product detail

Exceptional Strength for Extreme Thermal Environments 3M™ Tape 361 is engineered for applications requiring high thermal resistance and superior mechanical toughness. The woven glass cloth backing is extremely durable, offering high tensile strength and resistance to punctures and tears. Combined with a high-performance silicone adhesive, this tape excels in masking, bundling, and sealing applications where temperatures can reach 230°C (450°F), making it an essential tool for aerospace, automotive, and industrial maintenance.

Key Technical Advantages

  • High Thermal Stability: Performs reliably at continuous high temperatures, outlasting standard cloth tapes.

  • Superior Tensile Strength: The fiberglass backing ensures the tape will not stretch or break under heavy mechanical loads.

  • Flame Retardancy: Meets various aerospace and industrial flame-resistant specifications for enhanced safety.

  • Chemical & Abrasion Resistance: Provides a robust protective barrier against harsh chemicals and physical wear.
