FEP heat shrink tube,maximum continuous working temperature is 200°C, the shrinking temperature is only 110°C.Used initially for UV lamps in electronic fly killers, and subsequently for white lights, FEP has proved to be the ultimate coating material for shatterproofing lamps for this application. It allows glass and mercury to be safely contained when breakage occurs, yet does not become degraded by the heat or UV emitted by the lamps.
