 lasikuitukangasteippi valkoinen

The 3M Scotch 27 is a high-performance woven fiberglass cloth tape with thermosetting rubber adhesive, designed for demanding electrical insulation and high-temperature applications. This white tape offers excellent tensile strength, dielectric properties, and resistance to abrasion, solvents, and heat, making it ideal for coil wrapping, banding, and cable harnessing in motors, transformers, and other electrical equipment.

Advantages

With a temperature rating up to 150°C (302°F) and a dielectric strength of 3000 V, this tape provides reliable insulation in high-heat environments. The thermosetting adhesive ensures a secure bond that withstands thermal cycling and vibration. Its woven fiberglass backing offers high tensile strength (260 N/10mm) and low elongation (5%), making it suitable for applications requiring dimensional stability and mechanical reinforcement.

Suitable for

• High-temperature electrical insulation in motors, generators, and transformers
• Coil wrapping and banding of wire bundles
• Holding and securing components during assembly or repair
• Protection against abrasion and solvents in industrial environments
