Is Basalt Fiber Insulation Tape strong in tensile strength?
Nov 29, 2025| Basalt Fiber Insulation Tape has high tensile strength, meeting the needs of most industrial applications.
Specifically, the tensile strength of conventional Basalt Fiber Insulation Tape is typically between 800-1200 MPa, with slight variations depending on the specifications. This strength level is significantly higher than that of fiberglass insulation tape, which generally has a tensile strength of 500-800 MPa, and also superior to some conventional resin-based insulation materials.
In practical use, this tensile strength allows the insulation tape to withstand a certain amount of tensile force. For example, during pipe winding construction, even with slight pulling and repositioning by workers, the insulation tape is unlikely to break or tear. When used for cable wrapping, it maintains structural integrity even under slight dragging during cable laying, preventing insulation layer damage due to tension.
However, it's important to note that if subjected to external forces far exceeding its withstand range, such as mechanically forcibly stretching it, Basalt Fiber Insulation Tape may still be damaged. Overall, its tensile strength is sufficient to handle the normal pulling forces encountered during daily installation and use, so there is no need to worry about insufficient tensile strength affecting its performance.
