Silicone Fusion Tape | 1in x 36ft Roll, Red with Blue Center StripeSilicone fusion tape is extruded of high performance silicone rubber, self adhering and self fusing. Cures into a solid rubber insulator at room temperature in 24 hours or less. Produces an inseparable barrier that resists moisture, ozone, and corona at temperatures up to 260C. High conductivity allows for rapid heat dissipation, resulting in lower temperature rise on all types of connections.
