Aluminum duct tape is pressure sensitive adhesive tape. When applied the tape, we usually wrapping or sticking the tape on the duct substrate.
Application temperature is exactly the temperature at the point that the tape is applied. Application temperature can impact how quickly an aluminum duct tape bonds with the surface to which it is applied and potentially how strong that bond is. The acrylic adhesive coated aluminum foil duct tape, Application Temperature from -10℃ to +40℃.
Service temperature is the temperature to which foil duct tape will need to withstand throughout the life cycle of the system after application. The risk for tape failure increases when tapes that are not built to regularly withstand extreme temperatures are used in HVAC duct systems. If your system will be exposed to temperatures under -30℃ or above 150℃, you should consider a tape that is labeled as having a service temperature with a greater range in order to ensure strong performance.
