Testex Inc. is introducing a new version of its Press-O-Film replica tape to withstand higher temperatures without softening.
The new formulation of its Coarse and X-Coarse grades of Press-O-Film replica tape is designed for better performance at the elevated temperatures (above 140°F or 60° C) encountered in the most challenging environments, the company says. While stable at 140 °F, earlier formulation Press-O-Film gradually softened at higher temperatures. The new Press-O-Film HT adds a 12 °F (6 °C) safety margin.
Other physical properties remain nearly identical, except for some loss of agreement where different grades overlap, according to Testex. The effect is most noticeable between Coarse and X-Coarse grades. The new instructions will recommend that where these two grades give different profiles, and both are in the range of 1.5 to 2.5 mils (38 to 64 µm), those differing values be averaged.
Press-O-Film on the old-design tapes may be safely used with the new instructions.
In most applications, users will notice little change in the product, the company says. Press-O-Film HT will be sold on a different label but at the same price. The new version will replace the existing product.
