Why has Testex changed the formula for Press-O-Film?
“Old formulation” Press-O-Film softened at temperatures above 140 °F (60 °C). On the face of it, this would seem a safe operational upper limit. The highest recorded temperature on Earth is only 136 °F (58 °C) and the Threshold of Pain is less, approximately 125 °F (50 °C). Further, the maximum recommended temperature for application of many coatings is about the same as the Threshold of Pain. While it is difficult to imagine using replica tape at temperatures above 140 °F (60 °C) it is, however, possible to imagine storing the tape at those temperatures, especially if the product is kept in a closed container (specifically, a car) in direct sunlight on a very hot day. Here, temperatures can get well above outdoor-ambient. Press-O-Film HT’s new formulation adds 12 °F (6 °C) to the product’s softening point, a margin of safety that can be important to inspectors in extreme – and, especially, in remote – locations. In Testex’ internal testing even the old formula replica tape showed no h
