Mylar can be aluminized by evaporating a thin film of metal onto it to reduce its permeability.
Color conferring dyes can easily be formulated into pet sheet.
As a guide to estimating changes due to thermal expansion figure 5 gives the dimensional changes in in over a wide temperature range.
This test method covers the assignment of the glass transition temperatures of materials using differential scanning calorimetry or differential thermal analysis.
Type mylar a is a tough general purpose film which is transparent in 12μm through 23μm and translucent in heavier thickness.
Bpf resins modified with heloxy modifiers 7 8 and 61 show a greater tendency to crystallize and should not be stored cold.
