Color conferring dyes can easily be formulated into pet sheet. Bpf resins modified with heloxy modifiers 7 8 and 61 show a greater tendency to crystallize and should not be stored cold. Vicat softening point astm d1525. How to measure glass transition temperature the most usual test method to determine glass transition temperature of plastics is astm e1356.

As a guide to estimating changes due to thermal expansion figure 5 gives the dimensional changes in in over a wide temperature range. Multiplying the indicated change by the sample length gives the thermal dimensional change in the sheet of mylar. Glass transition temp tg dsc. This page displays only the text of a material data sheet.

Dupont teijin films types db g2 n5 s1 s2 x2 x2i. This data sheet also covers the following dupont teijin films which are not branded as mylar products. This test method covers the assignment of the glass transition temperatures of materials using differential scanning calorimetry or differential thermal analysis. Mylar can be aluminized by evaporating a thin film of metal onto it to reduce its permeability.
