Mylar can be aluminized by evaporating a thin film of metal onto it to reduce its permeability.
Mylar glass transition data sheet.
Glass transition temperature t g 67 81 c.
How to measure glass transition temperature the most usual test method to determine glass transition temperature of plastics is astm e1356.
Multiplying the indicated change by the sample length gives the thermal dimensional change in the sheet of mylar.
This data sheet also covers the following dupont teijin films which are not branded as mylar products.
As a guide to estimating changes due to thermal expansion figure 5 gives the dimensional changes in in over a wide temperature range.
Bpf resins modified with heloxy modifiers 7 8 and 61 show a greater tendency to crystallize and should not be stored cold.

Mylar polyester film is a flexible strong and durable film with an unusual balance of properties making it suitable for many industrial applications.
When filled with glass particles or fibres.
This test method covers the assignment of the glass transition temperatures of materials using differential scanning calorimetry or differential thermal analysis.
Crystallization of bpf epoxy resins is possible in the temperature range between the glass transition point 10 to 20 c 14 to 4 f and the general melting range typically 30 to 60 c 86 to 140 f.
